Import Corrugated Polyethylene Plastic Pipe — Buy in wholesale FOB from Supplier in China

The Corrugated Polyethylene Plastic Pipe offered by Chaoran Plastic Co., Ltd. is a double‑wall, perforated drainage pipe manufactured from high density polyethylene (HDPE) in accordance with GB/T 19472.1‑2004. The product line covers nominal inside diameters of 225 mm, 300 mm, 400 mm, 500 mm, 600 mm and 800 mm, with corresponding outside diameters ranging from 260 mm to 970 mm and bellmouth depths between 152 mm and 260 mm. Each size is supplied with a bellmouth that widens the inlet, facilitating flow entry and reducing blockage risk. The pipe conforms to the listed Chinese standard and is presented as suitable for a range of civil and industrial drainage applications.

Typical HDPE pipe for drainage is produced with a wall thickness that yields a nominal pressure rating of about 0.6 MPa and a roughness coefficient of 0.009, providing low hydraulic resistance. The inner surface finish is smooth, which, together with the corrugated profile, gives a hydraulic roughness that improves flow efficiency compared with smooth‑wall alternatives. Standard temperature resistance for HDPE of this grade is - 40 °C to 60 °C, making the pipe suitable for most underground and surface drainage environments. The material also offers excellent resistance to acids, alkalis and most chemicals encountered in municipal or industrial settings.

Primary users include municipal engineering firms, water‑treatment plants, oil‑field operators and construction companies that require durable, low‑cost drainage solutions. Chaoran Plastic Co., Ltd. states that the pipe is lightweight, easy to handle and can be installed rapidly using simple connections, which reduces overall project labour costs. The supplier mentions flexible shipping options, but buyers should confirm the incoterm, MOQ and any required certifications before finalising a purchase. Payment conditions and lead‑time details are negotiated per order, with the supplier prepared to supply test reports upon request.

Chaoran Plastic Co., Ltd. is located at No. 7 Building Guoda International Trading Center, Dingtao Town, Shandong Province, 274100, China. The supplier is listed with a harbour‑tier verification and an imported tier label, indicating that the company is recognised for cross‑border trade; however, the response rate is recorded as zero, so buyers should allow extra time for communication.

The company’s catalogue focuses on HDPE drainage solutions, emphasising lightweight construction, chemical resistance and low hydraulic loss. The source description highlights that the pipe is suitable for municipal, chemical, oil‑field, thermal‑power, metallurgical and highway projects, but no further corporate background, production capacity or client list is provided in the data.
