ASTM A53, ASTM A120 Hot Dip Galvanized Steel Pipe, 1/2 to 12IN

The hot dip galvanized steel pipeline refers to a welded pipeline with hot dip galvanized finishing on both outer and inner walls.
 
The item is commonly used to build steel structures or utilized to transfer gaseous or liquid substances.
Made in according to ASTMA53 and ASTMA120 standards, the hot dip galvanized welded steel pipeline can also be utilized to build supporting brackets for farming greenhouses.
 
⑴ Technical Specifications
★ Size Variety: 1/2″~12″ (21.3~323.8 mm).
★ Wall Thickness: 1.8~12mm.
★ Requirement: ASTM A53, ASTM A120.
★ Steel Grade: GR.B, Q195, Q235, Q345B.
★ End Complete: Plain end, thread end, with coupling.
★ Finish: Hot dip galvanized.
 
The pre-galvanized steel pipe refers to bonded tube which undergo degreasing, rust elimination, phosphorization, and drying procedures before galvanization. The treatments prior to galvanization enable the item to be conveniently plated with a zinc finish, and also ensure consistent finishing thickness, strong finish adhesion, and enhanced deterioration resistance. The per-galvanized bonded tubes are widely utilized in heat, water, and gas supply systems, farming greenhouse building and construction, steel structure construction, in addition to medium and low pressure piping system.
Our pre-galvanized steel pipe is made of superior quality steel materials, and the offered steel type consists of GR.B, Q195, Q235, and Q345B. The Q235 steel function great elongation, tensile strength, perseverance, and castability, so bonded pipelines made of this product is simple for pressing and welding. The Q345B steel offers superior mechanical properties such as excellent plasticity, weldability, and low temperature resistance, so Q345B pre-galvanized steel pipe provide marvelous efficiency in -40 ℃ or lower temperature level conditions.
 
To illustrate, we can make round, square and rectangular pipelines with minimum wall thickness of 0.4 mm. The zinc covering thickness is between 60g/m2 and 120g/m2, and the outdoors diameter ranges from 15 mm to 168.3 mm.
