PL Flange is inseparable no matter where it is now. It can be seen in many medium and low pressure pipelines. If it is like some places where the mountains and rivers are crossed, the construction will be very difficult. At this time, it is only necessary to connect the plate flat welding flange That's it. There are also some cities that use it under the tap water supply pipeline network. PL Flange Manufacturers china As for other scopes of application, it is often used on railways.

　　The processing technology of PL Flange Manufacturers china is generally divided into five types: casting flange, cutting plate flange, large-diameter cold-rolled flange, large-diameter hot-rolled flange, and forged flange.

　　1. PL Flange Manufacturers china cast flanges are produced by smelting scrap iron pins, and the cost is low. The smelting furnaces are almost all small workshops, the material cannot be guaranteed, and the process is simple and the carcass will have pores. The quality is unstable, belongs to the low-end technology, and is gradually eliminated.

　　2. Cutting plate flanges are first cut with steel plates, which are generally steel plates of regular material. Small-diameter ones are more common, they are easier to process, the tread is relatively flat, and the cost is low. Quality can also be used, common in small-diameter and thin-type flanges. Flat welding flange.

　　3. PL Flange Manufacturers china Large-diameter cold-rolled flanges, 304 stainless steel flanges have good ductility, and stainless steel flange manufacturers generally use steel plates to cut and roll them, and the material is not good.
