Silicone Glass Fiber Tube was first developed in the 1950s, and has developed by leaps and bounds in the last 20 years. The silicone glass fiber tube adopts a special "annular groove" shaped cross-section in the structural design. This kind of tube has a novel design and a reasonable structure, breaking through the "plate" traditional structure of ordinary tubes, so that the tube has sufficient pressure resistance and resistance. impact strength, but also has good flexibility.
Good flexibility: anti-distortion, good bending performance, can withstand heavy loads; acid, lubricating oil, coolant, etc., shiny surface, friction resistance.
Bearing capacity: It can withstand the heavy pressure of the foot, without breaking or deforming, can recover quickly, and has no damage itself.
Silicone glass fiber tube application field
Silicone glass fiber tubes are widely used in wiring connections in instrumentation, control cabinets, equipment manufacturing, engineering installations, trains, automobiles, subways, machine tool machinery, automation control, etc., and can be used to protect wires and cables from being cut and split And other mechanical damage, it is more suitable for protecting some corners or bent wires.
1. Automotive wiring harness field: Mainly used in automotive wiring harness assemblies, including: automotive air-conditioning pipeline sheath tubes, wiring harness silicone glass fiber tubes, wiring harness flame-retardant silicone glass fiber tubes, automotive ventilation pipes, and refrigerated transport vehicle drip pipes , Automotive wire harness tubes, automotive brake system sheath tubes, car oil and gas pipes, machine tool wire harness tubes and other automotive silicone glass fiber tubes, air-conditioning drip tubes.
2. In the field of construction engineering: widely used in the sheathed piping system of outdoor communication cables and optical cables, including inter-office relay pipes, wire pipes, feeder pipes, distribution pipes and dedicated network pipes, as well as special long-distance communication pipes. It has strong usability and is suitable for putting cables, wires and many other cables.
3. Mechanics and electronics field: It is widely used in the sheath tubes and wire tubes of various electrical, mechanical and machine tools. At the same time, the reasonable matching of silicone fiberglass tubes and various adapters can work well in the connection between mechanical assembly and machinery.
4. Household appliances: water inlet and outlet pipes of various household appliances, insulating sheath pipes, flame-retardant sheath pipes, bathroom sewer pipes, etc.
With the rapid development of new energy vehicles, silicone glass fiber tubes are more and more widely used in automotive wiring harnesses.
Selection basis: Why must the wire harness be covered with silicone fiberglass tube instead of other things. Because the silicone glass fiber tube has its unique function in protecting the wire harness, firstly it is very soft and can be bent into different angles according to the needs, which is unmatched by other materials, secondly it can withstand high temperature, fire and flame retardant, and is easy to operate ,Affordable. At the same time, the silicone fiberglass tube for automotive wiring harnesses can also be acid and alkali resistant, corrosion resistant, and oil resistant.
Type of pipe material: Silicone fiberglass tubes are generally not closed, because silicone fiberglass tubes are generally used on the main line, and the outgoing direction of the main line is inconsistent, so the silicone glass fiber tube with a break is generally selected. In addition, the choice of silicone fiberglass tubes should be based on different materials of silicone fiberglass tubes according to the temperature of the working environment.
Tube size: The size of the silicone glass fiber tube is generally selected according to the cross-sectional area of the wire harness. The cross-sectional area of the wire harness is generally 3/4 of the inner cross-sectional area of the silicone glass fiber tube. If the cross-sectional area of the wire harness is 7.5mm2, the selected silicone glass fiber tube is 10mm2.
knowledge development
According to the specific location where the open silicone fiberglass tube is installed on the car, the wrapping method of the silicone fiberglass tube is determined. There are three methods: dense wrapping, spot wrapping, and flower wrapping.
Note:
Full wrapping (tight wrapping): When wrapping, the tape overlaps by 1/2~1/3 of the tape width.
Coarse wrapping (flower wrapping): There is no overlap in the wrapping, and the wrapping gap should be within the range of 10mm-25mm.
Fixed wrapping (point wrapping): wrapping only one point or a few points in a certain section of the wire harness, and the tape is wrapped 2-3 times.
