City Takizawa pipeline Sales Co., Ltd. (Diao Yawen :0317-8230272 18731744075) the production of seamless three links, three links butt, oblique three, reducing tees, holding three links, anti-corrosion three direct links across the three links, carbon steel three links, stainless steel tee, tee and other alloy steel. Three links of pipe fittings, pipe connections. Also known as pipe three or tee, tee, with the main channel you want to branch office. There are points of equal diameter and Reducing three links, such as the takeover end of the Tee are the same size; Reducing the three-way competent to take over the same size, while the branch took over the size of less than competent take over the size. Three links is for the pipeline branch at a pipe fitting. In terms of the three links of seamless pipe manufacturing, the process usually used hydraulic bulging and hot forming two. Hot forming: the three-way hot forming is greater than three links, the diameter of the tube, crushed to about the size of the three-way diameter, open a hole in the stretch manifold parts; tube by heating, into the forming die and loaded in the tube stretching manifold die; tube under pressure, radial compression and radial compression process flow and the formation of a branch pipe die tensile metal branch pipe direction. The whole process is forming the radial compression of the tube and manifold parts of the drawing process. Hydraulic bulging tee, hot pressing three links-branch tube metal is compensated by the radial movement of the tube, also known as radial compensation process. Suppress the three links, the material forming the tonnage of the equipment needed to reduce by heating. Hot pressing three links to a wide adaptability of materials, applicable to low-carbon steel, alloy steel, stainless steel material; especially large diameter and wall thick side three links, usually forming process. A material divided carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum, plastic, argon Ge Lek, ppc, etc.. (2) the division of production methods can be divided into top system, pressing, forging, casting, etc.. 3 GB, standard electric, water standard, American standard, German standard, Japanese standard, the Russian standard, such as the division of manufacturing standards can be divided into
