Reinforced winding tubes are also known as carat tubes. It is a kind of special-shaped structural wall pipe with smooth inner wall, spiral stiffener on the outer wall, HDPE winding reinforcing pipe made by spiral winding process, which belongs to the hose. It is made of high-density polyethylene as raw material and formed by hot melt winding.

Reinforced spiral wound tube is cooled by rolling air before hot demoulding. The pipes gradually dissipate heat and the wall thickness increases. During production, the two ends of the tube are processed into sockets, and the electric fuse is embedded in the socket ends. When connecting HDPE winding reinforcement pipe, the welding can be completed by simply connecting the power supply, and the piping system can achieve zero leakage. HDPE Connection mode of spiral reinforced pipe: socket electric fusion connection, socket rubber ring connection, throttling rubber ring connection.

Transportation and storage of reinforced-wound pipes:HDPE Spiral Hoses must not be rolled on hard and uneven ground or stone floors, In case of damage to the pipeline for short-distance transportation. When the inner diameter of the winding reinforced pipe is greater than 1000mm it should not be stacked and transported. When small-diameter pipes are transported in stacking, the winding reinforcement pipes should be stable HDPE and there should be a gap between the pipes to prevent the pipes from sliding.

When the reinforced winding pipe is stacked and transported, its height shall not exceed 2mspan style="font-family:Songti", the contact between the car and the pipe should be smooth, and it should be fixed on the transport vehicle with a flexible belt or rope to prevent rolling and collisions. HDPE inner diameter of the winding reinforced tube is greater than or equal to 1000mmWhen , a support ring should be added during transportation. If the inner diameter is larger than 2000mm you must add a support ring.

When the reinforced winding pipe is placed directly on the ground, the ground should be level, and there should be no stones and sharp objects that can easily damage the pipe, and measures should be taken to prevent the pipe from rolling. HDPE winding reinforcement tubes of different diameters are stacked on the lower side and the light ones are placed on the upper side. Both sides of the pipe should be plugged with wooden wedges or planks. Attention should be paid to the bearing capacity of the bottom pipe when pouring. The stacking height does not exceed 2.4m, and the deformation does not exceed 6%.

Maximum operating temperature of 45°C. Summers are hot. It is necessary to avoid sunlight and maintain air circulation between the pipes to prevent the temperature from rising. HDPE The winding reinforced pipe should be strictly waterproof and the pipe seat should be clean during storage. Long-term open flames are strictly prohibited near pipelines.

Reinforced winding pipes can also be divided into HDPE double-walled winding pipesHDP plastic steel winding pipe, HDPESocket double-wall spiral drain with double-wall corrugated pipe, reinforced spiral PE bellows, FRPP double-walled corrugated pipes and other large-diameter sewage pipes.
