Cangzhou City, Long Ze Pipe Sales Co., Ltd. (Diao Yawen 0317 -8230272 18731744075) production of seamless tee, welded tee, oblique tee, reducing tee, tee insulation, corrosion tee, cross tee, carbon steel tee, stainless steel tee, alloy steel tee, etc. Three of pipe fittings, pipe fittings. Also known as pipe tee or tee fittings, tees, with the main channel to the branch pipe in place. 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, and take over the branch pipe sizes smaller than receiver in charge. Tee is used at a branch pipe fittings. For the use of seamless pipe manufacture in terms of links, now commonly used with hydraulic bulging process and hot forming two. Hot Forming: Three hot forming is greater than the diameter of the tube tee, flattening about to tee diameter size, location in the stretch to open a branch pipe hole; tube by heating, into the forming mold and into the stretch in the tube within the branch pipe dies; under the pressure of the tube is radially compressed in the radial compression process to the branch direction of metal flow and die formed under tensile branch. The whole process is compressed by the tube and the branch of the radial parts of the stretch forming process. Hydroforming links with the different is hot tee branch pipe metal from the tube to compensate for radial motion, so called 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 for low-carbon steel, alloy steel, stainless steel material; especially large diameter and wall thickness of the side links, usually in the forming process. 1 to divide 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 create criteria can be divided into national standard, standard electricity, water, standard, American standard, Germany standard, Japanese standard, the Russian standard, etc.
