Haihao Group delivers 90 degree long radius elbows to Singapore client

Haihao Group is pleased to announce the recent shipment of precision-engineered 90 degree long radius elbows to our valued customer in Singapore. These stainless-steel fittings were manufactured to ASME standards and custom-tested to ensure a perfect fit and reliable performance in demanding piping systems.

ASTM A403 Gr WP316/316L 90 degree long radius elbows supplied by Haihao Group to Singapore client

Project Overview & Product Specifications

For this order, we supplied three types of 90 degree long radius elbows in ASTM A403 Gr WP316/316L:

2″ SCH XXS, Beveled Ends

2″ SCH XXS, Beveled Ends

4″ SCH 40S, Beveled Ends

Each elbow features a long radius bend for smooth flow transitions and is crafted from WP316/316L stainless steel. The extra-heavy (XXS) and standard (40S) wall schedules provide excellent strength and corrosion resistance in both seawater and chemical-processing environments.

Quality Assurance & Testing

Before dispatch, every elbow underwent:

Material Test Certificate (MTC) verification for chemical composition and mechanical properties

Dimensional inspection, confirming all bends, wall thicknesses, and end bevels meet ASME B16.9 tolerances

Surface examination, ensuring a clean finish free of scratches, pitting, or deformation

These steps guarantee that our ASTM A403 Gr WP316/316L elbows arrive ready for seamless installation and long-term service.
