Different diameter pipe special equipment: in the pipeline placement ejecting device. The device includes a metal rod, top pressure device, the commutator bracket; the metal bar heating, with Jack and a metal rod is pushed out to the outside, tube wall is made of natural outwards dug out forming tee blank. Then the tube length corresponding specifications of the parts to be welded at the top the formation of tee blank on to produce the final product. In the pipeline to processing of different diameter tee joints marking and will mark penetrated.

Ordinary rubber gaskets are suitable for use on water vapor temperature below 450, and for water vapor temperature below 120, the pressure is less than 350, and the most commonly used is 5MPa, which is made of copper, aluminum, stainless steel, 10 stainless steel, stainless steel, stainless steel, stainless steel, stainless steel, stainless steel, stainless steel, stainless steel.

Three way pipe fitting processing method to adapt to different specifications of pipe diameter on the three pipe fitting processing; its special processing equipment, the structure is simple, low cost, manufacturing different diameter of the three way pipe does not need additional injection molding machine and injection mold, can reduce the production cost of such pipe, raise production efficiency.

And a thin steel strip and asbestos band together winding and winding gasket. High pressure gasket and sealing surface of the contact width is very narrow (line contact), smooth processing surface and the gasket sealing degree is higher. Different diameter flange sealing surface of the type has three: planar sealing surface for the pressure is not high, medium, and is non-toxic occasions; uneven sealing surface for applications to pressure slightly higher; tongue and groove sealing surface for in flammable, explosive, toxic medium and high pressure situations. Gasket is a kind of can produce plastic deformation, and has a certain strength of the material of the circular ring.
