Haihao Group Delivers Full Range of A234 WPB Seamless Butt Weld Fittings to Pakistan Client

Sourcing mixed batches of butt weld fittings across multiple sizes and schedules often creates lead time and consistency risks for pipeline construction projects in Pakistan. Haihao Group has completed fabrication, inspection and shipment of a complete package of A234 WPB ASME B16.9 fitting components for a Pakistani industrial client, covering reducers, equal tees and reducing tees to match the full layout of their process piping system.

The reducer portfolio includes both concentric and eccentric designs, all seamless and machined with beveled ends ready for field butt welding. Sizes span from 4″×3″ SCH40 up to large-bore 24″×20″ STD units, with intermediate 6″×4″, 8″×6″ and 18″×16″ options available in SCH40 and STD wall schedules. Each A234 WPB ASME B16.9 fitting in the reducer range is formed from wrought A234 WPB carbon steel, a grade widely specified for midstream and utility piping across South Asia. Eccentric reducers are engineered to prevent liquid pooling in horizontal pipe runs, while concentric versions deliver smooth, low-turbulence diameter transitions in vertical lines.

Complementing the reducers, the tee selection covers equal and reducing configurations to support all branch connection points across the pipeline network. Reducing tees range from 2″×1″ up to 24″×12″, with wall thickness combinations including SCH40, SCH80, SCH160 and STD to align with main and branch line pressure ratings. Equal tees are supplied in sizes from 2″ through 24″ in matching schedules. Every A234 WPB ASME B16.9 fitting undergoes precision end machining to ensure consistent bevel geometry, reducing on-site fit-up time and rework for Pakistani construction teams.

All fittings receive shot blast surface preparation to deliver a clean, scale-free finish ready for site coating or direct installation. Full magnetic particle inspection is conducted on every piece to detect surface and near-surface flaws before release. Our QC team also verifies dimensional compliance with ASME B16.9 tolerances, wall thickness uniformity and material identification to guarantee each A234 WPB ASME B16.9 fitting meets project specification.

Haihao Group supports Pakistani EPC contractors and end users with full documentation packages, including material test certificates and inspection reports, to streamline project acceptance. We can also accommodate custom surface coatings, additional non-destructive testing and dedicated packaging for long-distance transport.
