Detailed introduction

Polyethylene pipe for water supply

Transportation and storage:

(1) Pipes shall not be scratched, thrown, severely impacted, exposed to sunshine, rain, oil and chemical contamination when transported.

(2) Pipes are stored in well-ventilated, flat-ground car rooms, and should be stacked outdoors with shelters to avoid sun exposure and rain.

(3) Pipe stacking height shall not exceed 1.5 meters.

Product Description:

Polyethylene pipeline system has a long history and has been widely used. Using special polyethylene resin as raw material and plastic extruder as one-time mouldable pipe, injection machine as one-time mouldable pipe fittings, and special equipment as piping system through hot-melt and electric-hot-melt connection, it is an ideal material for urban water supply network, irrigation diversion project, garbage treatment plant, sewage collection pipeline project and agricultural sprinkler irrigation project. Material.

Product performance:

(1) Long service life

Under rated temperature and pressure conditions, PE pipes can be used safely for more than 50 years.

(2) Excellent corrosion resistance

Except for a few strong oxidants, it can resist the erosion of various chemical media, and has no electrochemical corrosion.

(3) Excellent wear resistance

When conveying ore mortar, the wear resistance of PE pipe is more than 4 times that of steel pipe.

(4) Good hygienic performance

PE pipe processing does not add heavy metal salt stabilizer, the material is non-toxic green building materials, no scaling layer, no bacteria, better solve the secondary pollution of urban drinking water.

(5) Better impact resistance

PE pipe has good toughness, high impact strength, and heavy objects directly press through the pipeline, which will not lead to pipeline rupture and will not be affected by foundation settlement.

(6) Reliable connection performance

The strength of PE pipe hot-melt or electric-melt interface is higher than that of the pipe body, and the joint will not be broken due to soil movement or active load.

(7) Good construction performance

The pipeline is light, the welding process is simple, the construction is convenient, and the comprehensive cost of the project is low.

Pipe standards:

The company's PE water supply pipe materials in accordance with the national standard GB/T 13663-2018 "Water supply polyethylene (PE) pipe" requirements of production inspection.

Tube color:

The PE water supply pipe produced by our company is black and blue strip, which can also be decided by both suppliers and consumers through consultation.

Connection method:

- socket hot melt connection

The exterior surface of the tube end and the interface surface are heated to the melting temperature of the material at the same time. After checking the shape of the melting port, the melting pipe end is inserted into the socket and fixed until the interface is cooled. This connection is suitable for pipes with diameter less than 125 mm.

Thermal docking

The two vertical ends of the pipe shaft will be contacted with the hot plate, so that the two ends of the pipe can reach the melting temperature, then the quantity end face will be pressed and connected, and a certain pressure will be applied in a predetermined time, and then the cooling interface will be cooled. This kind of connection is suitable for the connection of pipes and fittings with the same diameter.

Electrofusion welding

After the pipe fitting is socketed, the original part is heated by a set electric current, and the connection part of the pipe and the pipe fitting is heated, melted and bonded. Connection is completed after cooling.

Execution Standard: The product standard meets the requirements of GB/T 13663.2-2018 "Polyethylene Pipe for Water Supply".

Use precautions:

Pipes and fittings should be stored in a well-ventilated warehouse or simple shed. They should not be stored in the open air to prevent direct sunlight, pay attention to fire safety, and should not be less than 1 meter away from the heat source.

Pipes should be stacked horizontally on a flat floor, bending pipes should be avoided, stacking height should not exceed 1.5 meters, pipes should be stacked layer by layer, not too high.

When distributing pipes and fittings, they should be handled carefully and lightly to avoid oil pollution and severe impact, and to touch and throw, fall, roll and drag sharp objects.

The pipe and fittings should not be hammered with hard objects during construction, especially at low temperatures, the pipe must be cut vertically and axially, and the incision must be kept clean and smooth.

Hot-melt connections should be made in strict accordance with the required melt-drawing depth.

Hot-melt joints shall be made in strict accordance with the stipulated welding time.

The maximum deviation angle of pipes and fittings shall not exceed 5 degrees in hot-melt connection.

When bending the pipe, the bending radius should not be less than 8 times the diameter of the pipe. It is strictly forbidden to use open fire to heat the bending.

Metal threads are designed with "V" threads, and can be sealed with hemp or raw material tapes when connecting. Do not tighten them too tightly.

Elbows must be used when two pipes overlap.

Polyethylene water supply pipes should be avoided as climbing, suspension, etc.

The location and direction of the buried tube should be marked after the buried tube is closed.

Strictly prohibit impacting on pipes or nailing sharp objects such as metal nails.
