Product Description

PP telescopic corrugated tube with steel

Constitute: Corrugated vacuum hose is extruded by hard bones and muscles frame and environmental protection material (polyether ester) hard bar.

Characteristics: Corrugated vacuum hose extrusion skeleton is uniform and good toughness, the surface outside pipe is bright, clean and level off, without a scratch, crack, bubble, uneven, Ge nest, lack of glue, delaminating, double skin, NingJin, efflorescence, lack of material defects etc. affect the appearance and use of performance.

Applications: Widely applied in cable casing,construction drainage,agricultual drainage,irrigation,chemical industry,medicine and ventilation ducts etc.

Mark: OEM products are welcome.
