Stainless steel tee

Stainless steel tee for pipe fittings, pipe fittings.To branch pipe used in the main line.Stainless steel has such as diameter and reducing tee, equal tee to take over the end are all the same size;Reducing tee, director of the control of the same size and branch pipe to take over the size less than to take over the size of head.

The principle of

Stainless steel tee is used for a pipe fittings pipe branch.For using seamless tube manufacturing tee is usually adopted by the process has two kinds of hydraulic bulging forming and hot pressing.Stainless steel tee the hydraulic bulging is through the metal materials of axial compensation bulge out branch pipe of a forming process.The process is to use special hydraulic press, with three links within the tube billet diameter equal injection liquid, through the two horizontal side of the hydraulic cylinder synchronization of the motion of tube billet, billet after squeezed smaller volume, smaller volume of liquid with the tube billet inside the tube billet and the pressure increases, when the stainless steel tee branch pipe bulge out to the pressure, the metal material in the liquid in the cylinder and the pipe pressure under the dual role of flow along the mold cavity and the branch pipe.

Stainless steel tee hydraulic bulging process can be a forming, high production efficiency;Stainless steel tee head and shoulders of wall thickness are increased.

classification

By the hydraulic bulging process equipment for stainless steel tee tonnage is larger, the current domestic is mainly used for less than the standard of DN400 wall thickness in the manufacturing of stainless steel tee.Its applicable forming material for cold hardening tend to be relatively low low carbon steel, low alloy steel, stainless steel, including some non-ferrous metal materials, such as copper, aluminum, titanium, etc.

By manufacturing standards can be divided into the national standard, the electric standard, water standard, American standard, Germany standard, Japanese standard, the standard, etc., specific as follows: GB/T12459, GB/T13401, ASME B16.9, SH3408, SH3409, HG/T21635, DL/T 695, SY/T 0510, DIN 2615.
