* Technical specification included in the Registry of welded steel structures, couplings for stabilizing units and repair couplings recommended for use at Gazprom sites.

Couplings for stabilizing units are designed to provide tight connection of inlet and outlet pipeline sections at launching and receiving points for cleaning and diagnostics equipment. Available climate designs are U and UKhL, diameters up to 1420 mm, operating pressure rating for main lines is up to 11.8 MPa and for upstream pipelines it is up to 24 MPa. 

Reference example of M1 type stabilizing coupling, OD 1020 mm, connected pipe WT 22.2 mm, strength class K60, operating pressure 9.8 MPa, service factor m=0.75 and climate design U:

М1-1020(22,2К60)-9,8-0,75-У
