Haihao Group Delivers ASTM A182 F321 and F316 Forged Fittings for a UAE Industrial Project

As part of its ongoing commitment to supporting global energy and industrial projects, Haihao Group has successfully completed the production and delivery of a full range of ASTM A182 F321 and F316 stainless steel forged fittings for a client in the United Arab Emirates (UAE).

These fittings are engineered to meet the rigorous performance standards required in modern piping systems, ensuring exceptional mechanical strength, corrosion resistance, and pressure reliability under demanding service conditions.

Comprehensive Supply Scope

The order covers multiple types and sizes of ASME B16.11 forged fittings, including both socket weld and threaded connections, designed for high-pressure applications up to 3000#.
The supplied components include:

• Socket Weld Equal Tee – 3/4″, ASTM A182 Gr. F321, pressure rating 3000#, suitable for compact, high-strength piping systems.
• Threaded Equal Tee – 1/2″, ASTM A182 Gr. F321, 3000#, precision machined to ensure leak-free joints.
• Double Threaded Nipple (NPT) – 3/4″ × 75mm (3″), ASTM A312 TP316L stainless steel, SCH80S wall thickness, ideal for corrosion-prone or high-pressure environments.
• Threaded Equal Tee – 3/4″, ASTM A182 Gr. F321, 3000#, offering stable flow and reliable connection.
• Threaded Branch Outlet (Threadolet) – 6–10″ (150–250 mm) × 1″ (25 mm), ASTM A182 F321 SS, 3000#, designed for reinforced branch connections.
• Threaded Equal Tee – 1″, ASTM A182 Gr. F321, 3000#, used for medium-to-high pressure systems.
• Socket Weld Branch Outlet – 2″ × 3/4″, ASTM A182 Gr. F316, SCH80S (3.91×5.54 mm), 3000#, providing superior corrosion resistance and structural integrity.

Each fitting is manufactured to precise tolerances, with strict control over machining, threading, and surface finish to ensure perfect compatibility with customer piping systems.

Quality Assurance and Documentation

To maintain full transparency and traceability, Haihao Group supplied the client with a complete set of technical and quality documents, including:

• EN 10204 3.1 Mill Test Certificate (MTC)
• Dimensional inspection report
• Impact and mechanical test reports
• Chemical composition report
• Nondestructive testing (NDT) report

All fittings were inspected and verified before shipment to guarantee conformity with ASME B16.11 and ASTM standards. This meticulous attention to quality ensures the fittings perform reliably even in high-temperature, high-pressure, or corrosive service environments.
