Metal hose is a high quality flexible material in modern industrial pipeline. Besides, it has wide usages. Generally, it consists of corrugated hose, metal net and joint. The inner tube is spiral stainless hose. While the net is stainless steel braid. Metal hose fitting is also matter in the practice. In fact, joint determines if the hose can work normally. However, each joint has its own features. Then How to choose a proper joint? Let me give you some tips.
First, choose metal hose fitting based on the hose
That’s to say, the size and shape of joint should match the hose.
Second, choose metal hose fitting based on the medium
Metal hose can deliver types of mediums such as water, gas and oil. While these mediums have their own features. Thus you have to use different joints for these mediums. If it’s air, I suggest you chose carbon steel joint. But if it’s water, brass or stainless steel joint is much more better.
Besides, you should concern the temp and pressure. Because if them beyond the joint bear range, it may cause security accident. To avoid corrosion from mineral oil, most of the joints absorb electroplate treatment. While if there was sealing on the joint, you should make sure the material fit the medium.
Third, focus on the work condition of metal hose fitting
Before purchase joint, you should check the work condition first. While the check should include wet, dust, corrosion and other situations. Then choose the right type and material. For example, if the hose exposed in corrosive such as acid gas, you must use stainless steel joint.
Last, pay attention to the valve structure
Generally, valve structures have 2 way switch, single way switch and double open types. Thus you have to confirm which the type is. Because there will be fluid flow out when separate. Then it requires special joint for such valve.
