Product Details

Composite Weld Neck Flanges

Shihang , as one of the world class copper nickel flanges manufacturer and supplier , also produce copper nickel composite weld neck flanges.

Shihang composite weld neck flange are made of copper nickel inner flanges , also named as copper nickel collar , copper nickel stub end, and carbon steel outer flange , also name loose flange or backing flange.

In general, use composite weld neck flanges in one of three situations:

  • Cost savings. When the material of the pipe is special and the price is expensive, welding the flange of the same material is costly.
  • Inconvenient to weld or inconvenient to process or require high strength.
  • Easy to construction.

Disadvantages of using a flat weld ring loose flange:

  • The pressure is low. The pressure on shipment building is low ,so composite weld neck flanges are very popular on shipment building.
  • The strength of the solder ring is low

Shihang composite weld neck flange are made of copper nickel inner flanges , also named as copper nickel collar , copper nickel stub end, and carbon steel outer flange , also name loose flange or backing flange.

Composite slip on flanges are similar as composite weld neck flanges.

The different between composite slip on flanges and composite weld neck is the connection with the copper nickel pipes, butt weld and slip on weld.

Copper Nickel Weld Neck Flanges

Shihang , as one of the world class copper nickel flanges manufacturer and supplier , also produce copper nickel weld neck flanges.

Shihang copper nickel weld neck flanges are a kind of copper nickel flanges, which refers to a flange with a weld neck and transition of a round pipe and welded to the pipe.

The difference between copper nickel weld neck flanges and copper nickel slip on flange is that there is a long, inclined high-necked flange between the flange and the pipe-welded part of the flange, and the wall thickness of this high-necked part. The gradual transition to the wall thickness in the height direction improves the discontinuity of the stress and thus increases the flange strength.

Shihang copper nickel weld neck flanges are mainly used in harsh working conditions, such as pipes where the pressure or temperature fluctuates greatly, such as high temperature and high pressure, when the stress on the flange is increased due to thermal expansion of the pipe or other loads. Subzero temperature pipeline. The high-necked flange is not easy to be deformed, sealed, and widely used. The nominal pressure is about PN1.0MPa~PN25.0MPa.

Shihang copper nickel weld neck flanges can be divided into the following types according to the sealing surface: flat face flanges, raised face flanges.

Copper nickel weld neck flange application scope

Shihang copper nickel weld neck flanges are not easy to be deformed, sealed, and widely used. It has corresponding rigidity and elasticity requirements and reasonable butt weld thinning transition. The distance from the weld joint to the joint surface is large, and the joint surface is not deformed by the welding temperature.

It takes more complicated Sludge body structure, suitable for pipelines with high pressure or temperature fluctuations or high temperature, high pressure and low temperature pipelines, generally used for the connection of pipelines and valves with PN greater than 10 bar; also used for conveying expensive, flammable and explosive Medium on the pipeline.

Copper Nickel Slip On Flanges

Shihang , as one of the world class copper nickel flanges manufacturer and supplier , also produce copper nickel slip on flanges.

Copper nickel slip on flanges has a low neck height, which improves the rigidity and load-bearing capacity of the copper nickel flange. Compared with copper nickel weld neck flanges, the welding work is large, and it will cost more copper nickel welding rods, and the high temperature and high pressure and repeated bending and temperature fluctuations cannot be avoided.

However, the on-site installation is more convenient, and the welding seam kneading process can be omitted , so the copper nickel slip on flanges are popular.

Copper Nickel Socket Weld Flanges

Shihang , as one of the world class copper nickel flanges manufacturer and supplier , also produce copper nickel socket weld flanges.

Shihang copper nickel socket flange’s  basic shape is the same as copper nickel slip on flanges. That is, a certain bore hole is formed in the inner hole of the copper nickel flange, and the pipe is inserted into the bore hole and welded. Welding a circle of welds on the back of the flange, due to gaps between the socket flange and the groove, easy to produce corrosion, if a seam is welded inside to avoid such corrosion.

Shihang copper nickel socket weld flanges welded on both inner and outer sides have a fatigue strength that is 5% greater than copper nickel slip on flanges and the same static strength. When using copper nickel socket weld flange, its inner diameter needs to be the same as the inner diameter of the pipe. The socket weld flange is only suitable for pipes with a nominal diameter of 150 ( 4 inch ) or less.

Copper Nickel Threaded Flanges

Shihang , as one of the world class copper nickel flanges manufacturer and supplier , also produce copper nickel threaded flanges.

Shihang copper nickel threaded flanges are made by machining the inner bore of a flange into a pipe thread, and are connected to a threaded pipe to make a connection. This is a non-welding flange. Compared with the copper nickel weld neck flanges and copper nickel slip on flanges, the copper nickel threaded flanges are easy to install and maintain, and can be used on pipelines that are not allowed to be welded on site. But in the pipeline temperature changes sharply or the temperature is higher than 20 °C below -45 °C conditions. We do not recommend using the copper nickel threaded flange to prevent leakage.

Threaded Type: NPT, BSPT

The sealing surface of the copper nickel threaded flange has two types, raised face and flat face. Take into account the structural characteristics of the copper nickel threaded flange. Therefore, it is not suitable for flammable/explosive and highly hazardous and extremely hazardous applications. Nuclear pressure is small, such as air-conditioning water systems, etc., which can be used safely.

Copper Nickel Blind Flanges

Shihang , as one of the world class copper nickel flanges manufacturer and supplier , also produce copper nickel blind flanges.

The middle of the blank flange is solid, surrounded by bolt holes, copper nickel  blind flanges can be either flat or raised. In short, the purpose of copper nickel blind flangs is to block the copper nickel pipeline, it is the material inside the pipe will not overflow, generally used at the end of the water supply branch. There is a temporary part of the pipe segment to be used for temporary blockade, some directly with the valve, some of the original pipe is now unused, use copper nickel copper nickel blind flanges.
