Q:The pipe connections have different diameters. Reducing the diameter, what else?,
Six links, or even moreAccording to material classification, same material, different material
Q:PT1/4 large diameter pipe joint? No figure urgently
The thread has a taper of 1:16, equivalent to 55 degrees taper pipe thread, or ZG
Q:Hydraulic jointWho knows the hydraulic connection "3/8*25.4=9.525" refers to the connection?
A part of a hydraulic system between a high pressure tubing and a high pressure tubing.Classification: hydraulic hose, high pressure ball valves, quick couplings, odd intention ferrule type pipe joint, welded pipe joints, high-pressure hose, transition pipe joint, sleeve type pipe joint, three way pipe joint, non-standard pipe joint, flaredfitting, rectangular pipe joint, rotary tube connector, quick connector, stainless steel pipe fittings, copper fittings.
Q:What is the difference between the PVC joint and the PVC pipe joint?
What are the specifications of PVC threading tubes?:A metal tube 1, ordinary carbon steel wire (wire casing pipe) 2, metal flexible pipe (galvanized pipe, stainless steel pipe, plastic coated metal snakeskin snakeskin tube)
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:Will that be all right? Then there's the PPR pipe joint on the right. Is that ok?
If you don't feel comfortable, you can ask the master to change it for a whole 2 meter tube.
Q:About thread, pipe joint standard question
Or do you have to turn over every now and then?. Thread knowledge, personal feeling is quite complicated.
Q:Hydraulic pipe quick coupling principle of hydraulic pipe joint
JB/T6381 ~ 6385-1992 burking hose connector has the advantages of convenient installation, but added a tightening process. After the hose is damaged, the joint coat can not be reused, and it is made up of a steel wire braided hose. The utility model can be connected with a welding pipe joint sealed with a O ring. Pipeline system suitable for oil, water and gas as medium. Medium temperature: Oil: -30 ~ 80 degrees Celsius; air, -30 ~ 50 degrees Celsius; water, 80 degrees below JB/ZQ4427 ~ 4428-1986, three valve type hose joint assembly, do not need to remove the rubber tube of the outer layer. A slightly different diameter of hose hose, hose on the joint coat of pre compression to compensate. Hose pre compression in 31% ~ 50% range to ensure no leakage under the pressure of work, will not pull glue, cover does not break. With the welded pipe joint, quick joint, sleeve type pipe joint used for oil, water and gas pipeline system for medium, working pressure, medium temperature by connecting hose limited JB/ZQ4429 ~ 4431-1986 quick change connector (both open and closed) tube apart and self sealing pipe. In the liquid will not be lost, so it is suitable for frequent disassembly occasions. The structure is complex, and the local resistance loss is greater. Suitable for oil and gas pipeline system for medium, the working pressure is lower than 31.5MPa, the medium temperature of -20 to 80 DEG JB/ZQ4434-1986 quick change connector (both ends open) for oil and gas pipeline system for medium, the working pressure of medium temperature according to connecting hose limited JB/ZQ4435-1986
Q:Drawing design, drain cross dry pipe is flexible cast iron pipe, vertical pipe is PVC pipe joint
But in actual construction, because the special AD type bottom joint is more expensive, the construction unit usually adopts the cast iron pipe elbow to deal with the problem of reducing the diameter of the two kinds of materials.
Q:Hot melt pipe joint leakage how to do?
3, with polyurethane waterproof powder (generally used in toilet waterproof), after water transfer brush in the water leakage.4, with weather glue hit in the water leakage.
Our main products ranges from 50 series solid lubricating bearings, 10 series self lubricating bearings, 20 series boundary lubricating bearings, 30 series bimetal bushings, 90 series wrapped bronze bushings, 70 series decentralized solid lubricating bearings and FD filled PTFE bushings. The raw materials include high-load brass, tin bronze and aluminum bronze.
