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 […]

Steel wire rope is a load-bearing rope made from multiple high-tensile steel wires. The wires are twisted into strands, and the strands are laid around a central core to form the finished rope. Depending on the working condition, it can be supplied in carbon steel, galvanized steel, 304 stainless steel, 316 stainless steel, or high-tensile […]

Cone crushers are used after primary crushing when the production line needs controlled particle size, stable capacity and better aggregate shape. In quarry, mining and aggregate production, the key selection points are not only machine price or motor power. A suitable cone crusher should match the feed size, material hardness, crushing stage, chamber type, CSS, […]

A jaw crusher is a primary crushing machine used to break large rock, ore, concrete, and similar feed into a smaller size before secondary crushing or screening. Its crushing action is based on compression: one jaw remains fixed, while the other moves through an eccentric-driven motion and crushes the material inside a V-shaped chamber. That […]

Product Overview Rock crusher is equipment used to reduce blasted stone, quarry feed, or recycled hard material into controlled sizes for aggregate production and sand production lines. For buyers, the key point is whether the equipment can match the feed size, target output, line layout, and total operating cost, including wear parts and downstream matching. […]

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 […]

3LPP coated pipe (Three-Layer Polypropylene) is produced as an external coating system consisting of a fusion-bonded epoxy (FBE) primer, a copolymer adhesive, and an extruded polypropylene outer layer. The process includes preparing the surface of welded or seamless steel line pipe, applying the FBE primer, adding the copolymer adhesive within the qualified bonding window, and […]

API 650 tanks are vertical, cylindrical, aboveground welded tanks built with a fully supported bottom for the storage of crude oil, refined fuels, water, wastewater and other non-refrigerated liquids. The tank is assembled as a complete structure consisting of the bottom, shell courses, roof, nozzles, manways, reinforcement plates, wind girders, access systems and operating accessories. […]
