You may have seen some descriptions of Krah Pipes, such as how they are excellent for preventing liquid corrosion of Pipes, but do you know what the Krah Pipes production line is? How does it work?
1 What is the joint production technology for Krah Pipes?
2 How flexible is the Krah Pipes?
3 How long is the life of Krah Pipes?
Most Krah Pipes production lines use integrated sockets and sockets.
These apply to the connection technologies listed below. As various tests and decades of experience have shown, the connecting parts of the piping system are often the most vulnerable. Here, the pipes are mostly exposed to possible leaks. Krah Pipes production line provides a well-known connection method for large-scale applications, eliminating these problems by ensuring stable and uniform Pipes.
Fused. Most importantly, fusion bonding is a favorite of all pipe connection systems. Krah GmbH has successfully developed this technique for large diameter pipes.
The fuse wiring is included in the socket of the Krah Pipes. After the socket and socket of the two pipes are connected together, the two ends (socket and plug) are welded together by heating the wire with the help of a special welding device. This connection technology allows for piping to be installed in such a short time. A 72m pipe with a diameter of 1200 mm can be installed in 8 hours with only one welding equipment. Installation speed now depends on trench engineering.
Extrusion welding. Pipes and/or fittings should be connected through sockets and sockets. Therefore, the two tube ends are connected by means of an extrusion welding device.
Connection methods can be performed internally or/and externally in HDPE Spiral Profile Pipe. This connection is most suitable for low pressure gravity pipes and manholes. Welding must be done according to DVS 2207.
V seam extrusion welding. Pipes and fittings are connected with the help of an extrusion - welded extruder.
The outside of both ends is chamfered. As a result, the weld looks like a "V". Socket connections are not normally used. Welding must be done according to DVS 2207.
Butt fusion. Pipes and fittings are connected with the help of a heating element butt welder. The ends of Pipes and fittings in the Krah Pipes production line were butt welded.
This connection method is only applicable to pipes and fittings with maximum wall thickness of 150 mm and diameters ranging from DN/ID 300 mm to DN/ID 2500 mm. Welding must be done according to DVS 2207.
Flange connection. The ends of pipes and fittings are connected with steel flanges and rubber gaskets.
Depending on the type of pipe, the flange adapter is made entirely from the pipe, or the flange can be supplied as a separate accessory. This connection method is mainly used for high seas discharge application and tank connection. The greatest advantage of this connection is the convenience of separation.
EPDM seals. The Krah Pipes system includes a rugged common socket and socket with integrated EPDM seals.
The minimum wall thickness of the casing conforms to EN13476. In addition, the ring stiffness of the casing plus the ring stiffness of the casing is higher than the ring stiffness of the pipe.
Elastic pipes can respond to changes in the environment. Because of the deformation behavior, the load is distributed around it and the force acting on the pipe is reduced. In a very short time, the area around the pipe will be balanced and the deformation will stop. Plastic tube on static.
The response of the load is very flexible, and the load is not concentrated in the pipe, but transferred to the surrounding soil. HDPE Spiral Profile Pipe still work when other rigid Pipes have broken or cracked.
Even in the case of deformation, the system remains absolutely resistant to penetration and seepage.
Because the Pipes are formed externally, these profiles protect the Krah Pipes in the soil a little.
There is almost no axial extension in the pipe. HDPE Spiral Profile Pipe are almost unaffected by temperature changes.
Pipes made from polyethylene and polypropylene have considerable advantages over concrete, steel, toughness and other pipes.
Due to its material, the Krah tube has a high elongation at break ratio. The Krah Pipe deforms in accordance with the motion of the earth and does not have any fracture or crack and therefore the movement of the pipe.
It won't be seriously affected. Once the overload and soil movement is over, the pipe returns to its original state and position.
Another advantage is flexibility. Even in areas most affected by earthquakes, our pipelines are almost impervious to damage compared with those made of other materials. Although the Krah Pipes are flexible, they have a great carrying capacity and therefore
They also apply to roadworks.
Full Krah Pipes for gravity and low pressure applications have a life span of 100 years.
Basically every component is designed for 50 years of complete and constant load.
Tao stability is designed for 100 years, including calculated safety margin. Achieve stability - under constant load, in our case we have additional safety due to the use of polyolefin. Once the load is released, time starts again, and you gain additional security again.
Now that you have seen the explanation of the Krah Pipes production line, you should have a general understanding of why the HDPE Spiral Profile Pipe have such excellent capacity and flexibility. If you need a solid, high-quality Krah Pipe that is rigorously tested, Eagle Machinery can provide you with the best products.
