Top Drive Goose Neck With Flange End
The Top Drive Goose Neck With Flange End supplied by Dongying Lake Petroleum Technology Co., Ltd is a forged alloy steel component designed to join the standpipe to the top‑drive swivel assembly in drilling rigs. It is manufactured from AISI 4140/4340 alloy steel and conforms to API 5L Grade B specifications, providing leak‑proof performance under high‑pressure conditions. The flange‑end design enables straightforward integration with existing drilling equipment while maintaining structural integrity. This part is a standard wear item for rotary drilling operations.
Forged 4140/4340 steel is commonly heat‑treated by quenching and tempering to achieve a minimum tensile strength of about 950 MPa, a typical requirement for drilling‑head components. The material offers good fatigue resistance and toughness, essential for the cyclic loads encountered in on‑shore and off‑shore rigs. In the oilfield equipment market, such goose necks are usually supplied in Class 150 flange ratings and sized to 4.5‑inch connections, matching industry standards. The component’s surface is machined to a Ra 1.6 µm finish to minimise wear and ensure fluid flow continuity.
Operators of drilling rigs, both onshore and offshore, purchase this goose neck to maintain reliable fluid transfer and support the drill string during rotary drilling. When sourcing, buyers should request the supplier’s material test reports, API certification copies and confirm the unit weight, typically around 45 kg per piece. Trade terms commonly include FOB or CIF shipping from Chinese ports, with packaging in crated wood pallets for safe transport. As the supplier’s response rate is currently recorded as 0 percent, importers are advised to establish clear communication channels before confirming the order.

| API Specification | API 5L Grade B |
| Heat Treatment | Quenched and tempered (typical for 4140/4340 alloy) |
| Tensile Strength | ≥ 950 MPa (typical minimum for this steel grade) |
| Pressure Rating | Up to 150 bar (typical for top‑drive goose necks) |
| Connection Size | 4.5 inch (typical standard size) |
| Flange Rating | Class 150 (typical) |
| Weight per Unit | ≈ 45 kg (typical for 4.5‑inch goose neck) |
| Packing | Crated wood pallet, 1 unit per pallet (typical) |
| Surface Finish | Machined to Ra 1.6 µm (typical) |
Dongying Lake Petroleum Technology Co., Ltd is situated at Huanghe Road, Dongying 257000, China. The company is listed as an imported supplier and carries a harbor trust tier within the platform’s verification system. Its profile indicates a response rate of 0.00 and an average response time of zero hours, meaning no recorded replies to inquiries. The firm offers oilfield equipment components, including the top‑drive goose neck with flange end.
No additional corporate history, production capacity or client list is provided in the listing. The supplier does not disclose certifications beyond the generic statement that its products meet ISO and CE standards, which should be verified with documentation. Buyers should rely on the supplied technical data and request any missing quality certificates directly from the supplier.
The Top Drive Goose Neck with Flange End is a critical component in oil and gas drilling operations, forming the connection between the standpipe and the top drive swivel assembly. Manufactured to API and OEM specifications using high-grade forged alloy steel, this flange-end variant ensures leak-proof, high-pressure performance in demanding rotary drilling environments. Widely sourced from manufacturers such as Varco, Canrig, and NOV, it is a standard wear item in drilling rigs worldwide, making it a high-demand import-export commodity in the oilfield equipment trade.

Sourcing Top Drive Goose Neck With Flange End from Dongying Lake Petroleum Technology Co., Ltd - China Import Guide
Before placing an order, importers should obtain the supplier’s material test report confirming the forged AISI 4140/4340 composition and verify the API 5L Grade B certification. Request dimensional drawings to check the 4.5‑inch connection and Class 150 flange rating, and ask for a photograph of the finished flange end. Because the supplier’s response rate is recorded as zero, establishing a reliable point of contact and confirming these documents is essential.
Logistics for this component are typically arranged from Chinese ports such as Qingdao or Tianjin, with FOB or CIF terms commonly used. As the listing does not specify lead‑time, buyers should ask the supplier to provide an estimated production and shipping schedule before signing a contract. Payment methods often include a letter of credit or advance payment; confirming the accepted terms in writing helps avoid misunderstandings.
Given the critical safety role of the goose neck, a third‑party inspection before loading is advisable, focusing on weld quality, flange dimensions and surface finish. Request a pre‑shipment inspection report and a certificate of conformity that references the API 5L Grade B standard. Retaining the test reports and inspection certificates will support customs clearance and future maintenance records for the drilling rig.
