Q:What are the standard drawing numbers for hydraulic couplings?
(two) 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.(three) when connecting the pipe, the pipe should have enough deformation allowance to avoid drawing the tube.(four) when connecting the pipeline, the lateral force should be avoided, and the lateral force will cause the seal to be too tight.(five) when connecting pipelines, should be a one-time good, avoid repeated disassembly, otherwise it will make poor sealing performance.
Q:Hydraulic pipe fittings, DIN, GB, American Standard how to distinguish?
ZG is a commonly known as cone, cone thread processing, pipe joint is generally the old GB marked Rc for metric threads to represent the thread pitch, with every inch of the thread number, this is the biggest difference between them, metric thread is 60 degrees equilateral tooth type. 55 inch thread is isosceles tooth type of thread, 60 degrees. Metric units for metric threads; British and American systems. Pipe thread is mainly used for pipe connection, the internal and external threads are closely matched with straight pipe and cone pipe two kinds. Nominal diameter refers to the diameter of the pipe to be connected. Obviously, the diameter of the thread is larger than the nominal diameter. 1/4, 1/2, 1/8 is the nominal diameter of inch inch, inch in inches.
Q:Re series 24 degrees cone O ring seal pipe joint joint, corresponding to the national standard number is?
There are many kinds of pipe joints, and the commonly used pipe joints can be divided into two kinds: hard pipe joint and hose joint. If in accordance with the connection pipe joints and pipe points, hard tube joint with flared type, sleeve type and welding type three, hose connector is mainly buckling type hose connector.In hydraulic system, the connection way of pipe and pipe joint is different. The screw is used to connect screw thread. The taper thread is screwed on its own vertebral body and is sealed with polytetrafluoroethylene and other substances. It is mainly used in the hydraulic system of medium and low pressure. The sealing effect of fine thread is very good, is often used in high pressure system, but it requires the use of combination washer or O ring to end closed, sometimes used copper gaskets, it is suitable for the pipe connecting pipe wall is thick, the main part of a joint body, and take over nut. When in use, the joint body is embedded in the target, and the end face is sealed by using the gasket mentioned in the front; the rubber seal is used between the joint body and the connecting pipe, and sometimes the spherical sealing method is adopted.
Q:Do you need adhesive for the sleeve joint of PVC wire pipe?
In my more than 10 years experience, in the piping, pipe joints such as glue, threading, threading device is easy to pass through the pipe joints, straight through and so on. Although the specification is to use glue, but the operation is very troublesome, I generally do not, no one to check you with no glue, just use the line tube inserted into the pipe joints or through the end can glue, threader easily through these joints. The line pipe is not easily disengaged and flooded when it is on the ground
Q:What are the sealing ways of pipe joints? Thank you
Pipe joint seal: thread seal, cone seal, end face seal.There are several kinds of thread seal:Hemp - thick lacquer, this is the most traditional.
Q:What does pipe joint "DD" mean?
Parts that work in a weak corrosive environment, such as covers, bearings, valves, hand wheels, etc., are joined mainly for connection, installation and maintenance.
Q:Hot melt pipe joint leakage how to do?
2, dry leakage parts, with Wang Yu (waterproof cement) to buy. Less water, very thick situation, large surface paste in the water leakage position. This method is also used to remedy cast iron pipes.
Q:Reinforced pipe joint,Used in chemical pipes
20# steel, JB 4726-2000 material "pressure vessel with carbon steel and low alloy" standard, SW socket welding.  40T025/01 is drawing number, SCH80 diameter specifications. See below;
Q:The pipe joint model is 1/2 "-14 teeth / inch"
. The 1/4, 1/2, and 1/8 marks in the thread refer to the diameter of the thread dimension, in inches. An inch equals 8, and a 1/4 inch is 2, so an analogy. The pitch of the English thread is indicated by the number of teeth per inch, such as 11 teeth per inch, and the pitch is =25.4/11=2.309mm.
Q:PEX floor heating pipe fittings and fittings are aluminium plastic pipes?
(four) excellent resistance to agingA. has good temperature resistance, high density PE working temperature -40~65 DEG C, cross linking PE working temperature -40~95 DEG C.B. anti-aging properties, cold brittle temperature is low, anti ultraviolet, anti-aging ability, in the absence of high heat and strong ultraviolet radiation conditions, 50 years of service life is recognized life time. After the aluminum plastic compound, enables in the withstanding pressure, the shock resistance ability to strengthen.(five) excellent health performance of aluminum-plastic composite pipe lining for the health level of the PE process without any lead such as heavy metal stabilizer, does not contain harmful ingredients and plasticizer, no mildew and microbial breeding, clean sanitation. The intermediate aluminum layer isolates oxygen and the gas permeability is 0.
