HDPE underground pipe jacking


Polyethylene (PE) pipe plays an important role in underground pipe jacking due to its excellent mechanical properties, electrical properties, impact resistance and environmental protection properties, and its use is increasing. The HDPE underground jacking pipe produced by Liangcheng is produced by the advanced polyethylene pipe extrusion production line. Because of its unique screen basket head design, advanced barrier screw and IKV forced extrusion system, etc., it ensures the full melting and plasticization of raw materials, and ensures that the polyethylene pipe has excellent fast and slow cracking resistance in use.

COD corrugated bundle pipe


COD stands for Corrugated Optical Duct, which is a whole composed of multiple internal cable pipes and outer pipes. COD and traditional general PE pipes assemble the inner pipes (3 to 5) that have been manufactured into the outer pipes through the reproduction process.

HDPE micro tube bundle


Microtube is a kind of soft plastic tube with small size and light weight. Its maximum outer diameter should not be greater than 16mm. Microtube must be round.

Seven-hole plum blossom tube


HDPE seven-hole plum blossom pipe is a kind of cable sheath pipe with HDPE (high density polyethylene) as raw material, which is produced by extrusion molding at one time, and the single hole walls intersect and are tightly fused. The product has the characteristics of waterproof, moisture-proof, anti-aging, long service life and good weather resistance. At the same time, because it is a one-time molded integrated porous casing, in terms of use and construction, the number of embedded holes is increased, the construction speed is improved, and the material and construction costs of the engineering unit are greatly reduced.
