Stainless steel tube suppliers with export experience to the US and EU

Stainless steel pipes and tubes are hollow, corrosion-resistant products manufactured as seamless or welded sections for pressure, structural, and hygienic services. TeCarve is a manufacturing-backed supplier and stockist of stainless steel tubing, with production sites in Foshan and Wenzhou, China. The company exports pipe and tube to more than 50 countries, including the USA and Germany, manufacturing to ASTM A312, EN 10216-5, and EN 10217-7. Buyers can order custom sizes in 304, 304L, 316, and 316L with complete export documentation.

Export Experience for the US and EU Markets

TeCarve exports stainless steel tube to more than 50 countries, including the USA, Germany, UAE, Brazil, and India. US and EU buyers receive product manufactured to ASTM A312 or EN 10216-5, with packing and documentation adapted for sea or air freight. The export team provides EN 10204 3.1 mill test certificates on every batch, so buyers can verify grade and chemical composition.

Manufacturing-Backed Supply Chain

TeCarve controls production across two Chinese factories: Foshan (welded, coiled, heat exchanger, and sanitary tube) and Wenzhou (seamless, heat exchanger, thick-walled, and sanitary tube). With combined annual capacity of 10,000 tons, the company can supply round, square, rectangular, and special-shaped stainless steel tubes in 304 and 316L. Trial orders from 100 to 300 kg are accepted, and production lead time is 10 to 25 days after deposit.

304 and 316L Stainless Steel Grades

According to ASTM A240, grade 304 contains 18.0–20.0% chromium and 8.0–11.0% nickel with a maximum carbon content of 0.08%. Grade 316L adds molybdenum and restricts carbon to a maximum of 0.03%, improving resistance to pitting and corrosion in chloride environments. TeCarve confirms each heat through chemical analysis and mechanical testing, and the mill test certificate lists the exact element percentages.

Custom Sizes and Special Shapes

TeCarve accepts custom size orders for seamless, welded, capillary, needle, coiled, oval, and heat exchanger tubes. Tubes can be cut to length, clamped, polished, or bent to customer drawings. The tecarvepipes.com product list includes low-fin, corrugated, and decorative profiles, and each custom order is documented with dimensional inspection results before shipment.

Quality Management and Testing

TeCarve operates under an ISO 9001 quality management system. Each stainless steel tube is inspected using chemical analysis, mechanical testing, hydrostatic testing, eddy current testing, and dimensional inspection. When required, the buyer receives an EN 10204 3.1 mill test certificate, or 3.2 with independent inspection.

Surface Finishes for Process and Architecture

Surface finish affects corrosion resistance and cleanability. TeCarve supplies pickled and annealed tube, polished finishes from 180 to 400 grit, mirror (bright annealed) finishes, and matte or satin surfaces. For food, beverage, and pharmaceutical plants, sanitary tube is available with smooth internal surfaces and tight tolerances. Custom finishes are produced on request.

Export Logistics for Global Delivery

TeCarve works on FOB, CIF, CFR, and DDP incoterms, with payment by T/T, L/C, or bill of lading. All exports include commercial invoices, packing lists, certificates of origin, and mill test certificates. Because the company ships on regular schedules to the US and EU, buyers can expect predictable freight and customs clearance.

Grade Comparison for Stainless Steel Tubes

Grade	C% max	Ni%	Cr%	Key Property	Best For
304	0.08	8.0–11.0	18.0–20.0	Excellent formability and corrosion resistance	Food processing, architectural trim
304L	0.03	8.0–12.0	18.0–20.0	Low carbon prevents sensitisation after welding	Thick welded sections, tanks
316	0.08	10.0–14.0	16.0–18.0	Molybdenum improves pitting resistance	Chemical process, marine equipment
316L	0.03	10.0–14.0	16.0–18.0	Low carbon plus molybdenum for aggressive chlorides	Heat exchangers, pharmaceutical
321	0.08	9.0–12.0	17.0–19.0	Titanium stabilised for high temperatures	High-temperature exhaust, 800°C service

How to Choose the Right Grade for Your Application

Determine the fluid or environment: acidic, chloride, sanitising, or high-temperature conditions.
Assess temperature range and pressure rating: seamless tubes to EN 10216-5 for high-pressure steam.
For welding, choose low-carbon grades 304L or 316L to avoid intergranular corrosion.
For marine or chemical exposure, select molybdenum-bearing 316L or higher alloys.
Review surface requirements: sanitary and food lines need fine-polished or mirror finishes.
Verify mechanical properties and mill certificates: request EN 10204 3.1 documentation.
Match wall thickness and OD to pressure calculations using ASTM A312 or EN 10216-5 formulas.

Frequently Asked Questions

Do you supply stainless steel tubes to the US and EU?

Yes. TeCarve exports stainless steel pipes and tubes to 50+ countries, including the USA and Germany. For US and EU orders, we supply ASTM A312 and EN 10216-5 compliant products with EN 10204 3.1 mill test certificates. Custom sizes are available from 100–300 kg trial orders.

What is the difference between 304 and 316L stainless steel?

304 contains 18–20% chromium and 8–11% nickel, giving good general corrosion resistance. 316L adds molybdenum (2–3%) and has lower carbon (max 0.03%), which improves resistance to chlorides and prevents weld decay. For salt-water or chemical exposure, 316L is preferred.

Can you provide food-grade stainless steel tubes?

Yes. TeCarve supplies sanitary tubes in 304 and 316L with polished (180/240/320/400 grit) or mirror finishes designed for food and beverage plants. The smooth internal surface resists bacteria build-up and allows cleaning-in-place. Mill test certificates are provided to confirm grade purity.
