Are you interested in TU 14−3Р-50−2001 from the supplier — Electrovek-Steel company? At us you will find only the checked up information on the given subject
The company Electrovek-steel offers to purchase at an affordable price from the manufacturer of steel seamless pipes, the production of which is carried out in accordance with technical standards TU 14-ZR-50 -2001. The supplier ensures timely delivery of products to any point specified by the consumer.
TU 14-ЗР-50 -2001 apply to seamless steel pipes, hot-rolled thick-walled from cast ingot, intended for the manufacture of electric motor housings, rollers of roller tables and other non-conforming products of similar purpose. The workpiece for the pipes are cast ingots, manufactured according to the documentation of the pipe manufacturer.
Pipes made of steel seamless hot-rolled thick-walled are available in lengths from 4 to 11.9 m. Up to 20% of pipes of smaller lengths, but not less than 1.5 m, are allowed.
Depending on the quality of the pipes, the following groups should be made:
A — with the normalization of mechanical properties of steels St2cn, St4cn, Stssp, Stbsp, 38XA, 40X, strength groups C and D;
B — with the normalization of mechanical properties and chemical composition of steels of grades 10, 20, 35.45 in accordance with GOST 1050; St2sp, St4sp, St5sp, Stbsp in accordance with GOST 380; 38ХА, 40Х according to GOST 4543.
In steels with a chemical composition according to GOST 1050, the residual content of chromium and nickel is allowed not more than 0.40% and copper is not more than 0.30%; in steels with a chemical composition according to GOST 380, the residual content of chromium and nickel is not more than 0.35% and Copper is not more than 0.40%, in steels with the chemical composition according to GOST 4543, the residual nickel content is not more than 0.40% and copper is not more than 0.30%.
To buy the rolled steel seamless hot-rolled thick-walled pipes from the cast ingot, which are intended for the manufacture of the housings of electric motors, rollers of roller tables and the like, offers the company Elektrovek-steel. Products are sold at affordable prices from manufacturers. The supplier provides immediate delivery of the rental at any address specified by the client.
The strength characteristics of steel seamless hot-rolled thick-walled pipes made of steel ingot according to the norms of TU 14-ZR-50 -2001 should be within the following limits:
|For pipes with wall thickness|
|Up to 45 mm||45 mm and more|
|(Kgf / mm -)||(Kgf / mm «)||(Kgf / mm -)||(Kgf / mm -)|
|Not less than|
|NOTE The yield strength is determined at the request of the consumer.|
Of the special requirements are the following:
On the surface of pipes, spiral filaments and cracks are not allowed. Small foils, dents, risks, flaws, sunsets and other defects of rolling origin are allowed, if they do not lead to the wall thickness for the minimum permissible values;
Local defects on the outer surface of pipes, which take out the wall thickness beyond the minimum allowable value, are subjected to cutting with subsequent welding by the pipe manufacturer;
Repair and removal of metal defects, caused by the nature of the cast ingot and opened during machining, produces a pipe consumer.
The ends of the pipes are cut by the fire method or by a saw of hot cutting. When trimming pipes with a fire method, the allowance along the length of the pipe must be at least 20 mm for each cut.
To buy steel seamless pipes made according to technical specifications TU 14-ЗР-50 -2001, the company Electrovek-steel offers. Effective prices are from the manufacturer. The supplier guarantees the prompt delivery of products to any point specified by the consumer.
