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:New standard, how can the pipe joint be labeled, such as "3/4" taper pipe thread?
Pipe fittings 3/4 refers to the pipe fittings of six points (6 British points), DN (diameter) of 20mm, the outer diameter of 26.8mm.Supplement:1 inches =25.4 mm, =8 British points, 1/2 is four points (4 British points), DN diameter 15mm, 3/4 is six points (6 points), DN20mm.
Q:PVC can the pipe joint be butted with the joint? How do I get it?
For example: 110mm diameter PVC pipe joint two, to connect them, you can cut a 110PVC tube (length 8cm), at the end of a first pipe with special glue inserted into a connector, then put another head on glue, then inserted into another joint, so ok.
Q:What do you mean by pipe joint 3/4-150?
3 / 4 is a conical English thread, which should be 24.5*14. -150 doesn't know what it means
Q:What are the types of hydraulic couplings?
The main domestic A, B, C and H, A type is most common,
Q:What is the difference between the pipe and the pipe joint?
Two, plastic pipe type 1, PVC (PVC-U) plastic wire pipe (hard tube), 2 and PE threading pipe (winding hose) 3, plastic bellows (flame retardant bellows, wire harness casing, high density bellows, high temperature protective casing, etc.)
Q:Can the pressure vessel pipe joint adopt G thread? Why?
Can not. G threads are not sealed enough.The following three threads can be used.1.55 degrees taper external thread R and cylindrical external thread Rp matching2.55 degrees taper external thread R and taper external thread Rc fit3.60 degrees taper internal and external thread fit PT.Glass can not be sealed only by thread.
Q:What is a slot type mechanical joint?Copy search
The utility model relates to a groove connecting pipe which has the function of sealing and sealing, and mainly comprises three parts: a sealing rubber ring, a clamping band and a locking bolt. The inner rubber sealing ring is arranged on the outer side of the connecting pipe and is matched with the pre rolling groove, and then the outer ring is buckled on the rubber ring, and then can be fastened with two bolts.
Q:PPR pipe joint leakage, do not want to change pipes, what is the good way?
You did not explain is not with threads, if you want to screw thread, cut threaded joint is broken, then a good joint,
Q:PPR pipe joints did not plug in the melt, in the end will leak?
A, in general, as long as the PPR hot melt pipe effective connection, through the fusion will fuse together, will not leak, and if not assured, it is recommended to re melt.Two, the pipeline before welding to seriously clean pipes and appearance, cleaning pipe appearance of oil, impurities and burrs. To carefully insert pipe length should be appropriate, should be symmetrical flange to discuss the formation of pipeline connection, if not well proportioned, stability that side, reflected weld is not ideal, the discussion is not difficult to guarantee Water Leakage, you should promptly reconnect.
