ASTM A312 TP304L Coil Tubing
ARK Steel Tube Company supplies ASTM A312 TP304L seamless stainless steel coil tubing from Taizhou, Zhejiang, China, with an outer diameter range of 3.2 mm to 25.4 mm and wall thickness from 0.2 mm to 2.5 mm. The 18% chromium, 8% nickel composition in 304L grade delivers the corrosion resistance and elevated-temperature performance that chemical processing and oil and gas applications demand. The tubing is available in straight lengths or coiled form, with TP304, TP304L, TP316, and TP316L grades offered alongside TP321 and TP247H options.
The TP304L low-c conferring reduced sensitisation risk during welding, a factor that matters in heat exchanger circuits and fluid transfer lines where post-weld heat treatment is impractical. Coil form packaging allows continuous installation without intermediate joints, reducing leak paths in pressure control and gauge systems. Standard delivery conditions include annealed and pickled (AP), bright annealed (BA), and mechanically polished (MP) finishes, each suited to different cleanliness and surface-roughness requirements in aerospace and automotive applications.
Buyers in the automotive, aerospace, electrical, and industrial sectors use this tubing for engine and transmission fluid lines, fire suppression systems, satellite guidance hardware, and automation controls. The small-diameter coil format is particularly valued where space constraints or routing complexity make rigid straight lengths uneconomical. ARK Steel Tube Company has a harbor trust tier and zero recorded response rate, so buyers should confirm current stock, minimum order quantities, and lead times directly before committing to an order.
| Material Grade | TP304L / 18% Cr, 8% Ni (austenitic stainless steel) |
| Standards Compliance | ASTM A312 (seamless austenitic stainless steel pipe) |
| Outer Diameter (OD) | 3.2 mm to 25.4 mm |
| Wall Thickness (WT) | 0.2 mm to 2.5 mm |
| Length Format | Straight length or coil (typical coil weights vary by diameter; confirm with supplier) |
| Additional Grades Available | TP304, TP316, TP316L, TP321, TP247H (standard alternatives for this product category) |
| Carbon Content | ≤ 0.035% typical for 304L grade, reducing carbide precipitation during welding |
| Delivery Condition | AP (Annealed and Pickled), BA (Bright Annealed), MP (Mechanically Polished) |
| Corrosion Resistance | Suitable for chemical processing, oil and gas, and marine environments (typical for 304L in chloride-free service) |
| Maximum Service Temperature | Approximately 425 °C continuous (typical for 304L austenitic stainless steel; confirm exact limits with supplier) |
ARK Steel Tube Company operates from E802, Xintai Square Building, Jiaojiang District, Taizhou, Zhejiang Province, China. The supplier holds a harbor trust tier, which indicates a baseline verification level on the platform, though the response rate is recorded at 0.00% with an average response time of zero hours. This suggests either a new listing, limited engagement history, or data capture issues that buyers should factor into their due diligence.
The company's product focus is narrow and well-defined: small-diameter seamless stainless steel coil tubing in multiple austenitic grades, with ASTM A312 compliance as the central quality claim. The listing does not state annual output, factory size, in-house testing capabilities, or export certifications such as ISO 9001 or PED. Buyers should request documentation of mill test certificates, third-party inspection reports, and any country-specific approvals needed for their end market before placing an order.
This ASTM A312 TP304L seamless stainless steel coil tubing is widely used in chemical processing, oil and gas, and heat exchanger applications where corrosion resistance and high-pressure performance are critical. Supplied in small diameters in convenient coil form, it meets ASTM A312 standards for seamless austenitic stainless steel piping. Available in TP304, TP304L, TP316, and TP316L grades, this coil tubing is suitable for both domestic distribution and international export trade.

Sourcing ASTM A312 TP304L Coil Tubing from ARK Steel Tube Company - China Import Guide
Before ordering ASTM A312 TP304L coil tubing from ARK Steel Tube Company, verify that their mill test certificates include chemical composition, mechanical properties, and hydrostatic test results traceable to the heat number. Confirm the actual carbon content is at or below 0.035% for your welding procedure, and request a dimensional inspection report for your specific OD and wall thickness combination. Given the zero response rate, initiate contact well in advance to assess communication reliability and request sample coils for independent testing before committing to volume orders.
Logistics from Taizhou, Zhejiang typically ship through Ningbo or Shanghai port. Confirm with ARK Steel Tube Company which Incoterms they offer (FOB, CIF, or DAP are common for Chinese tubing exports), whether they handle export customs clearance, and what their standard lead time is from order confirmation to bill of lading. Payment terms for first-time buyers often require 30% deposit with 70% against documents, though this must be negotiated directly. Standard ocean freight to Europe is 28 to 35 days, and to North American west coast 14 to 21 days, excluding customs clearance.
Quality assurance should include third-party inspection at the mill for dimensional accuracy, surface finish verification, and eddy current testing for seam integrity. Specify that material must be free from lamination, pitting, or scale defects that could affect pressure rating. Request packing lists, certificates of origin, and material test reports in English for customs and engineering review. For aerospace or automotive applications, ask whether ARK Steel Tube Company has AS9100 or IATF 16949 certification, or whether their process controls meet your customer's supplier quality requirements.
