Haihao Group Supplies Large Batch of Seamless Carbon Steel Tees to Pakistan Project

Haihao Group has successfully completed another overseas shipment – a large batch of seamless carbon steel tees supplied to a key pipeline project in Pakistan. The order includes a full range of equal tees and reducing tees, manufactured in accordance with ANSI/ASME B16.9 standards to ensure reliable performance in high-pressure and low-temperature pipeline systems.

This shipment covers various sizes from 2″ to 20″, including both standard (STD) and extra strong (XS/SCH120) wall thicknesses. The tees were produced using high-quality ASTM A234 WPB and ASTM A420 WPL6 materials, offering excellent strength, impact toughness, and weldability for demanding industrial applications.

All fittings underwent sandblasting and magnetic particle inspection (MPI) to guarantee surface quality and detect any potential defects. In addition, each product was coated with black paint for enhanced corrosion protection during storage and transportation.

Key products in this shipment include:

• Equal Tees (2″–20″), seamless and butt-weld ends, manufactured to ASTM A234 WPB / ASTM A420 WPL6.
• Reducing Tees (18″×12″, 14″×12″, 10″×6″, 6″×3″, etc.), suitable for different pipeline connections.
• Special high-pressure tees with SCH120 wall thickness, ensuring durability under elevated pressure and temperature conditions.

The ASTM A234 WPB carbon steel tees are ideal for medium and high-temperature service, while the ASTM A420 WPL6 low-temperature tees are specifically used in cryogenic and low-temperature pipelines, such as natural gas and LNG systems.
