JR Netal Flexible Hoses

Overview

Metal hoses are an indispensable part of modern technology with its high demands on piping systems for a wide variety of media and temperatures. High flexibility and highest pressure and temperature resistance characterize our product program and allow their use in many areas,notably in heating, plumbing and air conditioning systems, in the oil and gas industry, in the chemical and food industry, in machine and equipment construction, ship building, railway and automotive engineering.
The Stainless steel corrugated hose is especially designed to achieve several objectives in pipe work design. These include, absorption or vibration, operate under vacuum, handle temperature extremes, suppress rigid pipe noise transmitted, accommodate reciprocating and flexing movement, operate effectively under high pressures and adjust or correct for misalignment. Stainless steel corrugated hose is a general purpose industrial hose and is available in different grades of stainless steel including 304, 316 & 321.
This type of hose is also known as pump hose connectors. These hoses are sized to a specific length for attaching to pumps. Its flexible braided construction absorbs vibration to reduce wear and tear on equipment. To connect the pump connector hoses you need to bolt two same-size flanges together. You will also need a gasket to complete the seal.
To save money and time, design and engineering offices increasingly use flexible metal hoses instead of rigid connection elements. Boilers, chillers, dishwashers and washing machines can be easily installed without soldering and welding works. In addition, they compensate for inaccuracies in installation, compensate for thermal expansion caused by temperature fluctuations and avoid vibration and noise transmission. The material being stainless steel, they easily meet the requirements for corrosion resistance, diffusion and aging resistance.
For most practical applications, the fatigue life of metal hose assemblies is not an issue. The flexible connection usually achieves easily the life span of the entire plant. Where there are exceptional stresses such as major movements, pressure fluctuations etc., those must be (mathematically) taken into account. If the problem can be captured fairly precisely, in most cases a reasonable design is possible. Nevertheless, despite ever-improving tools, especially in the field of calculation, it is often not possible to predict exactly the service life or the behavior of a hose. In these cases, it is inevitable to perform (as practical as possible) tests.
