A stainless steel liner is a protective coating made of stainless steel lining the interior of pipelines. It primarily prevents chemical reactions between the pipeline's contents and the original material, while also protecting against corrosion and wear. Widely used in industries such as petroleum, chemicals, power, food processing, and water supply, it is especially suitable for environments requiring corrosion resistance, high-temperature tolerance, and high-pressure conditions.
3PE is currently the mainstream external anti-corrosion technology for long-distance oil and gas pipelines and industrial pipelines at home and abroad. It boasts excellent anti-corrosion performance, high mechanical strength and long service life, and is widely applied in harsh service environments such as buried pipelines.
Weather-resistant epoxy powder is a thermosetting powder coating suitable for harsh outdoor environments, boasting excellent weather resistance and heavy-duty anti-corrosion performance. Its core base materials are hydrogenated bisphenol A and cycloaliphatic epoxy resin, combined with modified curing agents as well as additives such as ultraviolet absorbers and antioxidants. This formulation can effectively resist ultraviolet radiation, wind and rain erosion, and prevent coating chalking, fading and aging. The coating features high mechanical hardness and strong toughness. It can be applied via electrostatic spraying or fluidized bed dipping, achieving uniform film thickness in one coat with fast curing speed. Widely used for outdoor overhead oil and gas pipelines, steel pipelines coated with this powder can have an outdoor service life of over 30 years.
Pipeline Surfacing Welding with No Joint Coating: This process is an anti-corrosion welding technology applied in the pipeline field. Its core lies in pre-surfacing a corrosion-resistant alloy layer on the inner wall of pipe ends and other components, combined with a composite welding process. It eliminates the traditional inner-wall anti-corrosion joint coating procedure after welding, and solves the long-standing industry challenge of anti-corrosion protection for "dead-end" welds in pipelines of various diameters, especially for small-diameter and long-distance pipelines.
Erosion-Resistant Fully Surfaced Welding Pipe Fittings: Erosion-resistant fully surfaced welding pipe fittings are a type of special composite pipe fittings designed specifically for high-wear and high-impact working conditions. They adopt a double-layer structure of "ductile substrate + wear-resistant surfacing layer".
