The order quantity of SDR9 series pipe fittings is almost zero, and domestic manufacturers have not developed the injection mold. In order to ensure the order of some foreign trade SDR9 pipe fittings, most of which will include the supporting pipe fittings, our company specially develops the SDR9 pipe fittings made through the processing of ultra-thick wall pipes by lathe and multi-angle welding machine.
Technological process is: my company large caliber 1400 lines, 800 lines, modified, it can produce outer diameter less than or equal to 1400 mm, inner diameter greater than or equal to 100 mm thick wall pipe material, after the length of intercepted by lathe processing, which can realize adjust the size of the internal and external wall and part of the position, can achieve the same as the injection pipe size, processing of special size at the same time with the special thick wall pipe fittings.
