High-Quality Oil and Gas Steel Pipeline with 3LPE Coating 

It is an efficient method for applying epoxy powder coating to both the inner and outer surfaces of steel pipes for anti-corrosion protection.
The anti-corrosion steel pipe offers numerous advantages, including excellent coating adhesion and strong corrosion resistance, effectively protecting against the erosion of various chemical media.
The coating surface is smooth, which reduces friction resistance and improves flow efficiency.
These anti-corrosion steel pipes are widely used in petroleum and natural gas transmission pipelines, water supply and drainage systems, and many other industrial applications.

Application:

Steel pipe internal&external FBE powder coating process, with the steel pipe internal wall blasting and external wall blasting , FBE epoxy powder coating applied to the water supply for civil use.
The picture above shows the 3LPE coating production line purchased by our customer's factory in Thailand.

Internal & External FBE Powder  coating Structure Diagram
The epoxy powder is a kind of thermosetting nontoxic coating, forming the high molecular weight cross-linking structure coating after solidifying, featuring good chemical anticorrosion and higher mechanical properties. The function of epoxy powder bottom layer is to form continuous coating, providing excellent adhension by agglutinate and solidifying the steel tube surface with good  chemical resistance and cathodic disbanding resistance. The function of polymer adhesive is to agglutinate the epoxy powder before gelation, and to agglutinate the polyethylene top layer, which unites all three layers together.
