API 5L L485M or X70M PSL2 concrete weight coated pipe, X70M CWC pipe

API 5L L485M or X70M PSL2 concrete weight coated pipe is shorten as L485M or X70M CWC pipe. It is API 5L L485M or X70M 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 API 5L L485M or X70M PSL2 steel pipe. API 5L L485M or X70M PSL2 concrete weight coated pipe can be immersed in a certain depth of the sea bottom, laid in the swamp, rivers and lakes.

API 5L L485M or X70M PSL2 concrete weight coated pipe, X70M CWC pipe chemical composition:

f. Unless otherwise agreed.
g.Unless otherwise agreed, the sum of the niobium, vanadium and titanium concentrations shall be≤0.15 %.
h.Unless otherwise agreed, 0.50 % maximum for copper, 0.50 % maximum for nickel, 0.50 % maximum for chromium and 0.50 % maximum for molybdenum.

API 5L L485M or X70M PSL2 concrete weight coated pipe, X70M CWC pipe mechanical properties:

The concrete coating gives added weight to API 5L L485M or X70M PSL2 concrete weight coated pipe, to provide negative buoyancy and prevent L485M or X70M CWC pipe movement due to flotation. API 5L L485M or X70M PSL2 concrete weight coated pipe can be used in swampy land with high water tables and also underwater pipelines.
