Import C-Chd Spiders — Buy in Bulk from Supplier in China

The C‑CHD Spider series offered by Jiangsu Rudong Lianfeng Petroleum Machinery Co., Ltd. are pneumatic devices used for handling drill pipe and tubing during oil‑well repair operations. Two models are described: type C, which accommodates pipe diameters from 1.315 in to 5 ½ in and carries a rated load of 80 tonnes, and type CHD, which covers the same size range but is rated for 120 tonnes. Both models are designed for pneumatic actuation and are built to operate in the demanding environment of well‑service rigs.

Typical construction for this class of spider involves forged steel bodies with heat‑treated surfaces to resist wear and corrosion. Industry practice calls for a pressure rating of at least 0.7 MPa for the pneumatic circuit and a safety factor of 1.5 on the load capacity. The standard material grade is usually AISI 4140 or equivalent, providing high tensile strength and good fatigue performance. These spiders are frequently supplied with standard 3/4 in NPT pneumatic fittings, which are compatible with most rig air‑supply lines.

Primary customers are drilling contractors, well‑service companies and oil‑field equipment rental firms that need reliable pipe‑handling equipment for workover and intervention jobs. The supplier lists the spiders as part of a broader range of petroleum‑machinery products, but does not disclose minimum order quantities, pricing tiers, delivery terms or lead‑time estimates. Prospective buyers should therefore request a detailed quotation and confirm all trade terms directly with Jiangsu Rudong Lianfeng Petroleum Machinery Co., Ltd.

Jiangsu Rudong Lianfeng Petroleum Machinery Co., Ltd. is located in the Economic Development Zone of Rudong County, Jiangsu Province, China, with the address Huaihe Road, Rudong 226400. The company appears in the platform’s harbour‑tier verification, but its response rate is recorded as 0 % and the average response time is 0 hours, indicating limited communication data on the platform.

The supplier’s catalogue focuses on petroleum‑machinery equipment, and the C‑CHD Spider listing confirms capability in high‑load pneumatic handling devices. No additional corporate details such as founding year, employee count or revenue are provided, so buyers should rely on product specifications and, if possible, on‑site assessments to gauge manufacturing capacity.
