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.

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.

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

Strong vapor barrier capability

Closed sell, non wicking components

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.

Hot Insulation Material

As the world moves deeper into recession, grouping is looking for structure to cut their everyday experience expenses. One of the major expenses in every household is that of forcefulness consumption. With all the appliances and gadgets men hit made, we tend to use, misuse and squander a good deal of energy. One easy way to spend forcefulness and to cut some of your bills is by ownership liquid hot exclusive the wind for longer durations in winter. Insulating liquid wind is the easiest way to achieve this cut in energy.

First of all, measure the dimensions of the liquid wind you want to insulate. If you find some leakage point, get that fixed before continuing with the hot insulation.

Once you hit checked all wind and condemned measurements, you need to end which type of detachment you should use. Whatever detachment that you select, ensure you cover as much area as you crapper so that modify that escapes is kept to a minimum. The most common hot insulation material utilised in this affectionateness is pre-formed formed detachment foam. Because of being common, you crapper easily get it for most sizes and lengths, and separate small pieces are available for spigots. In order to get the prizewinning installation, ensure that the inner diam of the foam is about equal or exclusive slightly large than the outmost diam of the pipes. This module forms a closure and so cool expose module not is stuck between the pipelines and insulation.

Upon acquiring the necessary hot insulation material, use a mild cleaning agent to remove some carbon from the pipes. Also make trusty there isn't some oil or other dampness on the outmost surface as this hinders with the installment of detachment hot insulation material. After the wind become dry, twine the foam around it carefully without leaving some conception of the pipe uncovered. Additionally, when attaching 2 formed foams at bends, it is a good idea to cut the foam at forty-five degree angles, such that they bear the whole bend and don't leave some space uncovered. Once you hit successfully put it on the pipes, twine some acrylic enter around it to ensure greater efficiency.
