¿A qué debo prestar atención al comprar tubos de acero sin costura?

Seamless carbon steel pipes are steel pipes without welds that are manufactured by hot working methods such as piercing and hot rolling. If necessary, the hot-worked pipe can be further cold-worked to the required shape, size and performance.

Seamless steel pipes are widely used in the manufacture of structural parts and mechanical parts, such as seamless drill pipe, automobile transmission shafts, bicycle frames, and steel scaffolding used in construction. When saving materials and processing, steel pipes have been widely used for manufacturing.

So what should you pay attention to when buying seamless steel pipes?

① Check the product quality certificate issued by the seamless steel pipe manufacturer and the certificate number of the production license management;

②Choose the appropriate specifications, because seamless steel pipes of different specifications are used in different fields, and their functions are also different;

③Choose seamless steel pipes of different processes, because seamless steel pipes can be divided into cold-rolled and hot-rolled. Different production processes have different characteristics of the steel pipe, and naturally have different application fields;

For example, a general seamless steel pipe can exceed a certain specification only in terms of compressive strength. But as far as the plasticity of the pipeline and the acceptance of the pipeline are concerned, it will be greatly harmed.

④The seamless steel pipes of the same specification can be consulted by different manufacturers and compared repeatedly. If they are far below the average value, they cannot be purchased;

⑤ Pay attention to observation, the surface of seamless steel pipe is not allowed to have defects such as cracks, scars and folding;

⑥ The bulk purchase method of manufacturers is the first choice. If you want to wholesale seamless steel pipes, it is best to find the other party’s manufacturer directly. After all, you can still enjoy certain discounts without intermediate links, and you can also save more costs.
