Description:
Steel tees GOST 17376-2001 are used for pipelines for various purposes, including those controlled by regulatory authorities, at PN up to 160 MPa and temperature from -70 ° С to +450 ° С
The standard establishes general specifications for seamless welded equal and transition tees made of carbon and alloy steel.

An example of a symbol for tees of steel gost 17376-2001:

• equal bore tee execution 2, D = 426 mm, T = 10 mm from steel 20 :

Tee 426x10-20 GOST 17376-01,

• the same from steel 09G2S for pipelines controlled by regulatory authorities:
Tee P 426x10-09G2S GOST 17376-01,

• adapter tee of execution 1, D = 355.6 mm, T = 11 mm, D1 = 219.1 mm, T1 = 8 mm from steel 20:
Tee 1-355.6x11-219.1x8-20 GOST 17376-01.

Why choose us:

1. All pipe fittings are strictly implemented in accordance with the standards, accept any third-party inspection, and return service.
2. Before leaving the factory, 100% dimensional inspection, 100% spectral test, mechanical and mechanical performance test, pickling, pickling process are mainly aimed at the removal of surface grease and harmful substances, complete surface passivation to prevent oxidation. Some suppliers have not implemented ( Because the surface is not visible to the naked eye after sandblasting) annealing and solid solution (heat treatment), many goods on the market are not heat-treated. When the pipe fittings are in some cold or hot environments, the seam will slowly crack if it is not heat-treated. This process is invisible to the naked eye, surface sanding (many relatively inexpensive processes on the market), bevel ends, etc.
3. Normally, the individual weight of our company's pipe fittings is heavier than that on the market, (Ensure the back arc thickness) to avoid the parts of the same wall thickness that cannot be seen by the naked eye after the processing The pressure is guaranteed, because many suppliers choose the material to the maximum limit in order to minimize the cost.
