The purpose of the pipe casing is to protect both the communication itself against possible damage and the effects of aggressive factors, and the environment in the event of a leak. In this regard, the manufacture of the casing is regulated and made by us in strict accordance with the requirements for the product.

Depending on the operating conditions and the required diameter we produce pipe casings:

  • from hot-rolled thick plate with a longitudinal welding seam on the shell and a ring butt weld
  • from joined shells of 1500-2000 mm width
  • using rolling method at permissible steel sheet thickness
  • steel grades st3sp2, st3sp5, st20, st17G1S, st17G1SU, st09G2S, and may be manufactured from the customer's raw materials
  • quality control is carried out by X-ray and ultrasonic methods

The use of steel cases is determined not only by the working environment, but also by the location of communications:

  • under highways
  • railway and tramway crossings
  • Telecommunications, electricity and water mains nearby
  • places with a high risk of pipe damage, such as at the transition to a surface location or at the entrance to a building

Kaslino Mechanical manufactures pipe cases promptly and reliably tailored to your industry, operating environment, soil characteristics, and other relevant factors. Get more information and communicate your needs by contacting the commercial department or send a request from the site.
