Dongying Lake Petroleum Technology Co., Ltd supplies blind flanges that act as solid end caps for pipelines. Their catalogue spans nominal bore sizes from 15 NB (½ in) up to 1500 NB (60 in). The flanges are produced from carbon steel meeting ASTM A105 and from stainless steel grades 304 and 316. All dimensions are engineered to comply with ASME B16.5 and ANSI B16.5 standards, covering pressure classes from 150 psi up to 2500 psi. The items are delivered as single units ready for bolting onto the pipe line.
Typical surface treatments include a mill finish or a phosphate coating for corrosion resistance in harsh environments. Temperature capability for carbon steel versions is generally - 20 °C to 400 °C, while stainless steel can endure up to 600 °C. Bolt hole configurations range from four to twenty‑four, with bolt circle diameters that follow the ASME tables for each size. Flange thickness and hub dimensions are standardised according to the selected pressure class. Standard packaging involves sturdy wooden pallets or reinforced crates to safeguard the heavy discs during sea freight.
End users such as petrochemical plants, power stations and water‑treatment facilities rely on these flanges for safe shutdown and maintenance operations. The supplier mentions FOB and CIF shipping options and accepts L/C payment, but exact MOQ, lead time and payment schedule should be verified directly with Dongying Lake Petroleum Technology Co., Ltd.

When ordering blind flanges from Dongying Lake Petroleum Technology Co., Ltd, first confirm that the nominal bore, material grade and pressure class correspond to your project specifications. Request the mill test report and material certification for the chosen steel or stainless grade, and obtain a dimensional drawing that shows bolt‑hole layout. Verifying these documents before production reduces the risk of mismatched components.
Discuss the shipping terms with the supplier, specifying whether you prefer FOB or CIF and identifying the Chinese port of loading. Because lead times can vary with size and class, ask for a concrete schedule based on your order volume. Payment is usually arranged by irrevocable L/C; ensure that any advance payment or documentary requirements are clearly defined in the contract.
Plan a third‑party inspection either at the factory or upon arrival to validate compliance with ASME B16.5 and the material certificates. Obtain a final inspection report, dimensional verification sheet and a detailed packing list before the cargo is released. Maintaining these records will aid customs clearance and provide traceability for future quality audits.
