The Flow Tube supplied by Dongying Lake Petroleum Technology co.,ltd is a wireline component used in grease‑injection control heads for oil‑field interventions. It is designed to fit over the braided wireline or slick line and sits in the stuffing box to isolate well pressure from the atmosphere. The tube’s internal diameter is slightly larger than the wireline, and the supplier states that it must be replaced regularly to maintain sealing integrity. Dongying Lake Petroleum Technology co.,ltd manufactures the tubes in China and offers them for global shipment.
Typical flow tubes are fabricated from carbon steel, with stainless‑steel variants available for corrosive environments. Standard dimensions range from 25 mm to 30 mm outer diameter, wall thickness of 2 - 3 mm, and a length of about 1.5 m, conforming to common API pressure ratings up to 10 MPa. The tubes are supplied without additional coating, although a zinc‑plated finish is a common industry option. Quality control generally follows ISO 9001 procedures, but the supplier does not list a specific certification in the product data.
The primary users are oil‑field service firms and drilling contractors that perform wireline interventions. The supplier can ship the tubes under FOB or CIF terms to ports worldwide, but exact minimum order quantities and lead times must be confirmed directly. Buyers are advised to request test certificates for pressure rating and material composition before finalising the purchase.

Before placing an order, importers should obtain the mill test report for material composition and the pressure‑test certificate to verify the tube meets the claimed 10 MPa rating. Request dimensional inspection data, especially outer‑diameter and wall‑thickness tolerances, to ensure compatibility with existing wireline equipment. Confirm whether the supplier can provide a sample or photograph of the finished tube for visual inspection.
The supplier indicates that shipments can be arranged under FOB or CIF terms to most major ports, but the exact incoterm, container size and freight cost must be agreed in advance. Because the response rate shown is 0 %, buyers should establish a clear communication channel and obtain a written lead‑time estimate before confirming the order. Clarify the preferred payment method, such as a letter of credit, and whether a deposit is required.
Importers are advised to organise a third‑party inspection at the factory or at the loading port, focusing on material certification, dimensional accuracy and the integrity of the thread ends. Request a copy of the inspection report and any relevant ISO or API compliance documents. Retaining these records will facilitate customs clearance and future performance monitoring.
