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 […]

A pipe making machine is a complete production system used to manufacture welded steel pipes for oil & gas, water transmission, and structural applications. A modern steel pipe making machine line must combine forming, welding, inspection, finishing, and material handling into one coordinated process. As a pipe making machine supplier, Octal Steel provides complete line […]

Pipe coating equipment is used to prepare, heat, coat, cool and inspect steel pipes before they are released for pipeline anti-corrosion service. For large-diameter welded pipes, the equipment is not only a coating machine, but a complete production line that controls surface preparation, internal coating coverage, external coating bonding, cooling stability and final inspection. This […]

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 […]

Cryogenic liquid tanks are specially engineered storage vessels designed to hold liquefied industrial gases at extremely low temperatures while controlling heat ingress, vapor generation, and internal pressure. Large-capacity cryogenic liquid storage tanks generally use a vertical, flat-bottom cylindrical structure with an inner liquid-containing vessel, an outer enclosure, and an insulated space between them. This arrangement […]

Distribution transformers reduce medium-voltage electricity to levels suitable for buildings, industrial equipment and local distribution networks. The required capacity, voltage ratio, insulation system and cooling arrangement depend on the electrical load and the conditions at the installation site. Four common configurations are oil immersed, dry type, pad mounted and pole mounted transformers. Oil immersed and […]

A Spherical Tank is a welded steel pressure vessel designed for the storage of compressed gases and liquefied gases under controlled pressure and temperature conditions. Its pressure-retaining shell is assembled from precisely formed curved steel plates, typically supported by steel columns and bracing systems that transfer the combined loads of the vessel and its contents […]

Skid Mounted Fuel Station integrates aboveground fuel storage, unloading, pumping, metering and dispensing equipment on a common structural steel base. Instead of constructing the storage tank, transfer piping and dispenser as separate site packages, the main operating interfaces can be fabricated, connected and tested before shipment, reducing field piping work and making the station easier […]
