Air Operated Elevators
Sourcing Air Operated Elevators from Dongying Lake Petroleum Technology Co., Ltd - China Import Guide
Before placing an order with Dongying Lake Petroleum Technology Co., Ltd, verify the supplier's current API monogram license status for SPEC 8A and SPEC 8C through the official API licensee directory, as the listing references these standards but does not confirm active licensure. Confirm the specific elevator size, load rating, and bore diameter match your drill string configuration. Request material test certificates, load test reports, and non-destructive examination records for the exact serial numbers to be supplied. Validate that the supplier's quality system is current and that traceability records are maintained from material certification through final inspection.
Logistics from Dongying, Shandong Province typically ship through Qingdao or Tianjin port for sea freight. Incoterms should be negotiated explicitly; the listing does not specify whether pricing includes export packing, inland transport, or port handling. Confirm lead time from order confirmation to ready-for-shipment status, as no standard lead time is stated. Payment terms common for first transactions with Chinese petroleum equipment suppliers include 30 percent advance with balance against shipping documents, though letter of credit terms may be negotiable for larger orders. Request the supplier's standard packing specification (typically wooden cases or steel frames for API hoisting equipment) and whether export crating incurs additional cost.
Upon receipt, conduct dimensional inspection against API tolerances for bore diameter, latch engagement, and elevator body symmetry. Perform magnetic particle inspection on load-bearing surfaces if not already certified. Test pneumatic actuation at rated operating pressure to verify smooth operation of the remote open/close function, checking for air leaks and response time. Calibrate the test setup to the supplier's specified air pressure range. Retain all documentation for API compliance verification and end-user audit requirements.
