Product Description:

Steel Pipe Fittings Butt-Welding End Caps

Features standards and products of our Butt-Welding End Caps:

Features of Butt-Welding End Caps:

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.

Standards of Butt-Welding End Caps:

Our welding fittings are manufactured in compliance with the following appliance standards:

ASME B16.9   ASTM A234   MSS-SP43   WPHY60   JIS B2311   DIN2605

                      ASTM A403   MSS-SP75   WPHY65   JIS B2312   DIN2606

                      ASTM A420   WPHY42    WPHY70   JIS B2313   DIN2616

                      ASTM A860   WPHY52                                       DIN2615

Q:How do you explain the pipe joint?
The fittings are expressed in part according to the British system
Q:May I ask what material EN39 is? Used to make a threaded pipe joint
It specifies the material and tolerance requirements of the steel pipe. From the material point of view, the steel in the EN39 standard is similar to that of China's Q235B.
Q:Hydraulic pipe joint seal, with raw meal belt and sealant that good?
Use sealant.It is not recommended to use the raw meal belt and can not be sealed. It will cause oil leakage. The raw meal belt will be contaminated by the oil, which is particularly easy to cause the phenomenon of the valve or plug the oil control port. If you must use the raw meal belt, then you must pay attention to the coil when you can not bring the raw material out of the joint, so as not to be sucked into the tank by oil.
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.
Q:How many bonding methods are there in the belt joint?
3. heat curing joint, the heat vulcanizing joint conveyor belt interface is completely closed, not susceptible to water wetting. Technology of belt vulcanizing joint is generally placed on the belt vulcanizer frame under the frame, both ends of the alignment, then put on the pressure plate, small thermal insulation board, insulation sheets, two vulcanizer installed on each side of 1-2 meters of the platform and fixed platform, the upper surface to the lower heating plate and flat surface homogeneous or slightly lower, also cannot affect the tension rod, the belt joint two on the platform began to cure. This method is a kind of joint is the best method that can guarantee the high coupling efficiency, but also very stable, joint life is long, easy to master, but the heat curing joint process is relatively complex, high requirements for personnel, cold bonding process is simple and short-term training posts.
Q:Apart from the air-conditioning, the high-pressure pipe is not tight enough. What shall I do?
Will affect the cooling effect, it is recommended to cut off the connector, and then use reaming device to expand after re installation. Charges will not be too high, dozens of blocks enough to be careful to be pit.
Q:Can flared and jacketed hydraulic couplings be used as gas line couplings?
Yes, but it's not economical.Hydraulic pipe joint pressure is very high, commonly used in 16MPa, 25MPa, 35MPa several levels.
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
Q:Who knows what the clamp joint standard is?
But why are the actual products very much the same? Because the company is different and not all over the world. Where will it be?
Q:Hydraulic jointWho knows the hydraulic connection "3/8*25.4=9.525" refers to the connection?
The most important part of the pre assembly of sleeve type pipe joints directly affects the reliability of the seal. A dedicated preprocessor is usually required. The small diameter can be pre joint in a vise. The concrete method is to use a joint as the mother's body and press the nut and the sleeve onto the tube. The utility model mainly comprises a sleeve type through pipe joint, a clamping sleeve type end through connection head, a clamping sleeve type three way pipe joint and other patterns. 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.
