3PE Coated Electric Resistance Welded Steel PipeCorrosion protection for steel structures and mechanical equipment used in marine facilities, petrochemicals, construction, and other industrial and mining enterprises, as well as for various storage tanks and conveyance pipelines. The 3PE corrosion protection longitudinal steel pipe consists of a three-layer PE coating structure: one layer of epoxy powder (FBE > 100um), one layer of adhesive (AD) 170-250um, and one layer of polyethylene (PE) 2.5-3.7mm. The three materials in the longitudinal steel pipe are integrated and firmly bonded to form an excellent corrosion-resistant layer.

Seamless steel pipes are available in diameters ranging from Φ60 to Φ1420 and wall thicknesses from 2.5 to 18mm. This is a fairly effective anti-corrosion method, typically extending the service life to 50 years. Not only does it prolong the replacement cycle of underground pipeline equipment, but it also significantly reduces costs, providing a strong contribution to national construction! 3PE anti-corrosion seamless steel pipes utilize the commonly used 3PE anti-corrosion method. Additionally, there are 2PE, 2PP, and 3PP methods, which have similar manufacturing processes but use different raw materials. The characteristic of this anti-corrosion method is its simple manufacturing process, excellent anti-corrosion effect, and low cost, making it a universally recognized anti-corrosion method in the pipeline industry!
