Polyurethane insulated steel pipe  is suitable for conveying various things within the range of -50℃ to 150℃. It is widely used in centralized heating, cooling, hot oil transportation, as well as insulation and cooling projects in greenhouse, cold storage, coal mining, petrochemical, and other industries. After years of practical application, it has been widely recognized by users as an environmentally friendly and energy-saving insulation material and becoming the main stream for building insulation future. One of the reason why is polyurethane thermal insulation steel pipe becoming important is that it has good thermal insulation performance, and the heat loss is only 25% of the pipe material. Long-term operation can save a lot of energy. Polyurethane has strong waterproof and corrosion resistance. It does not need to be attached to the pipe trench and can be directly buried in the ground or water. The construction is simple and fast, and the overall cost is low. Moreover, it al...

3PE steel pipe   is 3-layer structure polyethylene coating anti-corrosion steel pipe. Its bottom layer is epoxy powder coating, the core layer is copolymerized adhesive with branched functional groups, and the face layer is high-density polyethylene coating. 3PE steel pipe is a new anti-corrosion steel pipe coating produced by combining the European 2PE anti-corrosion coating and the epoxy powder anti-corrosion steel pipe coating (FBE) used in North America. It has been recognized and used all over the world over decade.  3PE steel pipe has high impermeability and mechanical properties of epoxy resin and polyethylene materials, which makes it is recognized the best effect and performance anti-corrosion coating pipeline, and applied in lots project. Changsha Xiangjia Metal Materical Co., Ltd.  specializing in the production and sales of carbon steel pipes, alloy pipes, stainless steel pipes, etc., welcome to call us for consultation.

Steel pipe  are used for fluid and gas transportation. Pipelines are often buried in the ground or underwater or overhead. Therefore, corrosion resistance of steel pipes is very important. Following, let's take a look at the anti-corrosion process of spiral pipe. According to the application and anti-corrosion process, the pipeline anti-corrosion method divided into 3 types: IPN8710 anti-corrosion and epoxy coal tar pitch anti-corrosion steel pipes are used in tap water supply and water pipelines, most of them are adopt outer epoxy coal tar anti-corrosion and inner IPN8710 anti-corrosion technology. 3PE anti-corrosion steel pipes and TPEP anti-corrosion steel pipes are generally used for gas transmission and tap water transmission. These two anti-corrosion methods have the best performance, but the cost is high. Plastic-coated steel pipe is the most widely used anti-corrosion process at present. The application fields include water supply and drainage, fire sprinkler and mining, wi...

There are types of corrosive media in the anti-corrosion   spiral steel pipe , such as acid, alkali, salt, oxidant and water vapor. The coating must be chemically inert and resistant to acid, alkali and salt corrosion. Primer of anti-corrosion spiral steel pipe: It is composed of polyurethane polyethylene, modified epoxy resin, non-toxic anti-rust pigments and fillers, additives, etc. It is cured at room temperature to form an interpenetrating network, the coating film structure is dense, also they are anti-acid, alkali, salt, and anti-rust. Topcoat of anti-corrosion spiral steel pipe: It is composed of epoxy, rubber resin modification, non-toxic anti-rust pigments and fillers, and additives. They has excellent chemical resistance, non-toxic, anti-microbial erosion.

Since  SSAW steel pipe  are stocked outdoors, most of them are buried in the ground during use, so they are easy to corrode and rust. But once the pipeline is corroded, it will cause oil and gas leakage, which will not only interrupt the transportation, but also pollute the environment or may cause fire. So in order to ensure the smooth flow of the pipeline, the spiral pipes must have strong corrosion resistance. Reasons for the rust of the SSAW steel pipe. 1. Anti-corrosion failure. It is necessary to do a good job of anti-corrosion work or use anti-corrosion SSAW steel pipe directly. The reason why the pipeline is corroded is because the anti-corrosion layer of the pipeline is damaged.    2. The influence of external conditions. The main thing is to check the characteristics and temperature of the medium around the pipe, and whether the medium around the pipe is corrosive. If it is a long-distance pipeline, the nature of the soil environment is more complicated. In...
