Type Dd Elevators
The Type Dd Elevator is a centre‑latch lifting device designed for oil‑field tubular handling. It is fabricated from high‑strength alloy steel and carbon steel grades AISI 4140/4340, meeting API Spec 8C requirements. Load capacity ranges from 150 tonnes to 350 tonnes and it accommodates pipe and tubing diameters from 2 3⁄8 in to 5 1⁄2 in. The square‑shoulder design provides a robust interface for drill pipe, drill collars, casing and tubing.
The alloy composition delivers a tensile strength of roughly 1100 MPa, a typical figure for AISI 4140/4340 used in heavy‑duty hoisting equipment. Standard machining tolerances for the bore and shoulder are ±0.005 in, ensuring repeatable fit on standard drill‑pipe connections. Heat‑treatment and quench‑tempering are standard processes to improve fatigue resistance. Such specifications align with common industry practice for drilling‑service elevators.
These elevators are purchased by drilling contractors, oil‑field service firms and equipment distributors engaged in offshore or on‑shore exploration projects. Buyers usually request bulk shipments packed in wooden crates with palletised handling, and they negotiate Incoterms such as FOB or CIF based on project logistics. Minimum order quantities are not disclosed publicly; prospective purchasers should confirm MOQ directly with the supplier. Payment terms are typically arranged via irrevocable Letter of Credit, subject to the supplier’s credit assessment.

Sourcing Type Dd Elevators from Jiangsu Rudong Lianfeng Petroleum Machinery Co., Ltd. - China Import Guide
Before placing an order, importers should verify that the elevators conform to API Spec 8C and request the material test report together with the heat‑treatment certificate. It is essential to confirm that the exact bore dimensions, load rating and square‑shoulder geometry match the intended drilling string, and to obtain a detailed dimensional drawing to prevent mismatches during rig‑up. Additionally, buyers should ask for evidence of the supplier’s quality management procedures or any third‑party inspection records.
Logistics for these heavy units typically involve containerised shipment on a 20‑ft or 40‑ft container, secured within wooden crates. The supplier does not publish lead‑time, so buyers must confirm the production schedule and expected dispatch date. Common Incoterms used are FOB Rudong Port or CIF destination, and payment is usually arranged via irrevocable Letter of Credit, subject to the supplier’s credit assessment.
Importers are advised to arrange a pre‑shipment inspection by an accredited third‑party agency to verify dimensional tolerances, surface finish and load‑test results. Upon arrival, a non‑destructive test such as ultrasonic or magnetic particle inspection should be performed to detect any hidden defects. All certificates, including material test, heat‑treatment, API compliance and inspection reports, must be retained for customs clearance and future warranty claims.
