Product Description

Product Description

Bend pipe

A pipe bend is a pipe fitting used to change the direction of a pipeline. It is widely used in the fields of oil, gas, liquid, and engineering bridge construction. The pipe bend is made by a complete set of bending equipment, which is mainly divided into two processes: cold bending and hot pushing.

Hot-Dip Galvanized Steel Pipe

Hot-dip galvanized steel pipes, made by dipping carbon/welded steel pipes in molten zinc, form a dense zinc layer (≥85μm) via hot-dip plating for enhanced corrosion resistance. The zinc layer bonds firmly, suitable for humid, acid/alkaline environments or long-term outdoor use.

Types include straight seam, spiral welded, large-diameter, Q195/Q235B/Q345B, various standards (British, national, American), ERW, No. 40, heavy/thick-walled/thin-walled, and powder coating galvanizing.

Specs: DN15 (1/2")~DN1200 (48"); wall thickness 0.5~20mm (sch10, sch40); length 6m/9m/12m (customizable).

Standards: ASTM A53/A53M, ISO 1127, EN 10255, AS/NZS 1579, ASME B36.10.etc

Electro-Galvanized Steel Pipe

Electro-galvanized steel pipe has a 10~25μm zinc layer via electrochemistry. Thinner coating, lower cost, weaker corrosion resistance vs hot-dip; for indoor dry/low-corrosion environments.

Types: cold-dip seamless, straight/spiral welded, large-diameter, Q195/Q235B/Q345B, British/national/American standard, scaffolding, 2/3/8/10ft, customized, 1 1/4"×5ft, forged.

Specs: DN15 (1/2")~DN150 (6"); wall thickness 2.0-4.0mm; length 6m/9m/12m (customizable).

Standards: ASTM A153, ISO 2081, EN 10143.etc

Coating thickness: ≥12μm (indoor), ≥20μm (humid, ISO 2081 C2/C3).

Round Galvanized Pipe

Circular galvanized steel pipes are round steel pipes with a zinc layer, forming anti-corrosion layers via hot-dip or electro-galvanizing. They are widely used in construction, energy, machinery, water supply and drainage, etc.

Types:hot-dip/cold-dip round, threaded, grooved, Q195/Q235B/

Q345B round, low carbon, downpipe, industrial, RMC galvanized.

Nominal diameter: hot-dip DN15 (1/2")~DN600 (24"); cold-dip DN15 (1/2")~DN150 (6").
Wall thickness: hot-dip covers Sch.20~Sch.80; cold-dip 0.8~4.0mm.
Length: 6m/9m/12m (standard), customizable.

International standards: ASTM A123, ISO 1461, EN 10346, ASTM A153, ISO 2081.etc 

Square/Rectangular Galvanized Pipe

Square/rectangular galvanized steel pipes are hollow, formed via cold bending or welding, with a zinc layer (hot-dip/electro-galvanizing) for corrosion resistance. They have square/rectangular cross-sections, widely used in building structures, machinery, furniture, vehicle manufacturing, etc.

Types include Q195/Q235B/Q345B galvanized square, hot-dip/cold-dip/welded galvanized square, 2.5×2.5 galvanized square tube.

Sectional size:

 • Square tube: 20×20mm~400×400mm (EN 10210) or 50×50mm~600×600mm (GB/T 3094); mainstream 50×50mm, 100×100mm, 200×200mm, wall thickness 1.5~16mm.

• Rectangular tube: 20×30mm~400×800mm (EN 10210) or 30×50mm~600×400mm (ASTM A500); common ratios 1:2 (e.g., 50×100mm), 1:3 (e.g., 50×150mm), wall thickness 2.0~20mm.

Wall thickness: Hot-dip 1.5~32mm; cold-dip 1.0~6.0mm.
Length: 6m/9m/12m (standard), customizable.

International standards: ASTM A500, EN 10219, ISO 1461, ASTM A153, EN 10143, EN 10210, GB/T 3094.
