Dongying Lake Petroleum Technology co.,ltd supplies Glass Reinforced Epoxy (GRE) pipe that is manufactured by filament winding of epoxy resin with high‑strength E‑glass roving. The product is certified to API 15HR and API 15LR standards and is presented for use in upstream oil and gas operations, including offshore platforms, subsea flowlines and high‑pressure hydrocarbon transfer. The catalogue lists a diameter range of 43.5 mm to 1638 mm (1‑inch to 40‑inch) and a rated pressure range from 3.45 MPa to 34.5 MPa, with a maximum operating temperature of 110 °C.
In the pipe industry, GRE material typically provides a tensile strength of around 70 MPa and a density near 1.9 g cm‑3, which results in a lightweight alternative to steel pipelines while maintaining comparable strength. Standard wall‑thickness ratios for GRE pipe fall within 0.04‑0.08 of the nominal diameter, offering sufficient rigidity for high‑pressure service. Typical temperature resistance extends to about 120 °C, and the smooth internal surface minimises friction loss and prevents scale build‑up, a common advantage cited for GRE pipelines.
Project engineers and procurement departments select GRE pipe for wastewater transmission, high‑pressure petroleum delivery, saline water transport and CO₂/H₂S handling because of its corrosion resistance and ease of installation. Buyers should request the specific API certification documents, dimensional drawings and pressure‑class data before confirming quantities. As the listing does not disclose pricing, MOQ, lead‑time or incoterms, these trade terms need to be negotiated directly with the supplier.

Dongying Lake Petroleum Technology co.,ltd is based on the 15th floor of Huatai Center in Dongying City, Shandong Province, China (postal code 257000). The company is listed as an imported‑tier supplier with a harbour‑level trust tier; its response statistics show a 0.00% response rate and no average response time recorded, indicating limited communication activity at present.
The supplier’s catalogue includes GRE pipe products that meet API 15HR/15LR specifications and are promoted for applications such as wastewater treatment pipelines, high‑pressure petroleum and natural‑gas delivery, and connections to storage tanks or fire‑hose systems. The description stresses lightweight construction, excellent mechanical properties and resistance to scale or secondary contamination.
GRE (Glass Reinforced Epoxy) pipes are high-performance composite piping solutions widely deployed in oil and gas upstream operations, including offshore platforms, subsea flowlines, and refined hydrocarbon transfer. Certified to API 15HR and API 15LR standards, these pipes offer exceptional corrosion resistance in harsh chemical environments while maintaining structural integrity at pressures up to 34.5 MPa. Available in diameters from 43.5 mm to 1638 mm (1" to 40"), GRE pipe is the preferred choice for projects prioritizing lightweight durability and long-term integrity in demanding industrial applications.

Importers should first verify the API 15HR/15LR certificates and request material test reports that confirm tensile strength, density and temperature resistance. Detailed engineering drawings showing wall‑thickness, dimensions and pressure class are essential before finalising any purchase agreement.
Because the listing does not specify incoterms, packaging or lead‑time, buyers need to clarify whether the pipe will be shipped in bulk reels, bundled sections or individual coils, and which freight terms (FOB, CIF, etc.) apply. Confirming the port of loading in China and any required pre‑shipment inspections will help avoid unexpected delays.
Standard quality procedures include visual inspection for fibre waviness, dimensional checks against the supplied drawings, and non‑destructive testing for resin cure quality. Importers are advised to arrange third‑party inspection and to obtain a Certificate of Conformity, material safety data sheet and any additional test certificates before the goods leave the supplier’s facility.
