Pipeline crossings arrangements with 3-layered ACP (PE) cases

Implementation:	2020
Project owner:	Gazprom PJS
Contractor:	Volgopromcomplect

External three-layer polyethylene coating of a special design based on extruded polyethylene usage made possible to ensure guaranteed protection of the steel casing-case Ø1620-1720mm from external influences of the environment. This coating has high physical, mechanical and adhesive properties, which makes it possible to install coated steel casings in difficult laying conditions and to operate this structure in full compliance with the requirements of the Project. These cases are used in the implementation of Projects when laying main gas pipelines Ø1420mm.
