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:Joint type of pipe joint
G is the pipe thread collectively (Guan), 55, 60 degrees division is functional, commonly known as tube round. The thread is machined from a cylindrical surface.ZG is a commonly known as cone, cone thread processing, pipe joint is generally the domestic old standard thread marked Rc thread RMetric threads are represented by pitch, and American and British threads are expressed in thread per inch. This is their greatest difference,Metric thread is 60 degrees equilateral tooth type, thread is isosceles tooth type thread 55 degrees, 60 degrees.Metric units for metric threads; British and American systems.Pipe thread is mainly used for pipe connection, the internal and external threads are closely matched with straight pipe and cone pipe two kinds. Nominal diameter refers to the diameter of the pipe to be connected. Obviously, the diameter of the thread is larger than the nominal diameter.1/4, 1/2, 1/8 is the nominal diameter of inch inch, inch in inches.
Q:Inside and outside the threaded joint, one end of the internal thread (G),
G is the British characteristic of non hermetic cylindrical thread.The thread tagging you can refer to "metric, American and English standard thread Standard Handbook (Third Edition)".
Q:May I ask what material EN39 is? Used to make a threaded pipe joint
Groove connection: This is the most advanced connection mode at present. There are two two connecting pipes, valves, or pipes and valves that are connected by clamps. In the outer pipe or valve connecting end have an annular groove manufactured according to the standard, when connected with a supporting clamp. Site construction, installation and disassembly are very convenient and quick. Not only the seal is reliable, but also saves time and material. It has incomparable advantages in large caliber connection.
Q:PPR pipe joints did not plug in the melt, in the end will leak?
6, the pipe and fittings into the fuse, heating according to the designated time;7, after heating, remove the pipe and pipe fittings, immediately connected in the pipe and pipe fittings connected with timely, if the position is wrong, can do a certain period of time in the mediation, but shall not exceed 5 degrees across the rotation angle;8, the connection is completed, both hands must grip the pipe and pipe fittings, to connect the rich cooling time, cooling to a certain extent, you can let go, continuous arrangement of the next section of the pipe.Three, after the completion of the pipe connection, should be on the wall or ground with colored paint to show the pipe position, to prevent the two decoration damage to the pipeline. If the water supply pipe is concealed, a strong supporting point shall be made to go through the floor so as to prevent the standpipe from accumulating and flexing, and to produce displacement stress at the uppermost branch pipe and cause damage to the branch pipe.
Q:How do you disconnect the PVC pipe joint that has been glued?
A sticky PVC pipe joint is not normally open. Only cut off and re connect.Do you know?
Q:What is pressing type pipe joint
A joint body core and buckling nut strictly, crimping connector still belongs to the soft seal
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:Can the pneumatic pipe connection be carried through the water?
There are two types of pneumatic couplings, the quick couplings are not available, and the other can be inserted into the pipe and locked outside with the nut
Q:What do you mean by "s" in the standard of pipe joint?
Did the landlord say "S" and "L"? S is a high voltage application, for example, at the P port. L is low voltage applications, generally used only in the oil return.
Q:The pipe joint model is 1/2 "-14 teeth / inch"
British thread is the size of the thread in English, marked by the shape of cylindrical, cone two, according to the tooth type angle of 55 degrees, 60 degrees, two kinds
