Ultra-high pressure pipe fittings
1500BAR High-Pressure / High-Strength Materials / Special Heat Treatment / Self-Tightening Seal / Precision Forging / 100% Inspection / Quick Coupling / Long-Life Design
Product Overview
Ultra-high-pressure fittings are specialized fluid connection components engineered for 1500BAR high-pressure conditions, forged from high-strength alloy steel. The product line includes ultra-high-pressure rigid hoses, hose assemblies, fittings, and valve blocks, widely used in industrial applications such as water jet cleaning, high-pressure testing, and chemical high-pressure reactions. Through advanced heat treatment processes and precision machining, we ensure safety and sealing reliability under 1500BAR operating pressure.
Key Features
Rated working pressure: 1500BAR; burst pressure ≥ 4x; industry-leading safety factor
Constructed from 42CrMo/316Ti high-strength alloy steel, with a yield strength ≥ 900 MPa.
Quenched and tempered + surface nitriding; hardness HRC26-30; excellent fatigue resistance
Tapered self-tightening seal design: higher pressure ensures greater reliability and zero-leakage guarantee.
Forging + CNC machining, refined grain structure, pressure resistance increased by 30%
Perform hydrostatic pressure testing on each unit individually and provide material reports and inspection reports.
Quick-change coupler design; mold change time ≤ 30 seconds to boost efficiency.
Fatigue life ≥ 80 thousand cycles; long maintenance interval; low operating cost
