Repairing PVC Piping

Repairing PVC Piping

PVC pipes are one of the most common things that every house has. There is a chance that you may need to repair the pipes. There are some tips on how you can handle PVC piping repairs.

Cracks on the Pipes

One of the most usual types of fixes you need to do will be repairing breaks or cracks in PVC pipes in the house. Depending upon the seriousness of the crack, you can use sealant to fix the cracked area on the PVC pipe. Still, it is significant to remember that the sealant will take time to set.

Silicone Solvents

You can use silicone solvents to repair PVC pipes, but it can only be used for almost everything excluding hairline cracks and main lines in your home. Fine quality silicone sealant will be available at home repair.

Replacing the Pipe

Before replacing the section, ensure you have noted the length of PVC pipe of the original pipe as well as its thickness. You will have to apply sealant on each end of the pipe and then will have to add coupling to both points. Next, set the pipe at the right place. Remember to apply sealant to your main piping and sliding the couplings on both the points of the original line, thus making a sealed portion. You will also have to use channel locks for the coupling until the sealant has set.

Using PVC Pipe

Using PVC Pipe

PVC Pipe is a versatile form of pipe which has revolutionized modern plumbing. PVC can be used for drainage, waste water or vent piping but is not suitable for water supply, in which case, copper pipe is most commonly used.

PVC stands for Polyvinyl Chloride which is a compound designed for strength and durability. It is resistant to corrosive materials found in cleaners and other household chemicals and also to the extremes of hard and soft water. It resists leakage and does not conduct electricity. For these reasons it is the common choice for modern plumbing and for replacing old plumbing.

There are many different sizes, lengths and diameters of PVC pope available. Pipes are designed to fit within each other and fixed with solvent cement. PVC pipes are measured by their inside diameter.

A coupling is the term used to describe a join between two pieces of PVC pipe, in particular when they are joined with no angle. Joins can be of varying degrees however, typically they are 22, 45, 60 and 90 degrees. An angled join is generally called an elbow.

Transition pieces are available to allow connection with other types of piping. A threaded adapter is available which will allow joining between threaded galvanized pipe. For connecting to non threaded metal pipe a gasket can be used which threads over both ends of pipe and is then secured in place using stainless steel clamps.

When fitting PVC pipes be sure to wear protective eye wear and a mask. Cut using a PVC hand saw and then use a deburring tool or the tip of the saw to remove any rough edges, especially from the inside of the pipe. Dry fit the pipes together to ensure that they are a good fit before applying solvent cement. Mark out exactly where the pipes will be joined together as once you apply the cement you will need to act quickly.

Joining PVC pipes is a two step process. Firstly a primer is applied, which cleans the area and begins a chemical reaction with the pipe. Spread primer on the outside of the pipe and on the inside of the fitting. Next spread cement over the same areas of the piping. Once the cement has been applied insert the pipe and hold for a few seconds for the cement to set. Always work in a well ventilated area and wear a face mask, as these chemicals can have quite a powerful odor. Run some water through the join to ensure that a good seal has been made.

PVC pipe is extremely versatile and hardy and the creative home improver can find many projects involving its use, including bird feeders, storage, hanging planters and more.

Once done with PVC, move inside and undertake some area rug decorating.

Cold Pipe Insulation

Cold Pipe Insulation

Using Insulation Jackets on Cold Pipe Systems

Insulation is not just used for containing heat. It is also used to control cold pipe systems and keep them functioning properly and in good repair.

There are several issues to be dealt with when using insulation jackets on cold pipe systems. The first and possibly most important concern is controlling condensation. When the cold pipe system contacts the air, condensation will form once the pipe system is below the dew point of the ambient air. This condensation can aversely effect the quality of the pipes and cause mould, ice, and degradation of the pipe material.

Insulation jackets need to be specially designed with sufficient thickness and vapor retardation qualities to keep condensation from gathering. Condensation causes corrosion of metal and decreased efficacy of insulating materials in the insulation jackets.

Insulating Cold Pipes vs. Insulating Hot Pipes

It is a common misconception that cold insulation materials can be the same as insulation for hot systems. In reality, there are several differences between cold system insulation needs and hot system insulation needs.

• Closed cell structure: Closed cell structure is necessary to avoid wicking behavior. Most open celled material used for hot pipe systems allows water to enter because the heat will cause the moisture to evaporate before it can corrode the metal. This same moisture ingress is very detrimental to cold systems because the moisture does not evaporate.
• Effective Water Vapor Barriers: Preventing condensation from gathering directly on the metal surface being insulated a key part of avoiding metal degradation. A solid, flexible water vapor barrier is necessary to prevent water from condensing on the metal pipe surface. This type of water vapor barrier is not necessary for hot systems.
• No Thermal Bridging Potential: Often, there are strangely shaped or bent connections that are left un-insulated because their size and shape make them hard to find insulation for. Examples include expansion joints, triple duty valves, and flange sets. These types of joints are potential thermal bridge points if left un-insulated. In cold systems, they will collect moisture. Bendable or flexible insulation is needed to protect against this.

