The PVC anti corrosion tapes have the characteristic of weather resistance and anti-corrosion so this kind of the PVC corrosion resistant tapes is widely used for corrosion protection and ground pipes like air duct,water pipe and oil pipe line.
CORROSION RESISTANCE I.P.S. Pressure PVC pipe is unaffected by electrolytic or galvanic corrosion, or any known corrosive soil or water condition. You don’t have to worry about tuberculation, or the need for costly lining, wrapping, coating, or
Corrosion on pipes and fittings It is rather common for corrosion to gather on fittings and water pipes. Overall corrosion is generally considered a maintenance type of item. However, there are times that the corrosion will lead to leaking. ( READ MORE ABOUT CORROSION AND LEAKS)

PVC is immune to internal corrosion, so no liners are needed to maintain water quality and flow characteristics. PVC is immune to external corrosion, so no coatings, plastic encasement[s], or hodic protection[s] are needed.
pipe. For PVC pipe, the standard C value is 150. New HDPE pipe uses a C value of 140, but with use and corrosion a lower value is typically used. For HDPE pipe, a range of C values between 150 and 160 is typical. Tables A.1 and A.2 show friction loss data
6/6/2017· PVC or polyvinyl chloride pluing pipe has essentially eliminated corrosion in pluing supply and drain lines, but plenty of homes still have old galvanized pipe. Copper isn’t immune from corrosion, either, but it’s sometimes easier to spot than corrosion on galvanized metal.
9/11/· In addition, vinyl jacketing often holds the water condensed at the cold pipe surface, producing a much greater threat of exterior pipe corrosion. The threat of insulation failure is greatest in smaller diameter piping due to its inherently lesser wall thickness coined with generally thinner insulation applied.
Corrosion is a major cause of water main breaks, and PVC Pipes boast the lowest failure rate when compared to alternate piping materials. The major finding of a recent study 1 is that PVC Pipe has the lowest overall failure rate when compared to cast iron, ductile iron,

Microbiologically influenced corrosion (MIC) is, by far, the most severe and threatening form of corrosion to HVAC piping and fire protection systems. It is caused by the presence of various microbiological agents under specific environmental conditions and can in some cases result in an advanced and widespread failure of entire piping systems within only a few years.
29/3/· CPVC pipe has all the benefits of PVC pipe, plus the added chlorine gives it a higher heat resistance. It is also rated for drinking water, and is flexible, fire resistant, and well insulated to prevent energy loss for either hot or cold water.
hodic protection (CP) is by far the best way to stop corrosion on pipelines. It uses impressed currents from a fixed anode to interfere with the electrical circuit in the corrosion cell. It is 100 percent effective against most forms of external pipe corrosion.
The political landscape for utility managers is changing as sink holes, plaque cities and boiling orders to customers become commonplace. Elected officials are also feeling the pinch with limited funds, increasing operational costs and the need to understand and explain corrosion issues to their rate base. It is in this new public water climate that better pipe selection material decision Puhui Pipe manufacturer in China
The usual length of a pipe section is 12 ft, but lengths up to 20 ft can be obtained. Cast iron pipe is made in several thickness classes for various pressures up to a maximum of 350 psi. Cast-iron pipes are usually dipped in a bituminous compound for protection against corrosion and to improve their hydraulic qualities; larger sizes may be provided with a lining of cement mortar.
However, corrosion is an issue in steam-condensate pipes, and many engineers specify schedule 80 HDPE pipe simply because it takes about twice as long to rust through as schedule 40 pipe. If amines (commonly cyclohexylamine, morpholine, or diethylethanolamine (DEAE) are fed properly to neutralize condensate pipe pH, condensate pipes can last the life of the building.
Until recently, the pipe typically used was a butt-fused thermoplastic pipe, which had to be pre-asseled on an adjacent right-of-way, and then pulled as a continuous length of pipe. With the Bulldog system, PVC pipe can now be installed one joint at a time during the pullback operation.
hodic protection (CP) is a method to control corrosion by using a direct electrical current which neutralizes external corrosion typically associated with a metal pipe. It is generally used when a pipeline is buried underground or in water.
Water is trapped - The very nature of the supports allows water to be held in contact with the painted pipe surface as well as the paint on the support element. 2. The paint system fails - Even if the paint on the pipe and support beam are perfect, the paint system is designed for atmospheric exposure and not immersion service.
