Advantages of PA threading corrugated pipe

1) It can withstand – 30 degrees cold and maintain good impact and toughness;

2) Good bending resistance and flexibility, and can be folded repeatedly at high frequency;

3) Capable of long-term high-temperature resistance of 150 ° C;

4) Good oil ester resistance, no cracking in contact with oil ester.

New energy vehicle harness bellows

PA nylon bellows have strong waterproof, flame retardant, corrosion and acid-base resistance. It is widely used in the new energy automobile industry and is mainly used in automobile harness assembly, including various automobile air conditioning pipeline protective sleeves, harness bellows, harness flame-retardant bellows, automobile ventilation pipes, drip pipes of refrigerated transportation vehicles, automobile harness pipes, automobile braking system protective sleeves, car oil and gas pipes, machine tool harness pipes and other automobile bellows and air conditioning drip pipes. Compared with metal hose, it has lower cost, smooth surface and easy installation. Due to the flexibility of PA nylon hose, it is easy to arrange on the whole vehicle; The application of nylon hose in automobile fuel pipeline can effectively reduce the weight and cost of the whole vehicle, and make the design of fuel pipeline standardized and universal.

PA nylon bellows has more advantages than metal hose in the field of new energy vehicles

PA nylon bellows has damping property: anti fatigue, impact resistance and not easy to deform. During assembly and use, it can withstand external impact without causing pipe loosening and fracture;

PA bellows is soft and easy to install: in the process of steel pipe wiring, some joints are added due to the influence of layout. In this way, unnecessary sealing contacts are added to increase the air leakage rate, and the bending radius of the pipeline is s樂威壯 mall, which increases the air resistance and prolongs the reaction time of the pipeline; No rust: the nylon bellows will not produce rust particles affecting the performance in the fuel pipeline system; The corrosion resistance of steel pipe, even if it is galvanized inside and outside, is limited, so it is difficult to ensure the cleanliness of the pipe system; Standardization and generalization of fuel pipeline design: in the production process of steel pipe, due to the accumulation of tolerance, it is difficult to assemble, poor connection and poor sealing, there are many steel pipe joints and supports, the design, trial production and production cycle is long, and it is difficult to be serialized, generalized and standardized.

Advantages of PE corrugated pipe

1) Corrosion resistance

2) The surface is smooth, the fluid resistance is small, and it is not easy to breed microorganisms

3) Not easy to heat deformation

The normal service ambient temperature of PE threading pipe is about – 15 ℃ ~ + 40 ℃. PE threading pipe has excellent mechanical properties and excellent corrosion resistance. In addition, the threading pipe has high compressive strength and working pressure of more than 2.5MPa. PE threading pipe has smooth surface, small fluid resistance, no scaling and is not suitable for breeding microorganisms. Moreover, the thermal expansion coefficient of threading pipe is small and does not shrink and deform, which is why it can be used so widely.

Product types of threading pipe

Threading pipe is a kind of hard rubber pipe, which can prevent corrosion, electric leakage and pipes for threading wires. As a whole, the product types of threading pipes can be divided into three categories: carbon steel threading pipes, plastic threading pipes and stainless steel threading pipes.

1) Carbon steel threading pipe

The carbon steel threading pipe is a wire and cable protection pipe made of Q235 seamless steel pipe. When the carbon steel threading pipe is connected with the straight pipe, the interface is protected with a sleeve, and then the pipe is connected with the threading pipe by welding. The purpose of this connection is to prevent the interface from being damaged by electric welding, so as to protect the wires and cables inside.

2) Plastic threading pipe

The full name of plastic threading pipe is “insulating electrical sleeve for construction”, that is, a kind of white hard PVC hose, which can prevent corrosion, electric leakage and wire threading. This product is of high quality, low price, beautiful and convenient. It is a good product.

3) Stainless steel conduit

Stainless steel wire pipe is made of 304 stainless steel or 301 stainless steel. It is mainly used as wire and cable protection pipe for wires, cables and automatic instrument signals. Stainless steel wire pipe is mainly used for the sensor line protection of precision optical ruler and industrial sensor line protection. Stainless steel wire pipe has good high temperature resistance, wear resistance, tensile resistance, flexibility and corrosion resistance.

Application fields of PE threading pipe:

PE threading pipe is generally used in indoor normal environments, or in places with high temperature, dust, vibration and fire risk. Of course, PE threading pipe can also be used in wet places.

However, it is worth noting that PE threading pipe can not be used in particularly humid places, and places with acid, alkali, salt and other corrosive substances and explosion hazards, because using in these places will make the threading pipe can not be used safely. Moreover, the threading pipe will be damaged.

Connection mode of PE threading pipe:

There are many connection modes for PE threading pipe, and the most classic and widely used installation mode is the traditional installation and connection mode. This connection method can make the epoxy plastic coating of threading pipe more effectively solve the corrosion of water transmission, buried and acid, alkali and salt to metal pipes, and the service life will be prolonged. Generally, this installation method is used, and its service life can reach more than 50 years, so now we will still choose the traditional installation method.

Application scope of PVC building threading pipe

Threading pipe is a kind of white hard PVC rubber pipe, which is used for anti-corrosion, anti electric leakage and threading wires. Now, PE bellows is commonly used as “electrical casing”, which is of high quality, low price, beautiful and convenient.

In the process of use, it mainly plays a protective role, protecting the wire from contacting with the cement, increasing the load of the wire, allowing the wire to dissipate heat and prolong the aging degree of the wire.

The buried wall of wires must be threaded through pipes. Generally, PVC threading pipes / PE threading pipes can be selected: affordable, bendable and good insulation performance. In fact, it’s very good for ordinary families to choose PVC threading pipe / PE threading pipe. Just choose strong ones. The simple way is to step on them with your feet. What won’t be crushed is good. Finally, a reminder: no matter what kind of threading pipe is used, the wire cannot have a joint in the pipe.

Dead lines should be avoided in circuit transformation: no matter how good the circuit quality is, it is difficult to ensure that there will be faults in the future, and the lines need to be replaced. At this time, it is very important that the wires buried in the wall can be easily pulled out and replaced. Therefore, in the construction of power transformation, it is necessary to avoid “dead lines” that cannot be pulled in the future.

It is used in normal indoor environment and places with high temperature, dust, vibration and fire risk. It can also be used in wet places. It shall not be used in particularly humid places with acid, alkali and salt corrosion and explosion hazards. The operating ambient temperature is – 15 ℃ ~ + 40 ℃. The threading pipe has excellent mechanical properties. Excellent corrosion resistance, high pressure resistance of threading pipe and working pressure exceeding 2.5MPa. The surface of the threading pipe is smooth, the fluid resistance is small, there is no scaling, and it is not suitable for breeding microorganisms. Small coefficient of thermal expansion, no shrinkage deformation. Traditional installation and connection mode. The epoxy plastic coating of threading pipe more effectively solves the corrosion of water transmission, buried and acid, alkali and salt to metal pipes, and the service life can reach more than 50 years

Conclusion:

Automobile Corrugated bundle pipe is often used in daily life to replace the original metal protective pipe, reduce cost, improve corrosion resistance, prolong service time, reduce weight, simple production process and less pollution. Based on the above advantages, the bellows of various materials will be the development prospect.
