Q:What joints do nylon hard tubes work on?
The pipe joint is the connecting tool between the pipe and the pipe, and it is the connection point between the component and the pipe.There are three kinds of hard tube joints: flaring, clamping and welding
Q:What are the types of hydraulic couplings?
Mechanical design manual fourth volumes, hydraulic pipe joints are there?. You go check it out,.
Q:Re series 24 degrees cone O ring seal pipe joint joint, corresponding to the national standard number is?
Heavy series 24 degree cone O ring seal pipe joint, corresponding to the national standard number is JBT 6382.4-1992 or JBT 6381.4-1992.Pipe joint: Hydraulic term. It is a part of a hydraulic system that connects pipes or sets a pipe on a hydraulic element. This is a generic term for connections that can be assembled and disassembled in a fluid path. It mainly includes welding type, clamping sleeve type and flaring type
Q:What's the difference between pipe repair device and clamp type flexible pipe joint?
Two kinds of pipe fittings can not be said which is easy to use, in the right place to use.Stainless steel pipeline repair device, plate repair device mainly made of stainless steel 201, applicable to low-pressure pipelines,
Q:Air conditioning outdoor units, pipe joints, frosting, or even icing
Find the right size of the six angle wrench, facing the cut-off valve, counterclockwise turn on the valve, clockwise turn off the valve.
Q:What's the meaning of the pipe joint 14-M18*1.5? What's the thickness of the wall?
I found that even if the same manufacturer of a batch of goods, the cone of these joints on the depth of the hole is often different, resulting in a leak, and this problem is often neglected. The correct approach is to connect the end of the pipe with what kind of joint, and the corresponding connection ends are prefabricated with the same type of joint, so that the leakage problem can be avoided to the maximum extent. The ends of the pipe shall be flush. The pipe should be flush in sawing grinding wheel and other tools, and burr cleaning and blowing with high pressure air before 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. If the pre loading force is unfavorable, the inner edge of the ambassador card 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. Phi 6-1 card sleeve tightening force is 64-115n, 16 MMR 259n, Phi Phi 18mm for 450n. If the sleeve is badly deformed at pre assembly, it will lose its sealing effect.
Q:Hydraulic pipe quick coupling principle of hydraulic pipe joint
Quick change joint, one is with one-way valve, and the other is without one-way valve. The application with a one-way valve, a one-way valve end is connected with the gas source, when the check valve closes automatically when connected to a one-way valve open end of the thimble. Self locking is the use of steel balls embedded in the groove, while the "cone - cylinder" sleeve to lock the ball.Type, type, structure diagram, characteristic table and standard number of pipe joint, welded pipe joint is welded by pipe and pipe. The sealing surface of the O sealing ring is sealed between the joint body and the pipe. The utility model has the advantages of simple structure, easy fabrication, good tightness and low requirement for the dimension precision of the pipe. High welding quality, inconvenient assembly and disassembly. The working pressure can reach 31.5MPa and the working temperature is -25 to 80 degrees. It is suitable for the piping system with oil as the medium. Table 6~14The JB966 ~ 1003-1977 card sleeve pipe joint is jammed and clamped by the deformation of the clamping sleeve. The utility model has the advantages of advanced structure, good performance, light weight, small size and convenient operation, and is widely used in the hydraulic system. Working pressure up to 31.5MPa, requiring high dimensional accuracy of the pipe, cold drawn steel pipe is required. The card sleeve is also of high accuracy. Piping systems for oil, gas and general corrosive media 15~26
Q:What is the nominal diameter of the phi 1/2 in the pipe joint?
1/4, 1/2, 1/8 is the nominal diameter of inch inch, inch in inches1/2 inches, usually read as "four thiophene"".
Q:What are the differences between hydraulic couplings and fittings and elbows?
The elbow is the pipe that changes the direction of the pipe. According to the angle, there are 45 degrees and 90 degrees, 180 degrees, three most commonly used, in addition, according to the project needs, including 60 degrees and other non normal angle elbow. Elbow materials are cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, nonferrous metals and plastics. The way to connect with the pipe is: direct welding (the most commonly used way), flange connection, hot melt connection, electric melting connection, threaded connection and socket connection. According to the production process can be divided into: welding elbow, stamping elbow, push elbow, casting elbow, butt welding elbow. Other name: 90 degree elbow, right angle bend, love bend and so on.
Q:For picture: hydraulic pipe joint M30*2H-G3/4
Order number ten 1CG-30-22One side is the M thread, and the other is the pipe threadIt's no use looking at the picture. It's just an ordinary joint seat.
