Stainless threaded couplings from the manufacturer

The products are used for threaded connection of pipes for various purposes, regardless of its complexity.

The internal thread of the coupling provides ease and speed of installation, which is the main difference from welded couplings will not work.

Product Advantages

The catalog of the company "ALFA-STAR" presents several models of threaded stainless couplings, the choice should be made taking into account the installation location of the part. High-alloy steel is used for production, which provides products with maximum strength, reliability, and durability.

  • Stainless steel is resistant to corrosion, products made of it retain their strength and their parameters for a long time.
  • It can be used in pipelines for various purposes, with a variety of working environments. The manufacturing material will not be oxidized by liquid or gas.
  • Resistance to mechanical, temperature, hydraulic loads of stainless threaded couplings. They will preserve the density and tightness of the connection in extreme situations.
  • They are manufactured according to standards (GOST, TU), have a smooth surface, precisely applied thread. 

To buy threaded stainless steel couplings, contact us by mail alfa-stars@yandex.ru , via the feedback form, or call +7(812) 457-05-59, +7 (812) 244-21-41, +7 (812) 244-21-42. Our managers will answer all your questions about the price of products, delivery and payment.
