Crankshaft
Jinan Tianwei Innovation Oilfield Equipment Enterprise manufactures forged crankshafts from chromium‑molybdenum alloy steel 4140/4340, specifically designed for Emsco triplex mud pumps ranging from the F‑500 to the F‑1600 series. The parts are produced to meet API specifications and are intended for oilfield drilling rigs where high pressure and temperature are routine. Each shaft is supplied with the possibility of custom heat treatment and is packaged for secure transport to offshore sites.
In oil‑field applications, alloy steel 4140 is favoured for its combination of tensile strength and toughness; typical heat treatment involves vacuum carburising followed by tempering to reach a Rockwell C hardness of 48‑52. Dimensional tolerances are generally held within ±0.04 mm on critical journals, and surface finishes are milled to a Ra of 1.2 µm to reduce wear in high‑load gear trains. These industry norms support torque capacities up to 3500 Nm for the larger pump models.
The crankshafts serve equipment manufacturers, drilling contractors, and maintenance workshops that require OEM‑grade replacements for Emsco, National Oilwell, and Gardner Denver pump lines. Trade conditions usually include FOB or CIF from the Shandong port, with payment accepted via L/C or T/T after verification of product compliance. Prospective buyers should request the API compliance certificate and any third‑party test data before finalising the purchase.

Sourcing Crankshaft from Jinan Tianwei Innovation Oilfield Equipment Enterprise - China Import Guide
When evaluating this supplier, verify the exact alloy grade, heat‑treatment records, and compliance with API Specification 7‑1. Request a detailed engineering drawing that shows journal diameters, keyway dimensions, and surface‑finish specifications to ensure the part fits the intended mud pump model.
Typical logistics involve FOB from the nearest Shandong port, with CIF options negotiable for door‑to‑door delivery. Confirm the expected lead time, which can be affected by heat‑treatment cycles and any required custom machining, and agree on payment terms such as a documentary L/C or T/T that align with your procurement policy.
Quality assurance should include a pre‑shipment inspection or third‑party audit, especially given the high‑stress nature of oilfield equipment. Arrange for a sample test report covering hardness, dimensional checks, and API compliance, and consider an on‑site verification if the order volume justifies the additional oversight.
