Q:How to use the clamp type pipe joint?
The sleeve joint is usually used in the middle of the gas or liquid delivery pipe, so it is convenient and quick to use
Q:PPR pipe joints did not plug in the melt, in the end will leak?
1, pipe and pipe fittings should be adopted hot melt essentials, not allowed in the pipe and pipe fittings directly to the wire, and metal pipe can flange connection, and with water device connection, must use metal insert pipe fittings;2, the construction of hot melt connection must use the quality of reliable hot-melt equipment to ensure the quality of welding;3, the use of special scissors cutting vertical pipe shall be smooth without burr, argot;4, clean welding pipe fittings, the quality of sand, dust and other restraint damage are discussed; and the heating head is welding material inherited size related firmly in the hot melt machine, connected to the power supply, heating temperature to reach the best looking head;
Q:Man, can you send me some national standards? Mainly for hydraulic use
Here you are, some European companies, but you need to download them on the Baidu Library
Q:Stainless steel pipe, wire joint leakage how to make up?
1) want to save trouble, buy special glue to block, general hardware store can buy;2) the silk joint opens, the more winding some raw rubber tape, then turns tight to see whether can solve the problem;3) if it is a silk joint, replace the wire joint;4) the pipe is re tapped or replaced with a new pipe;
Q:How much is the monofilament of the 304 pipe joint?
If it is conventional, the basic can be connected, Sheng Jiang Industrial products have such joints, called water pipe joints
Q:What's the difference between pipe repair device and clamp type flexible pipe joint?
Generally applicable range is less than 16 kilograms, can not solve the limit problem, limited position can not solve the problem of flexible axial compensation.
Q:What are the installation requirements of the card sleeve joint?
The ends of the pipe shall be flush. The pipe should be flush in sawing grinding wheel and other tools, and burr cleaning and high pressure air blowing after use.When installing, the coaxiality of pipe and joint body should be kept as far as possible. If the pipe deflection is too large, it will cause sealing failure.The pre assembly force should not be too large. The inner blade of the clamping sleeve is just inserted into the outer wall of the pipe, and the clamping sleeve should not be deformed obviously. When the pipeline connection, and then according to the specified tightening force assembly. The tightening force of the phi 6-10mm card sleeve is 64-115N, Phi 16mmr 259N, Phi 18mm is 450N. If the sleeve is badly deformed at pre assembly, it will lose its sealing effect.(2) prohibit adding sealant and other fillers. In order to obtain better sealing effect, the sealant is coated with sealant, and the sealant is poured into the hydraulic system, causing the hydraulic components, such as damping holes, blocked and so on.(3) when connecting the pipe, the pipe should have enough deformation allowance to avoid the tensile stress of the pipe.(4) when connecting the pipeline, it should be avoided to be subjected to lateral force; the lateral force will cause the seal to be too lax.
Q:How to choose the connection mode of clamp type flexible pipe joint correctly
Steel ring clamp type flexible pipe joint with pipe end / short tube clamp type flexible pipe joint.Comparison of advantages and disadvantages between pipe end connection and steel ring connection:Butt welding of pipe ends adopts low welding technology
Q:Pipe joint thread, said in 2 / 3 / 4 points, what does that mean, how to convert ah?,
This appellation is the traditional British appellation, which is also used in the machinery industry for addressing the diameter of bolts4 in charge of diameter is 15mm (Dn15)6 points 20mm (Dn20)The pipe diameter is not 2 points, 3 pointsThe 25mm diameter pipe is called 1 inch tubeDn32mm inch tubeDn50mm 2 inch tubeDn75mm 3 inch tubeDn100 4 inches
Q:What does national standard joint jb/t6381.2-92 mean?
JB/T, 6381.2-92, cone welded, straight through tubular, threaded, pipe couplings, machinery, industry standards, have been repealed,
