Chrome Moly pipe, short for chromium-molybdenum alloy steel pipe, is engineered by adding controlled amounts of chromium (Cr) and molybdenum (Mo) into the steel matrix. Chromium contributes to enhanced oxidation and corrosion resistance, while molybdenum improves overall strength, toughness, creep resistance, hardenability, and high-temperature stability. The synergy of these alloying elements makes chrome moly steel […]

CRA clad and lined pipes combine a carbon-steel load-bearing pipe with an internal corrosion-resistant alloy layer for pipelines exposed to CO₂, H₂S, chlorides and other corrosive fluids. CRA clad pipe uses an alloy layer metallurgically bonded to the backing steel, while CRA lined pipe uses a separate alloy liner mechanically fitted inside the pipe. Both […]

Stainless steel pipe added with Ni and Cr elements to provide better corrossion resistance, common use stainless steel tubes 304/L and 316/L, in ASTM A312, A213, A270 and etc.

precision stainless steel tubing is stainless tubing manufactured with tighter dimensional tolerances, cleaner internal surfaces, and more consistent straightness/ovality—so it performs predictably in critical fluid, gas, and instrumentation systems. It is widely used in ultra-clean and high-reliability environments such as semiconductor, nuclear power, and bio-pharmaceutical process lines. Where high-precision stainless steel tubing is used • […]

Octal Steel provides complete, integrated production lines for LSAW, SSAW, ERW, seamless pipe and anti-corrosion coating. All sections — from plate/coil preparation, forming and welding to NDT, beveling and 3LPE/FBE coating — are designed to work together as one system, not as separate islands of equipment. When you invest in a steel pipe plant, you […]

3LPE coated pipe (three-layer polyethylene coated pipe) is protected by a fusion-bonded epoxy primer, a copolymer adhesive and an extruded polyethylene topcoat. The coating system is applied to seamless or welded steel line pipe. The FBE primer is applied directly to the blast-cleaned and heated steel surface, creating the primary corrosion-protection interface; the adhesive provides […]
