ASTM A790 S32750 Pickling Annealing Surface Duplex Steel Pipe
ASTM A790 S32750 Duplex Steel Welded Pipe Pickling&Annealing Surface
Welded Pipe:
A welded pipe is manufactured from the longitudinal welding of steel. The welding process for ERW pipes is continuous as opposed to the welding of distinct sections at intervals. ERW process uses steel coil as feedstock.
Welded Pipe Specification:
1. Material Grade: S32205 , S31803 , S32304 , S32750, 2205 , 2507 etc
2. Outer Diameter: 10.3mm-1219mm
Wall Thickness: 1.24mm-59.54mm
3. Length: Normally fixed length 6m, can as per customer’s requirement
4. Standard: ASTM A789 ; ASTM A790 ect .
5. Process Method: ERW, EFW, etc
