Dongying Lake Petroleum Technology Co., Ltd supplies tubing pup joints used to adjust the length of oil‑field tubing strings. The joints are forged from carbon steel or alloy steel to API 5CT grades J55, K55, L80, N80 and P110. Available nominal sizes range from 2 3/8 in to 4 1/2 in and are provided with thread connections such as STC, LTC, BTC, EUE and NUE.
In the oil and gas sector, API 5CT grade‑L80 typically withstands a working pressure of up to 600 bar, while grade‑P110 can handle pressures above 1000 bar. Standard surface treatment includes a protective coating to resist corrosion, and the threads are protected by removable thread protectors during transport. Typical wall‑thickness tolerance for pup joints is ±0.15 mm, and the components are usually packed in bundles on wooden pallets or steel straps according to customer requirements. These specifications align with common industry practices for downhole equipment.
The pup joints are purchased by drilling contractors, oilfield service companies and EPC firms that need precise length adjustments in their tubing strings. Buyers generally request quotations based on quantity and required grade, and must confirm minimum order quantities, lead times and incoterms with the supplier. The listing shows a harbor trust tier but a zero response rate, so importers should verify communication channels and request quality management certificates before proceeding.

Importers should first request material test reports, API 5CT certification and coating inspection records to verify that the pup joints meet required specifications. Obtaining a sample set for dimensional and thread‑fit verification is also advisable before confirming a large order.
Logistics for pup joints usually involve FOB or CIF incoterms, with lead times that vary according to grade and order size. Confirm payment terms such as T/T or irrevocable LC and clarify whether the quotation will be based on metric tons or per set. Ensure that the supplier can arrange loading onto containers that accommodate the bundled pallets without damage.
During the procurement process, arrange for a third‑party inspection to check thread integrity, wall thickness and coating condition. Verify that the shipment includes a packing list, certificate of origin, API test certificates and any other customs documentation required for entry into the destination country.
