Fiberglass Pipe Insulation

Fiberglass pipe insulation has been widely used for insulating water pipes in homes and drainage systems to provide safety and durability. You can select our '' Top pics '' Website for Read on to know more about fiberglass Fittings pipe insulation. >>>>>>>>
Smoking tobacco using a water pipe also called as hookah, generally is viewed in a more positive light than smoking cigarettes, particularly for women, according to one of the first studies on water pipe and cigarette smoking to look at social attitudes and gender. These pipes originated in the Middle East hundreds of years ago and were popular primarily among men who used them to smoke tobacco in cafes, where they gathered and talked.

In hookah, tobacco is heated by charcoal, and the resulting smoke is passed through water filled chamber, cooling the smoke before it reaches the smoker. Some water pipe users believe that this method of smoking tobacco delivers less tar and nicotine than regular cigarette smoking and has fewer adverse health effects because of the filtering effect of the water. Especially, in these days water pipe smoking seems to be increasing among adults as well as youth. Teens who had ever tried smoking and boys were more likely to report using these pipes and youth were the least likely to report using them. It is interesting that youth reporting water pipe use perceived it to be more socially acceptable and less addictive and harmful to their health than smoking cigarettes.

These pipes of many forms are available throughout a large part of Eurasia. Several different names are associated with these pipes, and some of these refer to the construction materials from which the pipes were originally made. For example, the word hookah refers to a round storage-jar. In their basic operating principle, all of these pipes use water to cool the hot smoke and render its flavor mellower. Finally, there are some well established and experienced manufacturers of these pipes are selling these items through online For more information and details, please do not hesitate to visit their valuable website.

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.
