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:Why does the air conditioner outdoor pipe joint freeze and freeze in case of refrigeration?
Normal: a thin tube (pressure pipe) cool or lukewarm, thick tube (tube) cool or cold dew.
Q:Hydraulic jointWho knows the hydraulic connection "3/8*25.4=9.525" refers to the connection?
3/8 is an English name. We call it "10 connectors", referring to the outer diameter of this joint.
Q:What is a reinforced pipe joint?
It has a certain mechanical strength and good shock absorption. It is suitable for making parts under moderate stress, working parts in weak corrosive environment, such as cover, bearing seat, valve body, hand wheel and so onThe main purpose of strengthening the pipe joint is to connect, install and maintain conveniently.
Q:Inside and outside the threaded joint, one end of the internal thread (G),
The cylindrical internal thread and the taper outer thread form a column / cone fit; the taper internal thread and the taper outer thread form the cone / cone matching.
Q:PVC pipe joint leakage how to do?
Solution of water leakage in sewer pipe:1, if the water is PVC, will be able to buy a PVC pipe to pick, put the tube cut broken, the first set of interface end into the pipe, the other end of the cut position coincides with a hole in the interface of Qi Ping, making it just to straighten. Then send directly to this end, the two ends have a certain cross then distance (length) and then put it down, with lateral water pipes and the two in the PVC at both ends of the inner side direct glue.2, you can buy waterproof tape to repair the water pipe, it is entangled with the line, and then mortar, waterproof agent and cement on it.3, can not handle, it is better to find a professional company.
Q:How tight is the gas pipe joint?
A section of the pipeline connected with the household is mainly connected from the pipe joint to the ends of the gas cooker. The most common is the use of oil resistant, pressure resistant reinforced plastic pipe. The plastic pipe shall be inserted into the pipe joint so long as to avoid leakage.The plastic tube is inserted, should use the hose clamps or other hoop, or wire tie, then use soap (do not use fire to leak detection)
Q:Infusion, infusion tube joints fall off and immediately connected, lost three or four minutes will have an impact?
There is no air on the upper end of the infusion pipe, the joint is not polluted, and immediately after the falling off, the problem is not too great. The switch on the upper end of the infusion tube is not closed. The liquid medicine can be discharged directly and immediately after falling off, so there is nothing wrong with it.
Q:Quick plug and card sleeve joint sealing which good?
1, small;2, standard type;3, metal type;4, stainless steel type;5, flame retardant;6, compound type;7 drum type joint body combination;
Q:What's the hydraulic pipe joint material?
Selection of pipe joints, the minimum is equal to the entire hydraulic system working state of the maximum working pressure setting the maximum working pressure for each joint, not only to consider the pump outlet pressure, also consider starting pressure relief valve. Therefore, in the design of complex hydraulic pipeline, the actual pressure is best measured by field measurements. The system operating pressure has been fixed, so the maximum working pressure of each selected pipe joint shall be checked.The maximum working pressure of the pipe joint can be changed by different sealing methods or according to the change of temperature: similarly, if the pipe joint chooses the elastic seal, it will get higher working pressure than the rigid seal.International standard set 4 times insurance coefficient, the reason is the practice of design thinking, the error of pipe joint device and equipment operation process may appear, the working condition of the system stability, in order to guarantee the system not paralyzed when in operation, so the insurance coefficient of the nominal pressure of the high.
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.
