Washover Pipes
The washover pipe offered by Dongying Lake Petroleum Technology Co., Ltd is an oilfield fishing tool designed to release a stuck section of drill‑string in the wellbore. It is manufactured from high‑strength alloy steel to API 5DP grades P110 and S135 and is supplied in nominal diameters from 3‑1/2 inches to 7 inches. Each pipe incorporates the company’s proprietary FJWP two‑step double‑shoulder thread, which provides rapid make‑up and high torsional capacity. The connections are engineered for superior torque transmission and leak resistance, meeting the clearance demands of modern wellbore fishing operations.
The material choice of P110/S135 alloy steel delivers a typical tensile strength of around 150 000 psi and a pressure rating typical of 10 000 psi at 100 °F, aligning with standard API 5DP performance. Wall thickness for these sizes usually ranges between 0.20 inches and 0.50 inches, a common industry practice for maintaining structural integrity under cyclic loading. The proprietary FJWP thread offers a double‑shoulder profile that is recognised for reducing make‑up time while sustaining torque levels required for heavy‑duty fishing tasks. Such specifications place the product firmly within the conventional parameters used by drilling contractors worldwide.
Primary users include drilling contractors, work‑over service companies and well‑intervention specialists who need reliable retrieval of stuck drill‑string components. The pipes are typically ordered in bulk consignments and shipped under FOB or CIF terms, with packaging usually in standard steel bundles protected by wooden crating. While the listing does not disclose a minimum order quantity, payment methods and exact lead times should be confirmed directly with the supplier before placing an order.

Sourcing Washover Pipes from Dongying Lake Petroleum Technology Co., Ltd - China Import Guide
Before placing an order, verify that the pipe dimensions, material grade and thread type match the requirements of your well‑intervention plan. Request the supplier’s API 5DP test reports and any third‑party inspection certificates to confirm compliance with industry standards. Clarify whether the listed sizes include any custom tolerances that may affect your fishing equipment.
Discuss logistics early, specifying the preferred Incoterm such as FOB Qingdao or CIF Shanghai, and confirm the expected lead time for production and shipment. Because the supplier’s response rate is currently 0, arrange a formal communication channel and agree on payment terms, typically a letter of credit or telegraphic transfer, before finalising the contract.
Plan for quality control by arranging a pre‑shipment inspection through an accredited third‑party agency. Ask the supplier for mill test reports, dimensional inspection sheets and torque test results for the FJWP thread. Maintaining proper documentation will streamline customs clearance and ensure the received pipes meet the performance criteria required for safe wellbore fishing.
