New 8" male thread conical couplings in 316 stainless steel for OROFLEX WELL hose: maximum tensile strength with less material, less weight and much lower cost.
On May 16, 2025, a tensile test was carried out at the LGAI Technological Center S.A. laboratory(Applus laboratories), on behalf of TIPSA-KURIYAMA GROUP, with the aim of validating the mechanical performance of the new 8" tapered couplings in 316 stainless steel, specially designed and optimized for integration with OROFLEX WELL hose.
This type of test is essential to verify the reliability of the "hose + coupling" assembly in industrial applications where safety and durability are a priority.
The hose was subjected to a three-stage tensile test:
1. progressive application of load up to 11.6 tons (113.8 kN).
2. Maintenance of this load for 15 seconds. 3.
3. Increasing load until complete rupture of the hose.
The assembly formed by the OROFLEX WELL 8" hose and the new 316 stainless steel male thread conical couplings showed excellent structural strength. The specimen withstood the established working load without deformation, and continued to resist until it reached a maximum breaking load of 24.78 tons, more than double the reference load.
The breakage occurred at the junction area between the hose and coupling, confirming that both the hose body and the new coupling design maintained their integrity under extreme stress conditions.
The combination of OROFLEX WELL hose with the new 8″ tapered male threaded fittings in 316 stainless steel offers a mechanically robust, lightweight and efficient solution for demanding environments. These results consolidate the development as a highly reliable alternative for operations where traction, pressure and resistance to external agents are critical factors.
