Manufacture of stainless steel tubes

Are you interested in the production of rolled stainless steel pipes from the supplier company AvecGlob? Here you will find the necessary information on this topic.

Development of methods for the production of pipes of stainless steels

Rolling previously was the only method used to produce stainless steel pipes for industrial use. Rolling technology included lengthy procedures: the folded stripes of the sheet were gradually formed into a circular cross section using funnel-shaped rolls. Then, from these rolled strips, a continuous joint was made by welding, forming a pipe.

Modern pipe production includes not only rolling, but also extrusion. The process proceeds in a continuous cycle on horizontal pipe presses. Welding is not required

Modern process of production of stainless steel pipes

First of all, rolled products from rolled stainless steel are checked for quality, and cut into size. Then they are fed into a continuous-type continuous press. The preforms pass through a predetermined number of spinnerets / matrices that sequentially form the outer diameter and wall thickness of the tubular blank, in accordance with the desired size. In the press, the strip gradually turns into a tubular shape.

Next, a welding machine is used to weld the edges of the strip strip using the TIG welding process. Waste and internal welding beads are removed by special equipment.

Supplier — AvekGlob Company — offers to buy stainless steel pipes in the assortment. Products can be bought at a price formed on the basis of European and world standards. Implementation is possible in bulk and retail, for regular customers, a flexible system of discounts operates.

Cleaning and heating

Stainless steel rolling tubes made in this way are cut to the required length, depending on the industrial demand. The products are then cleaned to remove contaminants. In addition, for heat treatment, heat treatment is performed, which eliminates stresses arising from welding processes. Heat treatment is carried out in a continuous oven. The furnace is equipped with temperature recorders and controllers. After the heat treatment process, the tubes are straightened and etched to remove scale.

Calibration

In some cases, the required size can not be obtained directly on the press. The cold calibration process is used to obtain the desired size. In the process of deformation, the pipes are covered with oxalic and / or soap solution. This does not act as a lubricant to reduce friction when working in cold deformation mode.

Finishing

It is the production of markings on finished pipes. The pipe is marked with the marking of the material and dimensions. Finished pipes can be tested for their mechanical properties.

Supplier — AvekGlob Company — offers various types of rolled stainless pipes, which meets the standards of domestic and foreign standards. The products are offered at affordable prices from the manufacturer. The supplier guarantees the timely delivery of products to any address specified by the consumer.
