City Bronze Pipe Sales Co., Ltd. (Diaoya Wen 0317 -5,128,359 18,731,744,075) the production of seamless links, welding links, oblique tee, reducing tee, tee insulation, corrosion tee, cross tee, carbon steel tee, stainless steel tee, steel links and so on. Three of pipe fittings, pipe fittings. Also known as pipe tee or tee fittings, tees, with a branch pipe to be in charge of Road Department. Links with other trails and reducer of points, such as Tee receiver end are the same size; Reducing the tee to take over charge of the same size, while the branch in charge of a receiver to take over smaller than size. Tee is used at a branch pipe fittings. Tee for the use of seamless pipe manufacturing, at present there are usually used in hydraulic bulging process and hot forming two. Hot forming: Three hot forming links is greater than the diameter of the tube, flattening about to tee diameter size, position in the stretch to open a branch pipe hole; tube by heating, into the forming mold and within the tube into the stretch in the branch pipe dies; the tube is under pressure, radial compression, radial compression in the course of the direction of metal flow to the branch and die formed under the tensile branch. The whole process is the radial compression and tube branch and forming part of the drawing process. Links with different hydraulic bulging is hot tee branch pipe is metal tube to compensate for the radial motion, so also known as radial compensation process. As a result of heating to suppress links, materials, equipment needed for forming the tonnage reduction. Hot links to the wide adaptability of materials suitable for low-carbon steel, alloy steel, stainless steel material; especially large diameter and wall thickness of the side links, usually the forming process. 1 divided by the material of carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum, plastic, argon Ge Lek, ppc, etc. (2) the production method can be divided into the top system, pressing, forging, casting and so on. 3 to manufacturing standards can be divided into national standard, standard electric, water standard, American standard, German standard, Japanese standard, the Russian standard, etc.
