Haihao Group Ships ASTM A234 WPB & A420 WPL6 Pipe Fittings to Poland
Haihao Group has completed full inspection and shipment of ASTM A234 WPB & A420 WPL6 pipe fittings for a Polish industrial piping project. This large consolidated batch combines two core carbon steel grades under ASME B16.9, covering elbows, tees, concentric and eccentric reducers, plus pipe caps, with both STD and XS wall schedules across DN15 up to DN300.
The ASTM A234 WPB & A420 WPL6 pipe fittings are separated by service requirements for the site. ASTM A234 WPB serves standard ambient and moderate temperature piping, while A420 WPL6 is selected for low-temperature service where guaranteed impact toughness is required. The ASTM A234 WPB & A420 WPL6 pipe fittings include long radius 45° and 90° elbows, 3D elbows, equal and reducing tees, concentric reducers, eccentric reducers and end caps, covering a wide range of branch, transition and termination needs.

Our QC team verified dimension, wall thickness, marking and material test certificates for every ASTM A234 WPB & A420 WPL6 pipe fittings unit before packing. All items follow ASME B16.9 forming and tolerance rules, with clear heat traceability for each heat number. Mixing two material grades in one shipment is common for European process projects, as it lets the contractor source all required butt weld fittings from one supplier instead of multiple vendors.
Poland and wider Central Europe projects often require dual-grade fitting packages for mixed temperature circuits. If you need ASME B16.9 butt weld fittings combining A234 WPB and A420 WPL6 for low and normal temperature lines, send your schedule and size list to our engineering sales team for a full quotation.
