Metal hose clamp

1 Introduction metal hose clamp is an important part of modern industry. Metal hoses for wire, cable, wire and cable protection tube and civil shower hose Automation Instrumentation signals specifications from 3mm to 150mm. Small caliber metal hose (inner diameter 3mm-25mm metal hose clamp) is mainly used for precision optical ruler of the sensing circuit protection, industrial sensor line protection. 2 advantages of metal cable protection metal cable protection tube 1, flexible metal hose between pitches. 2, metal hose has good scalability, non-blocking and stiffness. 3, light weight metal hose, caliber consistency. 4, metal hose flexibility, repetitive bending resistance, good flexibility. 5, metal hose corrosion resistance, high temperature resistance. 6, metal hose rodent, good abrasion resistance, to prevent the internal wiring being worn. 7, metal hose bending resistance, tensile properties, resistance to lateral pressure and strong. 8, metal hose soft, smooth, easy threading installation positioning. Factors affect the quality of the installation (1) clamp may not have pores, trachoma, shrinkage cracks and other defects. Materials and Performance (2) seals must comply with the requirements, the sealing surface may not have bubbles, inclusions, cracks, uneven and other defects, can not use the aging of the rubber ring. (3) the snap ring in the moving distance within the clamp fitting stretch theoretically half the amount, to the amount of actual real, if it is not, then the amount of stretching can not meet the requirements of the pipeline. In order to promote permit sealing effect, supporting the factory and left and right end tube clamp, the actual project should not use ordinary pipe directly instead of end of the tube, and the flatness of the end of the tube end and the axis of verticality and the end itself has certain requirements, size is not standard makes the telescopic joint is greatly reduced, can not meet the requirements. Size (4) end of the tube diameter to choose positive bias, or clamp ring pressing force is not enough to affect the joint seal. Note 4 Installation (1) to control the snap ring from the end of the tube distance L. L to combine manual control, when the gap between the two pipe ends of the hour, to ensure the snap ring just stick to the slope. (2) In the case of a snap ring position determination, to determine the size of the gap between the two pipe ends of the pipeline by calculating the elongation according to the ambient temperature during the construction. Construction should ensure deviation size. (3) Under certain preconditions moving distance, the snap ring and end of the tube weld seam height, width and squareness errors snap ring plane and end of the tube axis, the smaller the amount of stretching the joint, the worse the effect. Impurities on welding spatter (4) end of the tube and the snap ring end tube was sealed before installation to remove welding slag sealing surface to ensure sealing effect.
