Steel-lined plastic pipe fittings (carbon steel-lined plastic pipe) inherit the advantages of steel pipes and plastic pipes, while abandoning their respective disadvantages. One of the most important contents in the design of the pipe is to reasonably determine the wall thickness of the pipe according to the use conditions and requirements, and this parameter directly affects the price / performance ratio of the product. Avoid direct sunlight, stay away from fire and heat sources, and pay attention to moisture. There are iron, plastic or wooden blind plates at the two ends of the product, or wooden boxes and soft paper packaging. The steel-lined plastic pipe can be removed before the installation of the blind plate, out of the box, the package should be installed in time after removal or out of the box, can not be placed or moved for a long time, pay attention to product insulation in low temperature and cold regions. Steel-lined plastic (tortoise shell lining—steel, mesh, plastic three-in-one) is the essence of steel-plastic composite tank series. The stencil (tortoise shell) is welded on the surface of the steel body. Polyethylene is used as the raw material, and it is integrally formed on the surface of the steel body at one time by using the spin molding process (rotation molding technology). On the surface of the steel body, it is difficult for polyethylene to leave the surface of the steel body.
Steel-lined plastic pipes are an extremely corrosion-resistant product. The lining surface of the product is flat, smooth and strong. Compared with traditional steel-lined plastic and steel-lined glass fiber reinforced plastic, it has better corrosion resistance, wear resistance, no joints, no leakage, no peeling, long life, etc. It is an ideal product for the transportation of corrosive liquids. It can be applied to automobile transportation storage tanks, pipelines, stirring tanks, low-pressure tanks, vacuum tanks, reaction kettles, ion exchange columns, neutralization tanks, dilution tanks, sink tanks, acids Washing tank, crystallization tank, electroplating tank, etc. Generally, chemical and electrolytic methods are used for pickling. Pipeline corrosion protection is only carried out by chemical pickling, which can remove scale, rust and old coatings. Sometimes it can be used as a reprocessing after sandblasting and rust removal. Although chemical cleaning can make the surface reach a certain degree of cleanliness and roughness, its anchor pattern is shallow and it is easy to cause pollution to the environment.
