If flanges are not protected, when exposed to corrosive environments or contaminated industrial atmospheres, the corrosion rate can increase rapidly. Therefore, addressing the protection of flanges against corrosion and leaks is an urgent issue that needs to be addressed.
quality PL Flange is a type of flange connection, which is a combination of "P-type flange" and "L-type flange". It combines the advantages of the two types of flanges and has high reliability and service life.
In the continuous production of modern industry, PL Flange products are affected by medium corrosion, erosion, temperature, pressure, vibration and other factors, and leakage problems will inevitably occur.
quality PL Flange products is a kind of pipe fittings, the demand is relatively large, the main function is to connect pipes and prevent leakage, it is often used in engineering construction, which requires the purchase of flanges, but how to buy.
You must know that there are so many Best PL Flange manufacturers now, which makes you very confused when choosing a flange manufacturer, and you don’t know how to choose. Today we will talk about this issue.
quality PL Flange not only saves space and weight, but more importantly, it ensures that the joints will not leak and has good sealing performance. The reduced size of the compact flange is due to the reduced diameter of the seal, which reduces the cross-section of the sealing face. Second, the quality PL Flange gasket has been replaced by a sealing ring to ensure a match of the sealing face to the sealing face. In this way, only a small amount of pressure is required to compress the sealing surfaces.
quality PL Flange products are suitable for steel pipe connections with a nominal pressure not exceeding 2.5MPa. The sealing surface of the flat welding flange can be made into three types: smooth, concave-convex and tongue-and-groove. The application of smooth flat welding flanges is large .It is mostly used in the case of moderate medium conditions, such as low-pressure non-purified compressed air and low-pressure circulating water.
china PL Flange products: It is easy to obtain materials, simple to manufacture, low in cost, and widely used; but its rigidity is poor, so it cannot be used in chemical process piping systems with supply and demand, flammable, explosive, and high vacuum requirements, and highly, extremely hazardous occasions.
