Construction & real estate›💡Electronic & Electrical›🍎Food & Beverages›🛋️Home furnishing & supplies›⚗️Industrial goods & chemical›🪨Minerals & metals›📦Miscellaneous›Dongying Lake Petroleum Technology co.,ltd offers a foam pig valve designed for high‑pressure pipeline pigging applications. The valve conforms to API 6D and carries the company’s patent number ZL 97 2 39827.9. It is intended to launch and receive foam pigs in oil, natural‑gas, chemical and water pipelines. The design targets the removal of deposits, protection of delivery volume and extension of pipeline service life. The valve features a fast‑opening door equipped with an elastic automatic wedge‑caulking steel belt, a horseshoe double‑eccentric centre lock and a pressure‑relief lock, allowing flexible operation on large‑diameter pipelines. Body construction uses carbon steel that meets API 5L specifications, a standard material for pipeline service. Typical pressure ratings for API 6D pig valves reach up to 30 MPa and size ranges from DN 50 to DN 2000, which aligns with industry practice. Such mechanisms are widely adopted in oil‑gas gathering, offshore platforms and chemical storage facilities. End users include pipeline operators, EPC contractors and maintenance firms that require reliable pigging equipment. The supplier ships the valves in wooden cases, carton cases or containers according to buyer preference, but exact MOQ, price and lead time must be confirmed directly with the company. Buyers should request detailed drawings, material certificates and test reports before finalising a purchase.

Before placing an order, verify that the valve conforms to API 6D and request the material test certificate for the carbon‑steel body. Ask for detailed engineering drawings, the patented mechanism diagram and any third‑party test reports that demonstrate pressure‑holding performance at the intended operating temperature. Confirm that the supplied dimensions match the DN size you need and that the locking system is compatible with your pipeline configuration.
Logistics should be clarified with the supplier, including the preferred Incoterm, typical lead time and payment conditions, as these details are not disclosed in the listing. Discuss the most suitable packaging - wooden case, carton or container - and ensure that the chosen option protects the valve during transport. Request a freight quotation and verify whether the supplier can arrange customs documentation for export from China.
Upon receipt, arrange a third‑party inspection to confirm pressure rating, material composition and the integrity of the fast‑opening door mechanism. Request a pressure‑test certificate and a certificate of conformity to API 6D standards. Ensure that the final documentation package includes the material test report, the patent reference and any relevant quality‑assurance records before accepting the shipment.
