Availability: in stock
Short description
Transitional steel tee 133_4x108_4, welded for a branch of a pipeline of smaller diameter to the longitudinal axis of the main line, made of low-alloy carbon steel, is used in pipelines of gas, chemical, energy and oil industries.
133_4x108_4mm GOST 17376-2001 have different diameters of the through holes of the body and neck and therefore are called transitional . Steel transition tee 133_4x108_4 mm GOST 17376-2001 is used for branching pipelines of smaller diameter to the longitudinal axis of the main line.
At domestic and foreign enterprises for the production of pipeline fittings , various methods are used for the manufacture of transition tees 133_4x108_4 mm GOST 17376-2001 :
- mold casting;
- cutting parts with a gas cutter from a pipe billet, followed by welding;
- stamping of a solid forging with subsequent drilling of holes;
- stamping from a sheet with subsequent welding;
- stamping from pipe segments.
Technical conditions of operation (application) of tees 133_4x108_4 mm are established on the basis of the results of strength tests, taking into account all external and internal power loads, properties of substances transported through the pipeline and environmental influences.
