Branch steel Steeply curved GOST 17375
Branch seamless gost 30753 and branch gost 17375
These types of bends are used in almost all areas - engineering, oil and gas, chemical industries, heavy and non-ferrous metallurgy, utilities. Seamless bend 30753 is made by a seamless method using:
- stamping;
- or pulling along the horn-shaped core is carried out.
Steel for these bends is used in two types: carbon and low alloy. Seamless bend of 90 degrees (180 ° , 60 ° , 45 ° , 30 ° ) seamless GOST 30753 is one of the most commonly used types of bends - a universal and cheap way to change the pipe direction by 180 ° , 90 ° , 60 ° , 45 ° or 30 degrees. Branch 30753 as well as branch 17375 are steeply bent pipe fittings. They are similar in technical characteristics and applications.
As a rule, the manufacture of these bends correspond to a number of parameters:
- conditional pass;
- branch wall thickness;
- diameter of the outer openings of the outlet;
- bending angle, etc.
The bent 17375 bend in accordance with the requirements operates at temperatures from -70 to +450 degrees Celsius. Technical requirements to which the elbow curved GOST 17375 meets the following:
- a steeply curved steel branch must not have cracks, gaps, or delaminations from the inside;
- various dents, delinquency, traces of elimination of defects should not affect the dimension of the pipeline part;
- relative ovality, which should have steeply curved bends, should be no more than 6%.
Bent bends made of thin-walled welded and seamless pipes are widely used in mechanical engineering, the aviation industry, when laying pipelines, in the communal sphere. Steel bends are made of the following grades of steel: 09G2S, 16GS, 17GS, 17G1S, 10G2S1, etc. However, there are steel bends that are made of steel grade 15X5M, which is resistant to heat and corrosion. Such steel bends withstand higher temperatures .
Branch GOST 17375, as well as 30753, is manufactured by UPSK in accordance with regulatory requirements, efficiently and on time. Delivery conditions can be checked with the company manager.
