3, does not require special installation work, easy installation and removal; 4, the locking function is not affected lubrication; 5, the temperature change does not make connections loose; 6, with durability; flange usage instructions: When using the pipeline liquids, gases, mostly coupled flange connection. In order to reduce the (anti-corrosion, high-altitude, underground passage, etc.) special conditions replacement frequency, use a good anti-corrosion stainless steel flanges or PVC plastic and other materials Zhangqiu stainless steel screws, then we should use stainless steel fasteners (screws, nuts) to join and fixed. The main characteristics of the flange connection: 1.1 screws, nuts firmly locked in the pre-process time can cause cause uneven flange faces are not parallel (Figure 1). Namely: flange with screw locking direction is not perpendicular to the surface lead screw and nut threads role is not in full contact. 1.2 In order to ensure a good seal, will increase the rubber gasket between the two stainless steel screws Qufu flange, when the locking torque force reaches safe safety, but when there is still a gap between the stainless steel screw flanges and rubber gaskets, the operator often Liangshan will continue to force the locking stainless steel screws, causing the locking force exceeds safe torque. 1.3 During installation, there is often a hole is not on the top and bottom flanges or some eccentric (screw mounting holes can not be passed), forced threaded mounting screws can cause the appearance of injuries, plastics, iron and other debris can fall into the screw and screw cap screw them.