Cold Pipe Insulation Materials

There are several types of materials that can be used to insulate cold systems. When combined with the appropriate vapor barriers, materials like fiberglass, mineral wool and cellular glass are rated for low temperatures. Because of their flexible and closed-cell nature, foam polyurethanes are also popular for insulating cold pipe systems. There are many types of flexible and rigid insulation techniques for cold pipe systems that involve a number of variations in materials used.

Ideal Cold Pipe Insulation Characteristics

1. Strong vapor barrier capability
2. Closed sell, non wicking components
3. Air tight application
   Often, materials that include all of these characteristics have one major drawback. Getting to the actual pipe surface for maintenance purposes often involves damaging or permanently removing the insulation that was applied. This can get rather expensive, especially if the area that needs to be reached is a valve that needs to be freely accessible. There are several removable insulation options for cold pipe systems that make reaching these areas easier and less costly.

William Jones has been in the heating and cooling industry for the past 37 years. Starting out in 1972 in the plumbing and heating industry, he obtained his Journeyman Plumbers license, then his Master Plumbers license and in Connecticut the P-1 unlimited Plumbing and Piping license. William studied Mechanical Engineering at the University of New Haven.

Being extremely interested in boilers and steam he then spent several years as a sales engineer concentrating on insulating steam systems and thermal efficiency. This experience in thermal efficiency led William to the point of being the foremost designer of reusable, removable insulation jackets in the United States. William is responsible for the design and specification of the Thermaxx LLC removable insulation covers.

How to Design Piping Systems

Piping design is a very interesting subject and a profession too which needs a lot of serious concentration and visualization. Design piping systems mainly consists of Plot plans, Piping Plans, Piping Isometrics, Bulk Material take-off, Project material take-off, Tie-in Schedule, and finally Support Schedule.

How to Design Piping Systems – Concentration and Visualization.

Concentration and visualization go hand to hand. How important is concentration and visualization on subject of how to design piping system? Is your first question right, I would also have the same query popping up in my mind if I get in to your shoes and observe the scenario from your window.

Honestly and very, very honestly a passionate piping designer should be so fanatical that colleagues looking at him should feel that he/she has driven crazy. Well here I would like to share my practical experience with you, this was in my office once I was routing a 36” line I was in to my deep visualization, observing the route of my 36” line I was in stagnant my eyes were looking straight and unfortunately the other side on me was beautiful newly recruited co-partner Ms Alana (name changed).

Alana was under an impression that I was lusty about her but seriously I was observing the dramatic routing of my 36” line and its branches, after a short while she saw me walking a few steps to right holding my selves looking up in the air at short intervals with both my hands in my pocket, well by now she was quite sure that I was mentally psychic. But gradually and almost immediately she was acknowledged about my intensity of concentration and visualization.

But ever since the advanced technology has introduced innumerable solutions and software’s which neither consume less time, paper and paper work but also make the piping design an easy task, for example PDMS.
How to Design Piping Systems – Plot Plans (PP)

PP plays a vital role from the very initial stage after winning an engineering contract. The PP’s are usually generated in a very speedy pace and also contains very restricted information. This key deliverable is thus initially generated with only tentatively positioned equipments, pipe racks with dimensions, location and sizes, the only purpose of which is to get a rough idea of the plant.

Further the constructability is then assessed and this deliverable is released for the client’s approval. Subsequently the copies are circulated to departments of Engineering, Planning, Construction, Operations, Cost and Estimation and finally Purchase as symbolic orientation and acts as a universal document utilized by the inter-disciplines including the client.
How to Design Piping Systems – Plot Plans Development

PP’s in the primary phase are developed very proficiently depending on the project design specifications with estimated sizes of equipments and Process Flow Diagram’s (PFD) to verify structural model and virtual equipment arrangement.

All the huge diameter piping headers and expensive piping such as alloy piping and the major pipe racks are illustrated as compelled by PFD’s. Usually high costing pipes are mentioned in different colors, whereas the process piping connected to the equipments are highlighted in separate colors to identify the costing with ease.

As PP’s are the vivacious document sprouting through the entire life of the plant, it is described in different names in different stages of progress in a process plant. Hence the list of PP’s with respect to level of progress follows:-

· Proposed PP: - Specially developed for bidding the project.

· For Approval PP: - Released for client’s approval with the information of space availability, roads, surrounding occupied areas, highlighting the fouling information.

· Overall PP: - Describing the utility, storage area, unloading and loading areas of a particular process plant etc.

How to Design Piping Systems – Plot Plans Major role

· PP’s are necessary for achieving Safety permits and verifying ecological or environmental and employee’s safety. These are the most important documents used in evaluating fire protection.

· PP’s are the major references to measure completion of project during the courses of construction, PP’s thus help in terms of payments after partial completion of project.

· Prevailing winds shall also be taken in to consideration subjected to towers high structures and various equipments at higher elevations.

· Though the directions of winds are always invariable throughout the year still it has to be taken in to consideration for the safety of adjacent residential or commercial areas.

· High elevated structure or towers are mostly considered if the plant is located near the airport.

· Climatic conditions play a vital role in designing a PP for extremely hot deserts wherein the provision of sun shades for the maintenance and operators are mandatory.

· On the other hand the structural shades with a provision of enclosed heating shelters shall be considered at extreme low temperature areas. For example Snow or ice.
