Product Description

A105 Forged Steel Flanges Manufacturer | Global Bulk Supplier

At Xi’an QinSteel Trading Co., Ltd, we engineer A105 Forged Steel Flanges that set the benchmark for durability and precision in high-pressure industrial systems. Trusted by oil & gas giants, power plants, and engineering contractors worldwide, our flanges combine ASTM A105 carbon steel’s robustness with closed-die forging excellence. Whether you need standard ASME B16.5 weld neck flanges or custom-designed solutions, we deliver bulk orders with unmatched speed and compliance.

Product Description

The products are the backbone of critical piping networks, designed to withstand extreme pressures (up to 2500lb) and temperatures. Available in weld neck, slip-on, blind, threaded, and specialty types like orifice flanges, our products meet ASME B16.5, API 6A, EN 1092-1, and JIS B2220 standards. From DN15 to DN3600 sizes, we ensure leak-proof performance for offshore platforms, refineries, and valve assemblies.

Why Our A105 Forged Steel Flanges Stand Out？

Premium Material & Craftsmanship

ASTM A105 Carbon Steel: Optimized for tensile strength and corrosion resistance.
Closed-Die Forging: Enhances grain structure for uniform stress distribution.
Surface Treatments: Anti-rust coatings or galvanizing available for harsh environments.

Global Compliance, Local Reliability

Our flanges are certified to API, ASME, EN, and JIS standards, with NACE MR0175 and PED compliance upon request. With regional warehouses in the Middle East, North America, and Asia-Pacific, we slash lead times by 40% for urgent projects.

Customization Without Compromise

Need non-standard A105 Forged Steel Flanges dimensions, RTJ facings, or sour service grades? Our R&D team provides CAD-supported OEM solutions, backed by sample testing to ensure fit and function.

Applications

Oil & gas pipelines (onshore/offshore)
Power plant turbine connections
Petrochemical refinery equipment
Water treatment systems (AWWA C207 compliant)
