The 3LPE coated seamless steel pipes ensures long-term reliability in extreme environments due to its excellent corrosion resistance and wear resistance. Its three-layer structure consists of: fusion-bonded epoxy (FBE), copolymer adhesive, and high-density polyethylene outer sheath. This composite structure endows the pipeline with advantages such as corrosion resistance, damage resistance, and adaptability to complex working conditions, making it widely used in fields such as oil and gas transportation and chemical facilities.

Grooved Couplings are commonly used components in piping systems, designed for the quick and convenient connection of pipes without the need for welding or bolted connections. They ensure a reliable pipe connection through a groove-based connection structure and a sealing ring, making them widely ap

The pickling process for stainless steel pipes is used to remove oxide scales, rust, oil stains, iron oxides, and other impurities from the surface of the pipes, thereby making the surface smooth, improving corrosion resistance, and enhancing welding performance. The pickling process is typically ca

The 3LPE coating (Three-Layer Polyethylene Coating) is a three-layer coating system primarily used for corrosion protection of pipelines. Its functions can be summarized as follows:Corrosion Protection:The main function of the 3LPE coating is to protect the pipeline from corrosion caused by external

"Hot-dip galvanizing" and "pre-galvanizing" are both galvanizing treatment methods for metal surface corrosion protection, but their processes and applications are different: 1. Hot-dip galvanizing:Process: The steel is immersed in molten zinc liquid (usually at a temperature of about 450°C) to reac

The "stainless steel" in stainless steel pipes refers to a type of steel that has excellent corrosion resistance and is resistant to oxidation and rusting. This steel is primarily composed of iron, carbon, and at least 10.5% chromium. Chromium is the key alloying element responsible for the corrosio
