What are the available C70600 Pipe Types?
C70600 pipes are available in two types.
These are:
· Seamless C70600 Pipes
The production of seamless C70600 pipes requires the use of methods such as extrusion, forging, mandrel mill or rolling mills.
The manufacturing methods create seamless C70600 pipes that are smooth with no joints.
As a result, these pipes offer better leakproof characteristics compared to welded C70600 pipes.
These pipes have uniform design and strength along their cross-section, which facilitate fluid flow.
These pipes are durable due to the absence of joints compared to C70600 pipes.
Seamless C70600 pipes are pricey than welded C70600 pipes.
However, they have a low maintenance cost.
The operating pressure and temperature of systems that use these pipes are relatively high.
· Welded C70600 Pipes
Welded C70600 pipes feature joints along its surface.
This makes the surface to have uneven strength and design.
Fabrication processes of C70600 pipes involve circular section forging.
This is through methods like continuous rolling, plate rolling or point pressing.
Welding of the circular section follows.
Welding can be through a high-frequency method, submerging arc welding method or electric resistance method.
Applications whose fluid flows is at low pressure and have low temperature make use of these pipes due to their uneven strength and structure.
Though they are cheap compared to seamless C70600 pipes, they have a high maintenance cost.
This is due to leaking, which is a common weakness.
C70600 Pipes use which Pipe Fittings?
C70600 can use the following copper nickel pipe fittings:
Copper nickel pipe fitting
- 180-degree fitting
- Stub end fitting
- Endcap fitting
- Saddle pipe fitting

What makes C70600 Pipes different from CuNi 70/30 Pipes?
C70600 Pipe
The chemical compounds have varying quantities in C70600 pipes and CuNi 70/30 pipes.
In C70600 copper is the primary compound at 90% while Nickel is 10%.
30% Nickel and 70% copper constitute CuNi 70/30.
Besides, they have other elements such as manganese and iron with CuNi 70/30 pipes having more of these two elements.
C70600 pipes are cheaper than CuNi 70/30 pipes though their resistivity to thermal and electrical conduction is lower than that of CuNi 70/30 pipes.
Due to the large amounts of manganese and iron content, CuNi 70/30 pipes are stronger than C70600 pipes.
High salty applications make use of CuNi 70/30 pipes while applications such as desalination plants, marine plants and power plants use C70600 pipes.
C70600 pipes use which CuNi Flanges?
CuNi Pipe Flange
Among the CuNi flanges that C70600 pipes use include:
· CuNi Composite Flange
CuNi composite flange comprises of the inner and outer part.
Carbon steel makes up the inner part known as Collar end while CuNi makes up the outer part.
C70600 pipes that have low operating pressure and temperature uses these flanges.
Example of piping applications with these pipes and flanges are offshore oil plants, power generating industries and sewerage plants.
· CuNi Threaded Flange
The characteristics of CuNi threaded flange include hollowness and ends that are threaded.
You can either have a male threaded end or female threaded end.
When connecting a threaded flange, the male end of your flange connects to the female end of your C7070 pipe.
Similarly, the female end of your flange connects to the male end of your C70600 pipes.
The connection is simple.
Once you have the right size of CuNi threaded flange for your C70600 pipe, you just screw it tightly into your pipeline.
C70600 pipes with high pressure fluid flow while their diameter is small uses these flanges.
Also, you can use CuNi threaded flanges in applications that are easily flammable when you apply welding choose to use CuNI threaded flanges.
Such applications include power generating plants, water piping and shipbuilding.
· CuNi Socket Weld Flange
CuNi socket weld flange has a bore having shoulders called a recessed segment or a counterbore.
The shoulder helps in measuring how deep you need to install your pipe.
There are two holes in this type of flange.
There is the counterbore as the first hole whose diameter is larger compared to C70600 pipe you are installing.
There is the second hole whose diameter is similar to your C70600 pipe’s diameter.
The pipes which use this flange include those that cannot use CuNi threaded pipes since there is fluctuation in the operating temperature and pressure.
Using CuNi threaded pipes in such operating temperature and pressure can lead to leakages.
Its use is also common in applications where the proper alignment of the C70600 piping is mandatory.
CuNi socket weld flange is also useful in C70600 pipes that are difficult to weld the interior joint section.
· CuNi Blind Flange
There are no holes on the surface for this kind of CuNi flange.
This facilitates fluid flowing through these fittings.
The only holes present in these CuNi blind flange are holes for bolting it on your C70600 pipes.
Applications that require cleaning or repair use these pipes.
Other applications include separating a tool or section of C70600 piping system.

You can have a C70600 male threaded end design which should fit into a female threaded pipe fitting.
It can also be a female threaded end design which should fit into a male threaded pipe fitting.
The difference between the two types is the direction of the cuttings.
In male threaded, the cutting heads out to the external surface of the pipe.
Also, in a female threaded, the cuttings head into the internal surface of the pipe.
· Plain End Design
The end cutting of a Plain end design is right-angled to that of your C7600 pipe run.
It is ideal for use in connections such as slip-on flange or socket weld.
· Bevelled End Design
Bevelled end design features an angle between a perpendicular plane along the surface and your C70600 pipe edges.
Ideally, the angle is 37.5 degrees.
However, you can have customized angles depending on the C70600 pipe requirements.

· Smooth Finish
This surface finish leaves your pipe’s surface polished.
It uses a round machine that has a radius of 0.8mm to create a zigzag groove with a depth of 0.05mm.
The machine rotates at a speed of 0.3mm/cycle.
· Spiral Serrated Finish
A rectilinear machine creates non-ending twist grooves resulting in a “V” layout with 45 degrees.
The only difference between a spiral serrated surface finish and stock surface finish is the “V” layout in spiral serrated surface finish option.
· Coldwater Finish
Applying Coldwater finish on your C70600 pipes leaves them with a polished mirror-like surface.
This surface finish is applicable if you are considering connecting two metal planes that don’t need the use of a gasket.
· Stock Finish
A round-shaped machine is responsible for the creation of a gasket that has spiral grooves.
This radius of this machine is 16milimeters, and its cycle for each revolution is 0.8 mm.
