Haihao Group Dispatches High-Pressure ASME B16.11 Forged Fittings and Low-Temp Caps to Russian Industrial Client
Haihao Group recently completed a pipe fitting shipment for a customer in Russia, covering 3000# forged fittings, a seamless cap and a range of stainless steel and low-temperature alloy steel grades. The order includes 304L, 316L, A350 LF2 Class 1 and A420 WPL6 materials, with products manufactured to ASME and MSS dimensional requirements.
The order combines socket weld fittings, branch outlets, a coupling and a seamless cap. Such a mixed fitting package requires careful control of material grade, pressure class, end connection and applicable standard for each item.
Product Details for the Russia Order
The core of this dispatch consists of high-pressure 3000# socket weld components designed according to international standards. Among these, our high-performance ASME B16.11 forged fittings were produced under strict quality management protocols to ensure zero-defect joint integrity during field installation.
Below is the detailed material and dimensional manifest for the delivered order:

| Socket Weld Tee | 1″ | CL3000 | A350 LF2 Class 1 | ASME B16.11 |
| Seamless Cap | 2″ | SCH XS | A420 WPL6 | ASME B16.9 |
| Coupling | 1″ | CL3000 | A182 F304/304L Dual Grade | ASME B16.11 |
Quality Assurance for Low-Temperature & Stainless Applications
When selecting ASME B16.11 forged fittings for high-pressure systems, structural integrity under high pressure and variable temperature ranges is paramount. The dual-certified ASTM A182 F304/304L and F316/316L forged items provide superior resistance to intergranular corrosion while retaining excellent mechanical strength during continuous operation.
For low-temperature process lines, Haihao Group supplied ASTM A350 LF2 Class 1 tees and ASTM A420 WPL6 seamless caps under ASME B16.9 standards. These low-temp materials underwent Charpy V-notch impact testing to ensure reliable performance without risk of brittle failure in low-temperature Russian environments.

Rigorous Testing and Export Packaging
Prior to shipment, all ASME B16.11 forged fittings and butt-weld caps underwent thorough quality control evaluations, including:
Dimensional & Visual Inspection: Strict compliance verification with ASME B16.11 and MSS-SP-97 tolerances.
Nondestructive Testing (NDT): Magnetic Particle Inspection (MPI) for carbon steel fittings and Liquid Penetrant Testing (LPT) for stainless steel components.
Surface Protection: Rust-preventive oil coatings for carbon/low-temp steel components and pickling/passivation treatment for stainless steel surfaces.
Export Packaging: Custom sea-worthy wooden cases with internal waterproof lining and heavy-duty strapping to prevent transit damage.
By delivering fully certified ASME B16.11 forged fittings with mill test reports (MTR) according to EN 10204 3.1, Haihao Group reinforces its position as a reliable partner for global energy and industrial infrastructure projects.
