Shenyang Expressway Tunnel Fire Protection System Electric Heating Belt Antifreeze and Insulation Project

Shenyang Hunnan Avenue Expressway Tunnel

The standard section of the Shenyang Hunnan Avenue Expressway Tunnel is 27.5 meters wide, and the widened section is 48 meters wide. It is the widest urban expressway tunnel in Northeast China. Together with the Changqing Street Expressway and the Shengli Street Expressway, it has initially formed an expressway network system, which is conducive to supporting the outward flow of urban functions, opening up the urban pattern, effectively alleviating traffic congestion in the central area, and at the same time strengthening the transportation connections between the peripheral new cities and the central area. , it is of great significance to realize the southward transfer of the city’s second ring function.

In the standard section, the width of a one-way single-hole tunnel can reach 12.25 meters, and the width of a single lane can reach 3.5 meters; while the width of a general one-way, single-hole, three-lane tunnel is about 11.5 meters, and the width of a single lane is 3.15-3.2 meters. For the decoration project in the tunnel, all the equipment selected are from well-known first-line brands at home and abroad. Anhui Huanrui undertook the design, supply, commissioning and operation of the tunnel fire pipeline electric heating cable project in this project.

Project application background

The project is located in the Northeast region, where extreme low temperatures in winter can reach -30.6°C and the average temperature is around -10°C. Therefore, it is necessary to antifreeze the water in the fire pipes in the highway tunnel that have been relatively static for a long time to prevent The fire-fighting system will be paralyzed due to freezing blockage, which may lead to safety hazards due to the inability to use it in special circumstances.

Anhui Huanrui Tunnel Fire Pipe Electric Heating System

Anhui Huanrui Tunnel Fire Pipe Electric Heating Cable System (the product used in this project is a series constant power electric heating belt). The electric heating belt is directly laid or wound and applied closely to the surface of the fire pipe to supplement the heat loss. Along its own length The range adjusts the water temperature at each control point of the pipeline system to maintain the water temperature within the required temperature range, thereby achieving the purpose of preventing pipeline freezing. The tunnel fire pipeline electric heating system consists of electric heating tape, power supply system, accessory system, control and detection system, etc. During operation, the heating system can be monitored and tested in a timely manner to facilitate users to turn on and off the system in time.

Working principle of series constant power electric heating cable

The series constant power electric heating tape is an electric heating product with a core wire heating element. That is, when current passes through a core wire with a certain resistance, the core wire emits Joule heat due to the resistance per unit length of the core wire and the current passing through. It is equal throughout the length, and the heat generated everywhere is equal. It will not cause low power at the end as the length of use increases. It is suitable for heat tracing and insulation of long-distance pipelines and is powered by one power point.

At present, the electric heat tracing project has been delivered and has been running smoothly for more than a year. The operating effect and heat tracing efficiency have received good feedback from customers. In the future, Anhui Huanrui will continue to provide customers with reliable products and professional heat tracing services, promote the application of electric heat tracing systems in more fields, and allow users to truly feel the convenience of electric heat tracing, antifreeze and insulation systems.

Are spiral wrap protector and wire winding tubes the same thing?

The spiral protective wrap and spiral winding tube are new products that replace the traditional metal guard spring, which can not only fix and bind the products inside it, but also protect it from adverse environmental factors. They are somewhat similar in performance, both have good wear resistance, corrosion resistance, etc., but they are also different.

Let's start with the most distinct material：

Taking our company's products as an example, the spiral wrap protector is generally made of modified PP material, and the wire winding tube is only made of PE material. PP and PE are thermoplastic resins made from the polymerization of organic matter, of which PP material products have the effect of temperature resistance, corrosion resistance and anti-aging, and its density is the lightest general plastic. In addition, due to the reason of high cleanliness, it has excellent performance in terms of surface stiffness and scratch resistance. The PE material products have good low temperature resistance and can resist most acid and alkali corrosion.

Then compare the two from the appearance：

PE wire protective cover is generally produced in transparent color and black, its wall thickness is relatively thin, and its body feel is soft, bending is very good. The color of the spiral protective sleeve of PP material is no transparent color, and the color it generally produces is red, yellow, black, white and blue, and other colors can also be customized. The wall thickness of the spiral protective sleeve is significantly slightly thicker than that of the winding tube, so its binding ability is more powerful, but its elasticity is not bad

Finally, from the use point of view：

The biggest advantage of the spiral protective sleeve compared with the winding tube is that the protection of the wire and other products is stronger. Therefore, it is often used in equipment with harsh or changeable environment, such as excavators, cranes, cranes and other large heavy construction machinery and equipment, it can not only prevent ultraviolet radiation to the wire, but also prevent or weaken the damage to the wire in high and low temperature, oily environment. The degree of protection of the winding tube is weaker than the former, but by virtue of its lightweight, soft, green and environmentally friendly, as well as the outstanding performance of preferential prices, it is widely used in the bondage and care of family wires and mobile phone wires, and to a certain extent, it has the effect of beautifying the environment.

What is the difference between dual wall and single wall heat shrink tube?

What is the difference between a dual wall heat shrink tube and a single wall heat shrink tube?

Single wall heat shrink tube：The waterproof sleeve made of heat-shrinkable film raw materials is used to extrude the polymer or polymer aluminum alloy to obtain the tubular intermediate product of the required specifications. The tubular product of certain specifications obtained after radiation (or organic chemistry) chemical crosslinking is heated, expanded, cooled and shaped to become a heat-shrinkable band tube.

D ual wall heat shrink tube: Basically, a layer of hot melt glue is added to the ordinary heat shrink tube. In summary, the single wall is a general heat shrink tube, and the inner cavity is not coated with hot melt adhesive. The double-wall heat shrinkable tube is characterized in that the cavity of the heat shrinkable tube is coated with a layer of hot melt adhesive.

The inner cavity of the heat shrinkable double-wall heat shrinkable tube and the glue coated mid-wall tube can be coated. Naturally, many people can use a mid-wall thermoplastic tube without a coating.

Midwall coated heat shrinkable tube Radiation crosslinked heat shrinkable midwall thermoplastic tube is generally used for insulation safety protection of medium and low voltage power engineering products and moisture protection of communication equipment. The inner cavity of the product is coated with spiral hot melt adhesive, which has excellent direct coating performance and excellent sealing effect. MWP and MWPC are uncoated and coated products respectively. The double-wall adhesive heat shrinkable tube is a semi-soft heat shrinkable tube with a hot melt adhesive in the inner layer.

The surface layer is a radiation crosslinked polyolefin, and the inner layer is a gel chamber with professional design scheme. When heated, the inner cavity melts, the surface gathers and is filled with pores or gaps after cooling, the wall thickness of the heat-shrinkable double-wall heat-shrinkable tube is symmetric and firm.
