Steel Pipe

Steel building construction converts structural steel components into complete load-bearing structures through design, fabrication and installation. The process begins with defining project requirements and selecting a suitable structural system based on building function, load conditions, span requirements and service environment. Structural members such as columns, beams, bracing systems, secondary members and connection assemblies are then […]

Steel silos are vertical storage structures made primarily from structural or galvanized steel, typically formed as cylindrical shells with a flat or conical bottom depending on the material and discharge arrangement. They are designed for the bulk storage of dry granular and powdered materials, with the steel shell carrying the loads generated by the stored […]

Steelwork refers to fabricated structural assemblies formed by processing and assembling steel components into load-bearing structures for industrial, commercial and infrastructure projects. These assemblies are produced from structural steel members, including beams, columns, plates, channels and hollow sections, through processes such as cutting, forming, machining, welding and connection assembly according to specific project requirements. Each […]

Differences of ASTM A53 B and ASTM A106 B. ASTM A53 B covers ERW, Seamless and Galvanized steel pipe. A106 B covers only seamless steel pipe for high temperature service.

The differences between LSAW pipe and SSAW pipe. LSAW pipe welding in longitudinal, SSAW pipe welding in spiral, LSAW quality is better than SSAW.

In welded steel pipe production, ERW (Electric Resistance Welded) pipe and HFW (High-Frequency Welded) pipe are two closely related but distinct concepts. ERW refers broadly to the electric resistance welding process, which may use low, medium, or high-frequency currents to generate heat and form the weld. Within this category, HFW pipe is a specific subset […]

The differences between the seamless steel pipe and welded steel pipe, on performances, manufacturing processes, applications, sizes.

Differences between 3PE and FBE. 3PE coated steel pipe have 3 layers of FBE, corrosive, and PE layers, it has integrated advantages of FBE and PE.

API 5L line pipe (Seamless and welded pipe) of all grades have PSL1 and PSL2 two product specifications, they are different on chemical composition, manufacturing processes, mechanical strength, heat treatment, test records, traceability etc. Line pipes in API 5L PSL2 is higher than PSL1 a. PSL is the short name of product standard level. The product […]
