ASME B16.9 WPL6 Tee 6 Inch SCHXXS Delivered to Indonesia | Haihao Group
Haihao Group has completed the manufacturing, non-destructive evaluation, and sea-freight packing for a batch of high-pressure pipe fittings delivered to an Indonesian cryogenic processing facility. The shipment features heavy-wall 6-inch equal tees manufactured to stringent low-temperature impact standards.
Order Technical Profile
Designed for sub-zero operating environments and severe line pressure, the delivered fittings met the following precise parameters:
Product Description: Equal Butt-Weld Tee
Nominal Pipe Size: 6″ (DN150)
Wall Thickness / Schedule: SCH XXS (Extra Extra Strong)
Material Grade: ASTM A420 Grade WPL6
Manufacturing Standard: ASME B16.9
Engineering Challenges: Forming Heavy-Wall SCHXXS Fittings
ASME B16.9 WPL6 tee 6 inch SCHXXS heavy wall equal tee for Indonesian low temperature project
Manufacturing a 6-inch 6 inch SCHXXS tee requires exceptional press tonnage and precise temperature control during hot extrusion. With wall thicknesses exceeding standard schedules, ensuring uniform metal flow across the tee branch crotch is critical to prevent wall-thinning and localized stress concentrations.
Every ASME B16.9 WPL6 tee in this order underwent automated CNC end-beveling to guarantee precise weld prep angles (37.5° ± 2.5° with a 1.6mm root face). This clean bevel geometry accelerates field installation during high-pressure tie-ins, reducing field welding rework rates for our Indonesian client.
Material Excellence: Low-Temp Impact Toughness of ASTM A420 WPL6
Under cryogenic or low-temperature operational conditions (down to -45°C / -50°F), standard carbon steels risk brittle fracture. The ASTM A420 WPL6 pipe fitting specification guarantees Charpy V-Notch impact energy performance under sub-zero temperatures:
Normalized Heat Treatment: The tees were subjected to full normalizing and tempering cycles to refine the ferrite-pearlite grain structure.
Sub-Zero Impact Testing: Impact energy values comfortably exceeded client design standards at -45°C, ensuring high toughness during pressure spikes or sudden thermal shifts.
100% NDT Coverage: Ultrasonic Testing (UT) and Magnetic Particle Testing (MT) were applied to verify the structural integrity across the entire fitting body.
As a trusted butt weld SCH XXS tee supplier, Haihao Group provides complete low-temperature piping packages including ASTM A420 WPL6 elbows, reducers, caps, and matching ASTM A350 LF2 flanges under certified ISO 9001 and PED 2014/68/EU quality frameworks.
Protective Coating & Global Logistics
To safeguard the machined bevels and rust-sensitive material during maritime transit to Southeast Asia, each ASME B16.9 WPL6 tee was coated with transparent anti-corrosion varnish and packed in heavy-duty export wooden cases with moisture-proof linings.
