Product Description:

Features standards and products of our butt welding fittings:

Features of butt welding fittings:

1.       High class materials

Our products only use high class raw materials of carbon/alloy steel pipes made from NKK or MANNESSMANN equipment for ordinary, high pressure, low/high temperature,boiler and other purposes.

2.       Uniform wall thickness and perfectly round

This can be achieved by our particular technical knowhow and our quality control program.

3.       Accurate dimension

Efficient piping work can be made only with fittings of correct dimensions and shapes. Our fittings are finished to have accurate straight/ plane ends, beveled angle...etc. to applicable standards by means of two or three spindle beveling machines.

Q:How was the pipe joint named?
Use the end extension of the pipe for sealing without any other seals. The utility model has simple structure and is suitable for the connection of thin-wall pipe fittings, and is suitable for pipelines with low pressure of oil and gas as medium. The pressure is allowed to be used in table 41, table 27~41, GB5625.1 to 5653-1985Insert welded pipe jointThe length of the tube will need to be inserted into the pipe joints and pipe end until the connector end of the contact, the pipe and the pipe joint are welded together, can save over, but the pipe size is strictly applicable to oil and gas as the medium pipeline system table 43 ~ 49 JB3878-1985Cone seal welded pipe jointOne end of the connecting pipe is provided with an outer cone surface, and a O shape sealing ring is matched with the inner cone surface of the joint body, and is screwed with the screw thread. The working pressure is 16 ~ 31.5MPa, the temperature - 25 to 80 DEG C for oil as medium piping system table 50 ~ 62 JB/T6381 ~ 6385-1992Withhold hose connectorThe installation is convenient, but a tightening process is added. 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 to 50 degrees Celsius; water below 80 degrees JB/ZQ4427 ~ 4428-1986
Q:Air conditioning pipe joints how to remove, the joint is ring, there are similar to the spring on the oil seal
There is a special set of air conditioning pipes, disassembly tools, plastic. Generally sold air conditioning parts and steam insurance shops have sold, not expensive, that is, twenty or thirty yuan. Like a set of 4 or 6 forget?. Clip into the air conditioning pipe and pull it out. The principle is the use of this tool will spring open, air conditioning pipe on the ring on the spring.
Q:What are the links between hydraulic components and pipe couplings that are used to prevent leakage?
If it is a super high pressure seal (70 MPa or more), the metal cone can be used for hard sealing, that is, the inclined joint of the pipe joint is matched with the inclined plane at the component thread.
Q:What kind of tubing connections do you have?.
Pipe joint is detachable between the tubing and tubing, tubing and hydraulic components of the connection, it should satisfy the convenient assembly and disassembly, reliable connection, reliable sealing, small size, large capacity oil, small pressure loss, good processing etc.
Q:What are the types of tubing and pipe couplings?
According to connection tubing and pipe joints, pipe joints are welded, sleeve type, expanding type, press type form; each form of pipe joint,
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:The hydraulic pipe fittings how to distinguish the British, American, metric!
Metric thread tooth angle of 60 degrees, fine teeth; British American pipe thread pitch, basically the same, but the BSP screw tooth angle is 55 degrees, American pipe thread angle is 60 degrees. The difference between the metric and inch pipe screw thread, the:
Q:Hydraulic hose joint is spherical and cone sealing, threaded connection, what is the form of joint?
Hydraulic joints are often spherical joints, concave and convex.2 types of teeth with imperial teeth and unf.
Q:What are the standard drawing numbers for hydraulic couplings?
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 64-1 15N, 16 MMR 259n, Phi Phi 18mm for 450n. If the sleeve is badly deformed at pre assembly, it will lose its sealing effect.
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,
