Product Description:

Steel Pipe Fittings Butt-Welding Concentric reducers

Features standards and products of our Butt-Welding Concentric reducers:

Features of Butt-Welding Concentric reducers:

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 Concentric reducers:

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 is the difference between the pipe and the pipe joint?
Two, plastic pipe type 1, PVC (PVC-U) plastic wire pipe (hard tube), 2 and PE threading pipe (winding hose) 3, plastic bellows (flame retardant bellows, wire harness casing, high density bellows, high temperature protective casing, etc.)
Q:What's the difference between the half pipe joint and the branch seat?
The 2. branch pipe seat is widely used abroad in recent years, the branch for strengthening pipe connection, to replace the traditional use of different diameter three, reinforcing plate, strengthening pipe etc. branch connection type, which has the advantages of safety, lower cost, simple construction, improve media channel, standardization, series design has the advantages of convenient so, especially in high pressure, high temperature, large diameter and thick wall pipe is widely used, instead of the traditional branch connection method
Q:The expansion type pipe joint and the sleeve type pipe joint difference, everybody looks at the picture, this is belongs to that kind of?
This is the lock type pipe joint.The other two are not easy to describe.The sleeve type pipe joint is replaced quickly, but it is not as reliable as the locking joint of the lock type pipe joint.
Q:Can the pressure vessel pipe joint adopt G thread? Why?
The pipe thread is on the wall of the pipe for connecting threads. It has 55 degrees of unsealed pipe thread and 55 degree sealing pipe thread. The utility model is mainly used for the connection of pipelines, and the internal and external threads of the utility model are closely matched with two kinds of straight pipes and a conical pipe
Q:The difference between threaded pipe joint and grooved pipe joint
It is divided into: the wire connection and wire connection. If the two are double wire connection is in need of a two double wire transition; if between the two are: double wire connection is in need of a two double wire transition; if the two just one male and one female, and the thread and facilities, it is directly screwed on it is good.
Q:Can the pneumatic pipe connection be carried through the water?
Yes, but it will leak. Or do you need a special pipe joint?
Q:How to choose the connection mode of clamp type flexible pipe joint correctly
Steel ring clamp type flexible pipe joint with pipe end / short tube clamp type flexible pipe joint.Comparison of advantages and disadvantages between pipe end connection and steel ring connection:Butt welding of pipe ends adopts low welding technology
Q:Silicone gasket, rubber gasket, water pipe joint which is good?
Silicone gasket is also a rubber gasket, compared with the ordinary rubber gasket, it has better chemical stability
Q:Reinforced pipe joint,Used in chemical pipes
DN means the inner diameter, 25 is 25mm, and DN25 is "25 mm in diameter", length 300mm.
Q:PVC how to deal with leaking water in the upper opening of three pipe joint of launching pipe?
And then find a PVC or half or more than half pipe cut off, the segments cut using UPVC glue in crack (crack, wrap) dry, you can prevent Water Leakage, but the specific will leak, will see you trap technology.
