Welded API 5L L290M or X42M PSL2 concrete weight coated pipe, X42M CWC pipe

API 5L L290M or X42M PSL2 steel pipe is thermomechanical rolled or thermomechanical formed welded pipe for pipe line construction in oil, gas and water transport. API 5L L290M or X42M PSL2 concrete weight coated pipe is also know as API 5L L290M or X42M PSL2 CWC pipe. It is API 5L L290M or X42M PSL2 steel pipe external with concrete weight coating, which is mixed with cement, aggregates, reinforced steel mesh and water, to provide the strong downward force protection or a negative buoyancy for the pipelines. Welded API 5L L290M or X42M PSL2 concrete weight coated pipe can be immersed in a certain depth of the sea bottom, laid in the swamp, rivers and lakes.

Welded API 5L L290M or X42M PSL2 concrete weight coated pipe, X42M CWC pipe chemical composition:

e. Unless otherwise agreed, 0.50 % maximum for copper, 0.30 % maximum for nickel, 0.30 % maximum for chromium and 0.15 % maximum for molybdenum.

Welded API 5L L290M or X42M PSL2 concrete weight coated pipe, X42M CWC pipe mechanical properties:

The concrete weight coating is applied to API 5L L290M or X42M PSL2 concrete weight coated pipe to provide negative buoyancy and prevent API 5L L290M or X42M PSL2 steel pipe movement due to flotation in swampy land with high water tables and also underwater pipelines.
