Haihao Group Delivers ASME B16.11 A350 LF2 Forged Fittings to Russian Client

Haihao Group has successfully completed the production and shipment of ASME B16.11 A350 LF2 forged fittings for a key Russian client.

The order includes both galvanized and non-galvanized fittings, designed to perform reliably in low-temperature and high-pressure pipeline systems.

These forged components underwent heat treatment and hot-dip galvanizing, ensuring superior toughness, corrosion resistance, and extended service life under demanding operating conditions.

ASME B16.11 A350 LF2 forged fittings ready for shipment to Russia

Product Overview

The shipment consists of various types of forged fittings, including socket weld (SW) caps, threaded elbows, tees, and nipples, all manufactured according to ASME B16.11 and client-specific drawings.

Product List Summary:

• SW Cap 1″ CL3000 SW, Material: A350 Gr. LF2 CL.1
• SW Cap with Internal Thread 3/4″ NPT CL6000, Material: A350 Gr. LF2
• Threaded 90° Elbow DN25 CL3000, Material: A350 Gr. LF2 CL.1 + Hot-dip Galvanized
• SW Tee 1-1/2″ × 1″ CL3000 SW, Material: A350 Gr. LF2 + Galvanized
• Nipple 1/2″ S/3000 NPT, Material: A350 Gr. LF2 + Galvanized
• Coupling 1/2″ CL6000 / 3/4″ CL6000, Material: A350 Gr. LF2 CL.1 (per drawing)

All fittings are manufactured from ASTM A350 Grade LF2, a low-temperature carbon steel known for its excellent impact resistance and weldability.

The inclusion of hot-dip galvanizing adds a protective zinc coating that enhances corrosion resistance, making these fittings ideal for harsh climatic and industrial environments.

Manufacturing Standards and Quality Assurance

Every fitting was produced in full compliance with ASME B16.11 and client specifications.
Comprehensive heat treatment and non-destructive testing (NDT) were carried out to guarantee structural integrity and dimensional accuracy.

Each product was subjected to:

• Dimensional and visual inspection
• Hydrostatic pressure test
• Material test certificate (EN10204 3.1)
• Hot-dip galvanizing coating thickness inspection
• Heat treatment and hardness verification

The fittings were carefully packed for long-distance transportation to ensure they arrived in perfect condition for installation.
