As an established China high pressure fittings manufacturer, we specialize in the engineering and production of heavy-duty high pressure stainless steel fittings and forged high pressure pipe fittings. Built to deliver complete containment and zero-leakage safety in the most punitive operating environments, our heavy-series adapters handle pressure spikes, thermal shocks, and mechanical vibrations. Every component is structurally optimized to exceed the continuous working pressure ratings required by modern subsea, industrial, and heavy machinery fluid networks.
Heavy-Wall Forged Engineering for Ultimate Fatigue Resistance
Unlike standard hydraulic adapters, our 10000 psi stainless steel hydraulic fittings are engineered with a significantly expanded cross-sectional wall thickness.
Premium Forging Blanks: All structural bodies (such as elbows, tees, and crosses) are precision-machined from grain-aligned forgings to eliminate internal porosity and prevent micro-fracturing under cyclic loads.
Solid Hex Barstock: Straight connectors and nipples are produced exclusively from high-density, cold-drawn solid hex barstock, providing superior thread tensile strength.
Deep-Thread Engagement: Female and male thread profiles are machined to extended lengths to ensure absolute mechanical engagement, preventing thread stripping or blowout during intense water-hammer events.
Technical Specifications & Sourcing Grid
Material Composition: Forged and barstock variants available in AISI 316L (1.4404), AISI 316Ti (1.4571), and AISI 304 (1.4301). Super Duplex variants are available for high-salinity offshore systems.
Pressure Classification: Nominal operating pressures range from 3,000 psi (210 bar), 6,000 psi (420 bar), up to ultra-high thresholds of 10,000 psi (689 bar) with a documented 4:1 safety burst factor.
Thread Port Formats: Heavy NPT (National Pipe Thread), high-pressure BSPP (G thread) with Type E/F soft seals or metal-to-metal cone interfaces, and heavy-duty metric threads.
Comprehensive Configurations: Forged 90° Elbows, 45° Elbows, Forged Tees, Forged Crosses, High-Pressure Hex Nipples, Reducing Adapters, and Gauge Couplings.
Heavy-Duty Structural Series Overview
Threaded High-Pressure Class: Forged fittings manufactured in accordance with ASME B16.11 and SAE J514 standards, specifically adapted for heavy industrial fluid transfer.
Heavy DIN 2353 / ISO 8434-1 (S Series): High-pressure metric compression connectors engineered to seal thick-walled seamless tubes up to 630 bar.
SAE 6000 psi Code 62 Flanges: Integral and split flange connections engineered to bridge heavy-duty flexible hoses directly to solid high-pressure pump blocks.
