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.

Standards of butt welding fittings:

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

Q:What about the PVC-C joint?Catgut implantation. Where are the connections of the two tubes of the casing PVC-C?!
PVC pipe joint and butt joint, the best way is to add between the two joints of the same type of pipe, and then use special glue to connect.
Q:What are the installation requirements of the card sleeve joint?
The ends of the pipe shall be flush. The pipe should be flush in sawing grinding wheel and other tools, and burr cleaning and high pressure air blowing after 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.The pre assembly force should not be too large. The inner blade of the clamping 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. The tightening force of the phi 6-10mm card sleeve is 64-115N, Phi 16mmr 259N, Phi 18mm is 450N. If the sleeve is badly deformed at pre assembly, it will lose its sealing effect.(2) prohibit adding sealant and other fillers. In order to obtain better sealing effect, the sealant is coated with sealant, and the sealant is poured into the hydraulic system, causing the hydraulic components, such as damping holes, blocked and so on.(3) when connecting the pipe, the pipe should have enough deformation allowance to avoid the tensile stress of the pipe.(4) when connecting the pipeline, it should be avoided to be subjected to lateral force; the lateral force will cause the seal to be too lax.
Q:PVC how to deal with leaking water in the upper opening of three pipe joint of launching pipe?
To buy a bottle of UPVC dedicated glue, and then go to the production of PVC pipe manufacturers, where they want a little PVC resin powder
Q:Do you need adhesive for the sleeve joint of PVC wire pipe?
It is, in theory, but very rarely used. Wiring can be done without adhesive.
Q:What's the meaning of the plumbing PVC pipe joint specification "1/2" "X12" and "1/2" "x18"?
Indicates that the joint is 1/2 of the wire (that is, the 15 wire), and the length of the wire is 12 18mm
Q:Hot tap water pipe joint leakage, what method can be repaired?
The original hot connection place cut, a new joint with a pipe section, and then pick up
Q:Apart from the air-conditioning, the high-pressure pipe is not tight enough. What shall I do?
The position of the station is wrong, the output is not working / the spanner angle is not right... The most simple, is to find a major wrench with a long handle and then force that, if the screw is not open, it may break pipe head, we should pay more attention to the....
Q:110 degree PVC pipe joint
The PVC pipe can be changed from two to three elbows, and try more than 45,35 meters of pipe can be installed according to the slope of 1%, the specific depends on the situation, if the flow is larger, but also with construction conditions, it is recommended that the slope is a little larger.
Q:Connect with stainless steel tube with 304 stainless steel clip type pipe joint,
I personally think that the installation problem, that is, the card sleeve and steel pipe only after installation to reach the sealing effect, the installation quality can not meet the design pressure requirements.To avoid this situation, it is recommended that after installation 1.25 times higher than the design pressure test, test pressure can be put into use
Q:Can the sleeve type pipe joint be disassembled and assembled several times?
Some domestic manufacturers in Europe and the United States is the sleeve type pipe joint suppliers, their structure can be repeated disassembly; but some connector is a one-time pressure deformation, the joint group cannot be used repeatedly, or at least need to replace the components outside the card of the pipe, and the sealing surface of the belt assembly still need to check the qualified talents use up a nut by repeating
