Solutions for Your Industry, Ready for Your Choice
erw black steel pipe also known as circular welded steel pipe, is a straight seam welded steel pipe made from hot-rolled or cold-rolled steel strips through continuous cold bending and high-frequency welding. It is currently the most produced and widely used economical pipe material.Widely used in structural support, fluid transportation, machinery manufacturing, construction, photovoltaics, guardrails, greenhouses, pipelines and other fields.
ASTM A501 Grade B ERW Structural Tubing
ASTM A501 is a standard for hot-formed shaped welded/seamless carbon structural steel pipes, divided into grades A, B, and C. It has good weldability, moderate cost, and is widely used in construction and general structures.
JIS G 3101 SS400 Carbon Steel Pipe
JIS G 3101 This Standard specifies the hot rolled steels and hot extruded sections used for general structure such as bridges, ships, rolling stocks and other structures (hereafter referred to as "steel product"). The core steel grades include SS330, SS400, SS490, and SS540, with product forms covering steel plates, steel strips, structural steel, and bars.
EN 10217-2 focuses on Electric welded non‑alloy and alloy steel tubes with specified elevated temperature properties, with P195GH/P235GH/P265GH/16Mo3 as the core steel grades. It meets different safety requirements through TC1/TC2 classification and is the core European standard for selecting high-temperature pipelines in power plants, chemical, and boiler industries. It complements EN 10216-2 (seamless steel pipes) and covers the high-temperature pressure requirements of welded processes.
EN 10217-1 Non-Alloy Steel Pipes
EN 10217-1: Non-alloy welded steel pipes for pressure purposes at room temperature, divided into two quality grades, TR1/TR2, with a total of six core steel grades. Suitable for high-frequency welding (ERW) and submerged arc welding (SAW) processes, meeting the strength, plasticity, and weldability requirements for pressure applications at normal temperature.
ASTM A795 GR.B CARBON STEEL PIPE
ASTM A795 is the standard specification for black and hot-dipped galvanized, welded, or seamless steel pipes designed specifically for fire protection systems (fire mains, sprinklers, standpipes).The pipe ensures reliable performance for water, air, and gas transport in fire safety applications.
EN 10219 scaffolding tubes are a global mainstream choice due to their standardization and high adaptability, with applications across construction, infrastructure, industrial, and other sectors. The surface treatment is centered on hot-dip galvanizing, and other protective methods can be flexibly combined according to environmental and cost requirements to ensure safety and durability.
