In the former piece, we learned how to choose a proper clamp joint. In fact, besides the design and installation, the position is also matter. If the clamp is too tight, it will extrude the hose. While this will cause hose distort. Thus you’d better not set the clamp too close to the hose end. Because there was leak or fall risk when set it at pressure. OrientFlex suggests the distance between clamp and hose end is at least 4mm.
In another hand, you may worry about if the material is corrosion resistant. Thus the work condition becomes the most important factor.
Is your clamp work at high temp?
Nylon is a great material for clamp joint. Because it can bear 125℃ and shortly for 150℃. However, in the most cases, the work condition is much higher. Thus we suggest you choose the metal one.
Worry about the weather?
For most of the plastic clamps, exposure to the UV is the main reason for aging. Black clamp can effectively resist UV and the service life is over 10 years. But if you want more longer service life, the metal clamp is the first to choose. Because it can directly work under UV for over 10 years. Zinc coated steel clamp (W1-W2) is more suitable for dry climate. But if refers to wet, you should choose stainless steel (W3-W5).
Clamp joint use with chemical
Many clamps are used in corrosive environment, especially in wet condition. Thus a plastic or W4/W5 steel clamp is better. For a long service life (over 25 years), you have choose the high grade material. While the Ni-Cr alloy is the best choice.
Clamp joint use for sterilization
For medical condition, you have to sterilize the clamp before use. But it’s really a hard process for it. Only several material can bear it. Among them, stainless steel is the best one. Because it can bear most of the disinfectant such as ethyl and alcohol.
Above are the factors to choose a proper clamp. In fact, choose a reliable supplier is also matter. OrientFlex works on hoses and relevant joints over 16 years. We have exported to over 130 countries and received good reputation. Contact us now and get more details.
