Welding seamless steel pipe

Are you interested in welding seamless pipes from the supplier AvecGlob? Here you will find interesting information on this topic.

The nomenclature of products. Seamless pipe production process

Steel seamless pipes can be connected in various ways. The main methods are electric butt welding, friction welding, welding, resistance welding. The choice of technology depends on the operating conditions of the pipeline, the material and the technological process for the production of pipes.

The process of making seamless pipes begins with the conversion of raw materials into steel bars. In various types of rolling steels, the steel rods are formed into a solid round shape, called a preform, which is heated and pushed / pulled onto the piercing rod, resulting in a hollow tube.

Seamless pipes are manufactured in accordance with the needs of customers with regard to the size and wall thickness specifications, as well as heat treatment for more demanding applications.

Supplier — AvekGlob Company — offers at a reasonable price from the manufacturer a diverse range of seamless pipes and welded structures from them that meet the technical requirements of domestic and foreign standards. The supplier guarantees the timely delivery of products to any address specified by the consumer.

Welding technology

The choice, as usual, is based on accessibility, expediency and economy. Electric arc welding uses shielded metal arc welding and gas arc welding using tungsten non-consumable electrodes. The first method is used for thin-walled pipes, for stainless steel pipes and special alloys, as well as for increased liability pipelines that will be operated under more severe conditions. All mentioned types of electric welding require high qualification of welders.

Processes of gas arc welding and flux arc welding are used less often, since they do not differ in the stability of the results obtained.

Welding by friction and resistance gives a more predictable quality. Since these operations are performed on specialized equipment that operates with strictly assigned characteristics. The limitation of these methods is that they can be implemented only in stationary, production conditions.

Supplier — AvekGlob Company — offers to purchase various profiles and welded constructions from seamless pipes, which meet the technical standards and quality requirements. Products can be bought at a price formed on the basis of European and world standards of production. Implementation is possible in bulk and retail, for regular customers, a flexible system of discounts operates.
