We are committed to providing one-stop service for steel pipe products to customers around the world.
Various steel pipe external coating projects are currently implemented by centerway steel co.,ltd including single-lay er/double-layer FEB, 2PE, 3PE, 3PP, Cement mortar covering and other anti-corrosion coatings with the performed standards such as DIN30670, DIN30671, DIN30678, CAN/CSA-7245.21-M92, SY/T4013-2002, SY/TO315-97 etc
The epoxy pipe coating system is a non-invasive process which uses air to move the epoxy through the pipe, completely coating the walls as it passes through.
As the application is carried out using air, this means we can coat pipes as small as 15mm and negotiate multiple bends and tees, further reducing the need to break into the building at these points
The epoxy coating creates a barrier between the walls of the host pipe and the contents eliminating internal corrosion and helping the prevention of the growth of legionella and other micro-organisms. It also prevents leaching from lead pipes or contaminated soil.
The pipes could be carrying anything from potable water, steam, chemicals, fuels, sewage, gases, we have it covered at PLS.
