Import Casing Pipes — Buy in Bulk from Supplier in China

Dongying Haixin Petroleum Equipment Co., Ltd supplies carbon‑steel casing pipes with outside diameters from 4" to 20" designed for oil and gas drilling, structural foundations and underground water supply systems. The pipes are produced from high‑grade carbon steel and are engineered to withstand high tensile loads and corrosion in demanding environments. The product range includes multiple wall‑thickness options to match the selected diameter, providing flexibility for varied project specifications.

Typical carbon‑steel grades used for these pipes exhibit tensile strengths of 70,000 psi to 100,000 psi, with yield strengths around 55,000 psi, values that align with industry standards for heavy‑duty casing. Wall thicknesses generally follow standard schedules, ranging from 0.125" for smaller diameters up to 0.500" for larger sizes, with dimensional tolerances defined by API 5CT. Protective coating is applied as a standard measure to improve corrosion resistance, and the pipes are fabricated to meet common API and ISO quality benchmarks.

The primary customers are drilling contractors, construction firms and municipal water authorities that require durable tubular solutions. The supplier notes flexible order quantities and offers shipping under FOB or CIF terms, though exact conditions must be clarified directly. Importers should request the mill test certificate, API compliance documentation and any third‑party inspection reports before confirming the purchase. Payment methods and lead‑time estimates are negotiated on a case‑by‑case basis.
