For the twenty-first year, SZTK Metallobaza No. 4 LLC has continued to work in the supply of ferrous metal products, having established itself as a reliable supplier. We give the opportunity to choose from a wide range of products the desired type of rolled metal with delivery, if the client needs it. This is quite convenient for the customer, because now there is no need to look for rental vehicles to bring the cargo to the destination if he does not have his own. Among other types of black metal products, electric pipes are quite popular with customers. This abbreviation stands for "electric welding pipes".
Production method
In the manufacture of electric welding pipes, the method of forming and welding of rolled metal is used. The diameter of such products ranges from 26.9 mm to 323.9 mm. Carbon steel or alloy steel is used as raw material, which ensures sufficient strength and flexibility of the pipe.
Pipe seams have a longitudinal or spiral pattern, which must be heat treated. Special ultrasonic inspection devices are used to control the welding points.
Cold-deformed and hot-deformed technologies are used in the production of electric pipes. Hot deformed pipes have a lower cost. Cold rolled pipes are more precise in design and are characterized by the highest level of surface quality. All longitudinal welded pipes cost less than seamless pipes.
Large batches of electric welding pipes are produced from carbon steel. They are realized either after heat treatment, or without it, depending on what the customer needs.
In the production of these products, equipment such as machines with edging configurations, special rolls (to bend metal), furnaces for heat treatment of products and welding machines are used. The technological process produces products with different diameters and sections.
Scope of application of electric welding pipes
Electric welding pipes have a very wide range of uses. They are indispensable for the installation of water and gas supply systems, as well as for oil pipelines. In the engineering and construction industry, it is also difficult to do without them. An aggressive environment is not dangerous for them, and such pipes are also able to withstand pressure up to 16 MPa. Longitudinal welded pipes are easy to operate and can serve quite a long time.
The purchase of electric welding pipes from OOO NWTK Metallobaza No. 4 is a fairly reasonable decision for customers who value their time and their money. Warehouses and offices are located in one place, so the customer does not need to spend money�
