Across the three links
It is a kind of three-way, which is also a kind of precast direct buried insulation pipe. It is the product of the branch of the branch to avoid the adjacent parallel pipe and increase the size and structure of the branch pipe.
Part 1, steel pipe tee 45 ° bend over
2. Polyurethane rigid foam insulation layer
3. High density polyethylene outer coating
It is used to improve the elevation of the branch pipe, cross the pipe or obstacle, and use it in conjunction with planar tee and z-type crossing pipe. It can be used to improve the treatment according to different pipe diameter. Cross tee apply pressure reaches PN2.5 adopts the seamless steel tube can be connected directly, reinforcement should be considered when using welded steel pipe, generally adopts single reinforcement to strengthen reinforcing way, reinforcement diameter is 1.5 times the wall thickness of the tee branch.
Materials: carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon, PVC, etc.
Division of production methods: crown, pressing, forging, casting, etc.
