Cathay Pacific Pipeline Equipment Co., Ltd. specializes in producing steel of high, medium, low, carbon steel, alloy steel and austenitic stainless steel elbows, flanges, tees, reducers, head, elbow, forged for intubation and threaded fittings and other pipe fittings. All products are American Standard ASME (ANSI), German standard DIN, Japanese standard JIS, Chinese GB / T, JB, SH, HG criteria such as production, but also according to customer special variety of hard, non-standard, thick Wall series pipe fittings. The basic process is carbon steel elbow: First welding a polygonal cross-sectional polygonal ring shell or both ends closed polygonal fan shells, washed over the internal pressure of the media, applying less pressure, under pressure, including the role of the cross-sectional polygon becoming round, eventually becoming a circular ring shell. Spot welded carbon steel elbow as needed, can be cut into a circular ring shell 4 90 ○ 60 ○ elbow or six elbow bends or other specifications, the process for the manufacture of elbow and elbow in diameter Any size larger than the inner diameter of carbon steel welded elbow elbow greater than 1.5, is the ideal way to present the manufacture of large steel elbow. The advantage of the carbon steel elbow making process mainly in the following aspects: (1) without the tube as raw materials, saving pipe equipment and tooling costs, and get arbitrarily large diameter and wall thickness of relatively thin carbon Steel elbow. (2) the blank is flat or developable surface, thus cutting simple, easy to ensure the accuracy of Hebei steel welded elbow manufacturers, easy assembly welding. (3) For these two reasons, Cangzhou steel welded elbow, you can shorten the manufacturing cycle, the production cost is greatly reduced. Because does not require any special equipment, especially for on-site machining of large steel elbow. (4) carbon steel elbow for carbon steel welded pipe lines Cangzhou elbow, carbon steel welded elbow oil, gas, chemicals, utilities, construction and boiler industry, please look for the pipeline by Hebei Hebei Cathay Cathay available.
