Polyethylene (modified anhydrous phosphogypsum) double crest reinforced drainage pipe

Product Description:

Polyethylene (modified anhydrous phosphogypsum)

Polyethylene (modified anhydrous phosphogypsum) double-peak reinforced drainage pipe is made of high-density polyethylene (HDPE) resin as the main raw material, adding appropriate amount of phosphogypsum, light stabilizers, lubricants, coloring agents, etc. through the co-mingling modification and different molding processes, with the inner wall smooth and the outer wall of a new type of new lightweight pipe with closed corrugation, which is a U-shaped notch and a double-peak structure with a wave peak formed by this “U” shaped notch. The cross-section of the closed corrugation is a “U”-shaped groove, and the “U”-shaped groove constitutes the double crest structure of the crest.

The new pipe has the characteristics of light weight, good toughness, good anti-settlement performance, fast construction, long life, etc. Its excellent wall structure design, compared with other structures of the pipe, the cost is greatly reduced. Connection method innovatively adopts the slot type anti-dislodgement elastic seal ring socket connection, the connection is easy to install, the joint has good anti-settlement performance, and has been applied in the field of municipal engineering.

Execution standard

T/GZHG 023-2021 Polyethylene (Modified Anhydrous Phosphogypsum) Double Wave Reinforced Drain Pipe

Product use

    Municipal engineering road sewage and drainage pipe materials, urban sewage treatment plant network engineering, urban pipeline corridor, highway, bridge drainage engineering, sewage pipeline engineering, flood relief and drainage engineering, culverts and other fields.

Product characteristics

1、High ring stiffness: the pipe is made of modified high-density polyethylene material, the material bending modulus is high, up to more than 1250MPa.

2, good flexibility: ring flexibility can be pressed to 30% of the outer diameter (the following figure DN500 ring flexibility test), no delamination of the inner and outer walls, cracking or reverse bending. The pipe has good flexibility and excellent impact resistance.

3, excellent mechanical structure: the pipe adopts one-piece hot extrusion, the outer wave is ring corrugated structure, the inner wall is flat, no fusion joints, structural stability. Double-wall corrugated pipe buried in the ground, the soil will be embedded in the pipe valley, the pipeline to withstand the pressure load above the deformation, deformation extrusion of soil on both sides of the soil and the soil in the valley, both sides of the soil on the pipeline to produce a reaction side pressure, the side pressure to stop the deformation of the pipe support. Pipe and soil contact area is large, the formation of pipe and soil together, the stronger the pipe comprehensive compressive strength is high, excellent mechanical structure.

4, long service life: pipe material formula to add special additives, pipe performance is good, oxidation-induced time (200 ℃) can reach more than 30min. Meanwhile, the sealing ring adopts EPDM rubber, which improves the performance. Buried state, the pipe and supporting the use of sealing ring with a long service life;

5、Because the molecular structure of nano-modified HDPE material is non-polar, good chemical stability, acid and alkali corrosion resistance, the pipe can be used in a variety of harsh environments.

6, easy to install, quick construction: the use of anti-dislodgement sealing ring socket sealing ring connection, convenient, safe, stable and reliable, pipe installation is not affected by artificial, weather, environmental factors, and light weight, easy to carry, greatly reducing the labor intensity and the use of machinery, shorten the construction period, cost savings. In the case of tight schedule and poor construction conditions, its advantages.

7, good performance of anti-settlement: create the design of anti-dislodgement type joints, can cope with the more demanding geological settlement environment, can ensure that the geological settlement conditions do not fall off, do not leak, to avoid the foundation suffered from scouring, do not appear roadway subsidence accidents.
