Dongying Lake Petroleum Technology Co., Ltd supplies Casing Pipe made from carbon steel and offered in the API 5CT grades J55, K55, N80, L80 and P110. The product can be provided in outer diameters that typically range from 4.5 inches to 20 inches, with wall‑thicknesses commonly between 0.2 and 0.75 inches. The pipe conforms to the API Spec 5CT and API Spec 5B standards, ensuring it meets the mechanical and dimensional requirements for oil, gas and water well construction.
In the industry, casing pipe of this type is usually supplied in seamless form to withstand high axial tension and internal pressure. Standard lengths are 9.5 metre sections, and thread connections are generally BTC, LTC or STC, matching the downstream equipment used in well‑bore operations. Typical pressure ratings reach up to 10,000 psi and tensile strengths exceed 70,000 psi, providing the reliability needed for demanding down‑hole environments.
Upstream oil‑and‑gas developers, water‑resource engineers and well‑service contractors commonly purchase this product for constructing well strings, protecting the borehole and facilitating fluid transport. Dongying Lake offers flexible minimum order quantities, allowing buyers to scale purchases to project size. Shipping is typically arranged on CIF terms with payment via a standard L/C, and the pipe is packaged to protect against corrosion and mechanical damage during transit.

Before confirming a purchase, verify the exact outer diameter, wall thickness and API grade to ensure the pipe matches your engineering drawings. Request the mill test report and any applicable API inspection certificates to confirm that the mechanical properties meet project requirements. It is also prudent to check that the supplier can produce the custom dimensions you need.
Logistics are generally arranged on CIF terms with payment through a documentary L/C. Although the listing does not provide a specific lead‑time, ask the supplier for an estimated production schedule and shipping timeline, and confirm the loading port in China as well as the Incoterm details.
Arrange an independent third‑party inspection based on API 5CT and API 5B procedures before shipment. Ask for the dimensional inspection certificate, visual check report and any relevant quality documentation. Having these records will help you accept the goods confidently and avoid unexpected quality issues.
