[IF] elbow, IF Bend guarantee quality, Hebei billion gold piping supplied by Hebei billion gold piping. Pipeline Manufacturing Co., Ltd. Hebei billion in gold (www.yijinguanjian.com) had been "Business League certification", please rest assured purchase through the entire network, click on the page check "Business League certification icon," the company authentication information. You can also click on the "Business League Service Icons" on this page directly contact our customer service! IF Bend used to connect two same nominal diameter pipe, so that the pipeline for 90-degree turn. IF Bend addition to carbon to the general also contain small amounts of silicon, manganese, sulfur, phosphorus, carbon use can be divided into carbon structural steel, carbon tool steels and free-cutting steel categories, carbon structural steel is divided Two steel building structural steel and machine construction methods can be divided by the open-hearth steel smelting, converter steel and electric steel; deoxidation methods can be divided by boiling steel, killed steel, semi-killed steel and special killed steel; according to carbon content can be divided into low-carbon steel, carbon steel and high carbon steel; press phosphorus, sulfur content can be divided into ordinary carbon steel carbon steel, high-quality carbon steel and high quality steel and high-grade steel IF Bend manufacturing advantages mainly in the following aspects: (1) IF IF elbow bends without the tube as raw material manufacturers, saving pipe bending equipment and tooling costs IF guarantee quality, and available at any large diameter and wall a relatively thin thickness of the elbow. (2) the blank is flat or developable surface intermediate pipe, thus cutting simple, easy to ensure accuracy, easy assembly welding. (3) For these two reasons IF Bend Hebei billion gold piping, IF Bend can shorten the manufacturing cycle, the production cost is greatly reduced. Because does not require any special equipment, especially for on-site processing of large elbow. The technology has been applied for patent.
