Hot-Worked Pipes

Seamless hot-worked steel pipes are a type of rolled metal product with increased strength and tightness due to the absence of joints, spiral, transverse and other seams. They significantly surpass alternative welded similar items in terms of resistance to various types of impact and have a wide application profile. They are fabricated by hot working of carbon and alloy steel. The temperature at which the hot-rolled pipe is processed at the mills significantly exceeds the temperature threshold for recrystallization. It is a basis for the fabrication of cold-rolled metal products.

Due to the seamless production method and the use of high-carbon alloy steels, such products are considered as highly reliable and they meet the technical and functional requirements for use in critical applications – in the construction of infrastructure facilities, including trunk pipelines, housing and communal services and utilities, equipment for nuclear power plants, for the manufacture of elements of machines and mechanisms.

Hot-Worked Steel Pipes: Application Features

Industry

Features

Power industry

Hot-rolled steel pipes as per GOST 8732-78 are intended for operation under high pressure, they are used to create the systems for circulating the working medium in boilers and for feeding of superheated steam to turbines

Chemical

The industry application is driven by the desire to eliminate the possibility of leaks during the transportation of chemicals

Oil and gas

Drilling, casing and auxiliary pipes are used in geological exploration and operation of oil and gas wells.

Hot-rolled seamless steel pipes are also indispensable in the construction of trunk pipelines in high pressure applications, with hundreds of atmospheres.

Construction

They are used in housing and communal services, road construction, in agriculture for the fabrication of parts of metal structures: foundation piles, columns, trusses and beams, lighting poles, in the construction of scaffolds, fences, irrigation structures

Aircraft-, shipbuilding and mechanical engineering

Body, piston, hydraulic systems of aircrafts, vehicles, parts for drilling, oilfield, mining, crane equipment

In the aircraft industry, thin-walled products as per GOST 8732-78 are most in demand, since they combine maximum strength, small wall thickness and low weight.
The main requirement for pistons and cylinders is the resistance to ultra-high pressure; such a load can be only withstood by thick-walled seamless metal products (with a large wall thickness), fabricated by hot working and characterized by ultra-high strength.

Hot-rolled steel pipes of ChelPipe Group

Products of Pervouralsk New Pipe Plant (PNPP) and Chelyabinsk Pipe Rolling Plant (ChelPipe) have a wide range of schedules and their own distinctive features:

  1. Pipe diameter is in the range 32 / 550 mm with wall thickness of up to 90 mm.
  2. Fabrication of products according to the standards developed subject to the technical requirements of specific consumers.
  3. Compliance with 28 specifications, including GOST 8732-78, as well as international standards ISO 9001.
  4. Verified dimensions, the same weight and the minimum value of the curvature index of the product.
  5. Affordable price for hot rolled steel pipes (in comparison with the cost of similar products).

Hot Rolled Steel Pipes Production Technology – Main Stages:

  1. Preparation of solid steel billets (cutting, heating).
  2. Fabrication of a thick-walled sleeve on a piercing mill.
  3. Preheating in a furnace before feeding to the mill.
  4. Straining the sleeve on the mandrel at rolling mills to reduce the thickness and diameter of the wall.
  5. Improvement of the surface quality by hot finishing (reeling-in, calibration, reduction).


All processes for the fabrication of pipe-rolls start from the billet table. Here, the billets of the required length are obtained from round solid rods, by breaking them on hydraulic presses according to pre-made cuts or cutting them on the shearing press without preheating. At the piercing mill, the sleeve is rolled into a pipe of the required diameter and wall thickness in various ways.

The range of fabricated products is subject to the type of pipe-rolling equipment. The method of rolling the sleeve into the pipe characterizes the type of pipe rolling unit. At ChelPipe and PNPP, the products are fabricated at automatic, continuous, two-high (Pilger) and Assel mills.

Hot-Rolled Pipe: How to Understand Which One to Buy

To determine which pipe from the range of hot-rolled pipes to buy – the primary attention when buying is paid to the ratio of the outer diameter (D) to the wall thickness (S) and the purpose (according to GOST, Specification, DIN). ChelPipe Group produces a wide range of hot-worked (hot-rolled) seamless steel pipes for the needs of aircraft and machine building, oil and gas industry, chemical industry, construction industry, municipal services and agriculture at competitive prices. You can place an order and arrange the delivery at the website or by phone. Compliance with the state standard requirements guarantees high technical and operational characteristics and a long service life of the rolled pipes being sold. All products are supplied with quality certificates.
