Our company is a professional research and development, manufacturing heat-wrapped structure wall reinforcement tube (carat tube) production line. The company has complete and advanced technology research and development, production and product testing related systems, to provide customers with a complete set of extrusion technology turnkey project. The main products are carat tube, carat tube production line, polypropylene polybutylene seamless winding tank production line.We supply machine to produce the profiled pipe making machine, manhole from DN/ID300mm to DN/ID 4000mm. The main applications for the final profiled pipe products are non-pressure applications like drain, storm drain, sewer piping systems and chemical storage tanks as well as low-pressure applications like irrigation systems.
The great advantage of this production technology is that production is very flexible that one HDPE/PP profiled pipe machine can produce the pipe from DN300 to DN4000 and changing time is very short to change the production from DN300 to DN4000mm, also can produce different type and ring stiffness classes pipe from SN2 to SN16.
The carat tube, also known as the high-density polyethylene structure wall hot-wound tube, is a new type of profiled wall tube made of high-density polyethylene hot-wound forming process. The product uses high-density polyethylene resin (HDPE) as raw material, PP or PE bellows as auxiliary support tube, and high-density polyethylene large-diameter wound reinforced tube produced by hot-wound forming process. Because this kind of pipeline was originally introduced by the domestic company from the German carat company, it is commonly known as the carat tube in China.
The official name of this pipe in China is: high-density polyethylene structural wall hot-wound pipe, the national standard is GB/T 19472. 2-2004 B-type structural wall pipe. The product is an environmentally safe product with the advantages of light weight, strong pressure bearing capacity, high interface quality, long life, corrosion resistance, high ring stiffness and convenient construction. It is widely used in urban water supply, drainage and long distance water transportation. And farmland irrigation and other projects. The caliber is from DN300-DN4000. The pipe is light in weight and good in overall flexibility. It is the main pipe of choice for buried sewage drainage.
The main advantages are: light weight: the hot structural wall winding tube is very light, so it can be easily transported during the installation process. The crane can be used in many engineering sites, thus reducing the installation cost; the ring flexibility is high: The carat tube has a very high ring flexibility. When the force is applied, the carat tube will transfer the load to the surrounding soil due to the deformation of the force. The soil will exert the opposite force and bear the load on the carat tube. The steel pipe (cement pipe) will bear the force generated by the load when the force is applied, and the force cannot be transmitted to the surrounding soil through the deformation.
When the load is too large, permanent deformation and damage will occur; the connection is convenient and reliable: The pipe will produce the socket in the production process, so it can be connected by electric fusion or rubber ring. Ensure that the pipe is sealed without leakage after installation; the installation is convenient and fast: the carat tube is light in weight, generally 6 meters in length, and the installation is very simple. After the groove is dug, the pipe is placed in the groove of the groove machine, and each pipe can pass differently.
Connection technology for connection; transportation: the carat tube is light in weight, the pipes of different diameters can be set together, so the freight is low and the transportation is very easy; chemical corrosion resistance: the carat tube and the matching pipe fittings are made of the same material (generally high density) Polyethylene or polypropylene, which is resistant to attack by a variety of chemical media and does not require preservative treatment.
In addition, it does not promote the growth of algae, bacteria or fungi, and has a service life of 100 years; the inner wall roughness is low: the inner wall of the carat is smooth and does not scale. The carton capacity of the same diameter, the same length and the same pressure is about 20% larger than that of the cement pipe, so the economic advantage is obvious; the wear resistance is good: the carat tube is made of high-density polyethylene or polypropylene. The wear resistance of the two materials far exceeds other materials such as cement, steel, etc.; environmentally friendly and recyclable: coiled pipe material, high density polyethylene and polypropylene can be recycled 100%.
However, the production of such a pipe requires a machine-shaped pipe manufacturing machine, so at the same time, the cost of the HDPE/PP Profiled Pipe Machine has become a hot topic of discussion among major players in the industry.
Regarding the KRAH Pipes Production Line , a company in the industry has developed a new generation of Bauku Winded Profile Pipes Machine -Eagle Machinery Co., shown the largest DN/ID3500 HDPE spiral profile pipe at Chinaplas 2018 in Shanghai.
Eagle Machinery Co. developed new generation HDPE/PP spiral profile wounded pipe machine. This machine can produce the HDPE profile spiral corrugated pipe from DN200 to DN4000mm on one machine. The production is very flexible. It just takes 5 to 15 minutes to change one size to another size, and it can produce the HDPE spiral profile pipe with different ring stiffness from SN2 to SN32.
The HDPE spiral profile pipe is with special profile design. The profiled pipe making machine is confirmed with international standard such as EN13476, DIN16961, ASTM F894, it is very light, long service life of 100years.This machine is equipped high output extruder what can be customized. The output is from 600kg/h to 1500kg/h. But its cost is not impressive .
Therefore, the cost estimate for profiled pipe making machine needs further study.
