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.

Q:Requirements for fire hose fittings
Main technical points of connection of fire water supply pipe4.3.1 General requirements(1) welding shall not be used when using hot galvanized steel pipes inside and outside the fire hydrant water supply system. The system pipe adopts the inner wall without corrosion, and the pipeline can be welded and connected, but the welding of the pipeline shall comply with the relevant requirements. Automatic sprinkler system (alarm valve), the pipe can not be welded, should be threaded, groove, pipe or flange connection.
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:Pokémon Black 2 What is a good fire type Pokemon I can add to my team and what move set would best suit it?
big bang! iiif you know what i mean. haha
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:What are the materials for fire hose fittings and connections? Can I use stainless steel 316?,
Material is pig iron castings. Stainless steel can be used.A fire pipe is a pipe material used for fire fighting, fire fighting equipment, equipment, fire fighting water, gas or other medium.As the fire pipe is often in the static state, and therefore more stringent requirements of the pipeline, the pipeline needs pressure, corrosion resistance, high temperature performance.
Q:how does the theory of relativity explain time-travel?
Copper pipe rots. You have to cut out the bad pipe an replace it with PVC.
Q:G1/8 "pipe joint end special sealing WD-B02 is what mean
The sealing effect is better than the traditional O ring. The elastomeric seals are used as axial static seals for threaded oil and screw ends, and the cross section remains almost constant at high pressure.
Q:How much is the monofilament of the 304 pipe joint?
This kind of pipe connection is very large, but the price depends mainly on how many sizes you want
Q:What is the reason that the rubber hose of the fire hose is flowing black oil?
This is the groove of the fire trench, the connection of the pipeline meets all the requirements and the quality is not satisfied. That is, the quality of aprons.
Q:What's the half pipe connection?
The half pipe connection essentially means that the branch pipe becomes larger when it is connected to the main pipe through the half pipe joint
