Capillary tubing and control line coil tubing from Qingdao Banghua Wire & Cable Co., Ltd are precision-engineered stainless steel tubes in grades 304 and 316L. These tubes serve instrumentation, hydraulic, and oil and gas applications, with outer diameters from 0.5mm to 25mm and wall thicknesses from 0.1mm to 2mm. They comply with ASTM A270 and ISO standards, offering corrosion resistance for demanding environments like refineries and downhole ESP systems.
The tubing is available in round, square, and rectangular profiles, with a bright annealed finish and smooth, scratch-free surfaces. Each spool undergoes pressure testing to ensure no leakage risk, and the material delivers high tensile and yield strength. Continuous lengths without butt-welded joints allow for reliable performance in chemical injection lines, hydraulic control lines, and capillary strings. The 316L grade is particularly resistant to pitting and chloride stress corrosion cracking.
Common applications include hydraulically actuated surface-controlled subsurface safety valves, chemical injection to enhance production flow, and instrumentation in oil and gas wells. The tubing is self-supporting inside production casing, facilitating chemical delivery to inhibit corrosion and dewater reservoirs. Packaging options include spools of 5000ft, 10000ft, 15000ft, or up to 33000ft in continuous lengths. Buyers typically confirm spool dimensions and joint integrity before bulk orders.

Before ordering, verify the tubing’s material grade and dimensions to ensure compatibility with your application. Confirm whether the supplier provides mill test certificates or third-party inspections for the stainless steel grades, as these documents validate material properties and compliance with ASTM or ISO standards.
Discuss logistics details, including incoterms, port of loading (likely Qingdao), and lead times for bulk orders. Clarify whether the supplier can accommodate custom spool lengths or packaging requirements, as these factors impact shipping costs and handling efficiency. Payment terms, such as TT or LC, should also be agreed upon in advance.
For quality assurance, request samples for independent testing, including tensile strength, yield strength, and corrosion resistance tests. Inspect the surface finish and joint integrity upon delivery, and ensure the tubing meets the specified standards. Documentation, such as packing lists and test reports, should accompany each shipment for traceability.
