Q:Joint type of pipe joint
Straight through joint, straight joint, three way joint, elbow, live nut joint, hinge joint, plug head, transition joint, etc.Double card sleeve assembly: front clamping ring, back clamping ring, nutMaterials are commonly made of stainless steel and carbon steelMetric, inch thread and American Standard NPT, PT, G are pipe thread.NPT is the abbreviation of National (American) Pipe Thread, an American Standard 60 degree taper pipe thread, used in North America. National standards refer to GB/T12716-1991
Q:What is the manual pre assembly procedure for the EO-2 joint?
4, the pre assembly force should not be too ambassador, the inner edge of the card sleeve is just inserted into the outer wall of the pipe, and the clamping sleeve should not have obvious deformation. When the pipeline connection, and then according to the specified tightening force assembly. Phi 6-1 card sleeve tightening force is 64-1 15N, 16 MMR 259n, Phi Phi 18mm for 450n. If the sleeve is badly deformed at pre assembly, it will lose its sealing effect.Matters needing attention:1, prohibit adding sealant and other fillers. Some people in order to obtain better sealing effect, in the card cover with sealant, the result of sealant is poured into the hydraulic system, causing hydraulic components, such as plugging holes.2. When connecting the pipe, should make the pipe has enough deformation allowance, avoid the pipe by tensile force.3. When connecting the pipeline, it should be avoided to be subjected to lateral force, lateral force caused by the assembly seal is not strict.4, when connecting the pipeline, should be a one-time good, avoid repeated disassembly, otherwise it will make poor sealing performance.
Q:What does R1/2 pipe joint mean?
Large diameter (datum plane) =20.955Medium diameter =19.793Path =18.631Pitch =1.814The number of teeth contained in each inch is 14 teeth
Q:New standard, how can the pipe joint be labeled, such as "3/4" taper pipe thread?
60 degrees taper pipe thread: NPT3/4"55 "taper pipe threads: external thread -R3/4", internal thread -Rc3/4"
Q:What joints do nylon hard tubes work on?
(I) flared type pipe jointApplication: oil, water, gas and other non corrosive or corrosive medium pipe joint with steel pipe specifications and flexible pipe welding, has the characteristics of reliable connection, good sealing performance, so it is widely used in oil refining, chemical industry, light industry, textile, metallurgy, national defense, aviation, ship etc.; also suitable for hydraulic transmission of various mechanical engineering, machine tools and other equipment pipeline. Flared tube fittings are manufactured in the following six categories:
Q:Consult the problem of the pressure at the entrance and exit of the pipe joint
Assuming that your 3 oil outlet, load is infinite, as follows, three load (cylinder or motor) are not action, three outlet pressure is 2MPa, three outlet pressure gauge pressure is 2MPa
Q:PEX floor heating pipe fittings and fittings are aluminium plastic pipes?
Its advantages and disadvantages:(1) good mechanical performance;1., good pressure resistance, shock resistance, rupture resistance2., with a strong plastic deformation ability, can be greater than 5D radius within the arbitrary bending, without heating, not rebound; (D for pipe diameter)3. light weight, same flow diameter composite pipe weight is 1/3 of steel pipe, 1/12 of galvanized pipe;
Q:Can the sleeve type pipe joint be disassembled and assembled several times?
The setting times of the sleeve type pipe joint are regulated. Generally speaking, the disassembly and assembly will affect the use of the clamping sleeveSome domestic tubes, nuts, silver plating) support multiple disassembly, because silver plating increased the number of inlay

Q:What is the function of the pipe joint?
This is a general term for connections that can be disassembled in a fluid path. It mainly includes welding type, clamping sleeve type and flaring type
