The pipe spool fabrication line has unique structure, high degree of automation, convenient operation, stable and reliable continuous production. The pipes produced by this pipe spool fabrication line have moderate rigidity, strength, good flexibility, creep resistance, environmental stress cracking resistance and good thermal welding performance, and have become the first choice for urban gas pipelines and outdoor water supply pipes. However, there are still some problems when using the pipe spool fabrication line.
Here is the content list:
l Failure of the production line and corresponding measures.
l Computer system failure and corresponding measures.
l Pipe spool fabrication line failure and corresponding measures.
l The outer surface of the pipe spool fabrication line is rough
① Adjust the pipe spool fabrication line of process temperature: reduce the cooling water temperature, the best cooling water temperature of the PE pipe is 20~25℃
② Check whether the waterway is blocked or the water pressure is insufficient;
③ Check whether the heating ring of the barrel, head, etc. is damaged;
④ Adjust the water flow of the sizing sleeve;
⑤ Please consult the raw material supplier for the raw material parameters of the batch;
⑥ Check the mold core temperature, if it is higher than the die temperature, reduce the mold core temperature;
⑦ Clean the mold;
l Grooves appear on the outer surface of the plastic pipe
① Adjust the water outlet pressure of the sizing sleeve, and balance the water output;
② Adjust the nozzle angle in the vacuum forming box to evenly cool the pipeline;
③ Check the mold, sizing sleeve, cutting machine and other hardware for debris and burrs;
l There is a jitter ring inside the pipe spool fabrication line
① Adjust the water outlet of the sizing sleeve to make it even.
② Adjust the vacuum degree of the second chamber so that the vacuum degree of the rear chamber is slightly higher than that of the front chamber;
③ Check whether the vacuum seal is too tight;
④ Check whether the tractor is shaking;
⑤ Check whether the host output is even;
l The outer diameter of the pipe spool fabrication line is out of tolerance
① Adjust the vacuum to change the size of the outer circle;

③ Disassemble the mold, check whether the screws in the mold are loose, and then tighten it again;
Computer system failure
When the computer is turned on or running, pipe spool fabrication line is not allowed to enter the test state.
l Problem 1: The tensile strength and toughness are poor. The tensile strength curve of pipe spool fabrication line should have obvious yield strength and greater elongation, while poor plastic pipes are usually fragile, low elongation and easy to break.
l Problem 2: Poor impact resistance. According to the GB/T5836.1-92 standard, the drop hammer impact test was tested. After years of testing, it was found that the pass rate was only less than 50%, and many pipe spool fabrication line were even damaged by 10 times.
l Problem 3: The softening temperature is low and it is easy to deform after being heated. It is shown in the test performance, that is, the Vicat softening temperature is relatively low (less than 79). Some manufacturers only increase the amount of filler during the compounding process to increase the softening temperature.
This can indeed increase the softening temperature, but will greatly reduce the other properties of the pipe, especially impact resistance, tensile strength and toughness. Therefore, in order to increase the softening temperature without reducing or seldom reducing other properties, attention must be paid to the selection of additives, the ratio of raw materials, the production process and the production machinery, Can not be taken lightly.
Pipe spool fabrication line is tested in accordance with the national standard GB/T10002.1-1996, and its hydraulic inspection performance standard value requirements are relatively high, which puts forward high requirements for enterprises that produce pipe spool fabrication line. The eccentricity problem is one of the common plastic pipe problems, which will result in large uneven wall thickness of the produced plastic pipes, which not only causes waste of raw materials, but also makes it difficult for the water pressure test performance to meet the requirements.
The operation of the pipe spool fabrication line has a great impact. Therefore, this requires manufacturers not only to match the materials well, but also to install online testing equipment so that qualified companies can adjust the size deviation of the plastic pipe at any time.
Because the pipe spool fabrication line is very smart, pipe spools are used in almost all industrial applications. The specific part of the pipe spool fabrication line can be arranged in various sizes and shapes of the target application area. Therefore, the most common application areas of tubing can be divided into: household applications, industrial applications (factories), medical applications and construction applications.

The pipe spool fabrication line is a component that can be welded or assembled to each other to form the entire pipeline system. Before discussing the application of pipe spool fabrication line, it is best to start with the understanding that the pipe is a straight longitudinal pipe used to transport fluid.
However, spools are pipes with complex shapes composed of different sections. They are used for prefabricated parts produced by pipe spool fabrication line, including shot blasting machines, pipe cutting machines, beveling machines, pipe fitting machines, pipe welding machines and other equipment.
Use of pipe spool fabrication line
① Residential use: cold, hot water and heating for houses and villas.
② Public buildings: water supply and floor radiant heating for public buildings such as office buildings, markets, theaters, and military camps.
③ Transportation facilities: piping for airports, passenger stations, parking lots, garages, and highways.
④ For animals and plants: piping for zoos, botanical gardens, greenhouses, and chicken farms.
⑤ Sports facilities: cold and hot water pipes for swimming pools and saunas.

⑫ Easy and fast construction
The pipe spool fabrication line is a component that can be welded or assembled to each other to form the entire pipeline system. In modern engineering applications, the pipe spool fabrication line is used to transport required materials almost anywhere.
Domestic applications: Most domestic applications use steel pipe systems because of their mechanical durability and high corrosion resistance. The material of the short tube is domestic (domestic) stainless steel. The entire piping system of the house consists of stainless steel pipes and spools.
Industrial applications: Energy and certain raw materials are transported through the use of complex spool systems. Factories usually produce by-products such as exhaust gas and liquids. These exhaust gases and liquids must be removed from the production area. Therefore, these substances can also be removed through the pipeline system. In industries where space constraints can cause difficulties, some complex spool systems are the first choice. In addition, extremely long pipeline systems are also used for energy (oil, natural gas, etc.) transportation. These extra-long pipe systems have spool sections of various sizes and shapes.
Medical applications: Simple pipe spool fabrication line are even used in surgical and dental applications. The biocompatibility of the tubing used is the most important criterion in medical applications. Therefore, compatible pipe spool fabrication lines are used for bone healing or medical processing applications.
Construction applications: Pipes are one of the most common areas of use. For high strength, the required pipe material is usually selected as steel. When the foundation of the building is too weak to support the building, steel pipes are used as the support element of the building. In some architectural works, only complex spool systems are used for construction. The pipe spool fabrication line is also used to build ships and refineries.
Pipe spool fabrication line components can be divided into large and small straight pipes and accessories. In addition, accessories can also be divided into flanges, tees and elbows. These different components are widely used for other needs.
The pipe spool fabrication line must meet some essential requirements to generate effective fluid flow. Therefore, the complex pipe spool fabrication line must have high flexibility, cycle life, pressure rating, chemical resistance and corrosion resistance.
For example, pipe spool fabrication lines are commonly used in oil refineries and crude oil transportation lines. The sharp bend of the pipeline will change the type of oil flow from laminar to turbulent. Therefore, the turbulence of oil may cause corrosion and corrosion of the system.
These corrosion problems can be identified from the horseshoe-shaped cracks. Since these crevices remove material from the surface, they can cause leakage in the pipe spool fabrication line and are harmful to oil pipelines. Therefore, for the required pipe spool fabrication line application, the correct selection of materials and components is essential to the safety of the system!If you want to know more about high-quality tank welding machine products, you can also contact us at any time.
