Zero-Leak Welded Integrity: Our welded pipes utilize advanced automatic TIG/Plasma welding with online internal weld bead flattening, matching 100% of the parent metal's structural yield strength.
Ultra-Reliable Seamless Pressure Ratings: Cold-drawn and cold-rolled seamless pipes feature a uniform grain structure, perfect for high-vacuum, high-pressure, or explosive gas/fluid lines.
Excellent Corrosion Resistance: Pure raw materials (guaranteed Nickel and Chromium content) prevent premature pitting in acid, alkali, and high-chloride environments.
Chemical & Petrochemical: Corrosive chemical transport, oil and gas pipelines, refineries, and offshore platforms.
Water Treatment & Desalination: Municipal water networks, desalination plant piping, and wastewater facilities.
Food, Beverage & Pharmaceutical: Sanitary process piping, breweries, and pharmaceutical pure water loops.
Power Generation: Heat exchanger tubes, condenser pipelines, and cooling tower networks.

We customize your piping to minimize local preparation and onsite welding times:
Surface Conditions: Pickled & Annealed (Industrial Acid-Wash), Bright Annealed (BA Finish), Satin Brushed, Mirror Polished.
End Preparation: Plain ends square cut and deburred, or customized Beveled Ends for instant socket/butt welding.
Precision Deep Processing: Precise length cutting, threading, bending, and slotting according to your piping blueprints.
Production Facility: 70,000+ Sqm advanced pipe-making and cold-drawing plant, operating both automated continuous welding lines and heavy hydraulic cold-drawing machines.
Massive Standing Tonnage: Over 10,000 tons of ASTM A312 304 and 316L master stock in Schedule 10 and Schedule 40 thicknesses, ready for immediate loading.
Direct Mill Pricing: True direct manufacturer source. Lower your procurement overheads by removing middleman trading agencies.
Pressure Safety Tests: 100% Hydrostatic testing or NDT (Non-Destructive Eddy Current / Ultrasonic testing) applied to every single industrial pipe.
Chemical Component Verification: Strict on-site PMI checking via hand-held spectrometers to verify exact alloy chemistry before packing.
MTC 3.1 Traceability: Authentic Mill Test Certificate (MTC EN 10204 3.1) accompanying every container. Third-party inspections (SGS, BV, TUV) are fully welcome.
Worldwide Shipping: Decades of experience supplying engineering distributors and EPC projects across the Americas, Europe, Middle East, and Asia.
Tariff Management: Expert documentation handling for official Certificates of Origin (Form E, RCEP, CO, FTA agreements) to minimize or eliminate your local import customs taxes.
Flexible Terms: Handling standard FOB China, CIF destination ports, DDU, and direct door-to-door DDP logistics.
End Protectors: Plastic pipe caps fitted on both ends of every pipe to prevent internal contamination and preserve beveled edges.
Protective Bundling: Wrapped in moisture-proof woven plastic material and bundled securely with heavy steel strapping.
Heavy Duty Crating: High-precision or polished piping packed inside solid fumigated wooden crates or steel channel frames to eliminate transit movement.
Q: What is the main difference between Schedule 10 and Schedule 40 stainless steel pipes?
A: "Schedule" dictates wall thickness. Schedule 10 is a light-wall piping system widely chosen for lower-pressure fluid handling to save on material costs and weight. Schedule 40 features a thicker wall, ideal for high-pressure or heavy structural industrial applications.
Q: How can we guarantee that your welded pipes will not split at the weld seam under pressure?
A: All our ASTM A312 welded pipes undergo mandatory automated non-destructive eddy current testing or hydrostatic testing. The weld seam is as strong as the parent metal and can handle standard pressure ratings flawlessly.
Q: Do you accept small trial quantities for non-standard pipe specifications?
A: If we have the master coil or pipe size in stock, our MOQ can be as low as 1 piece. For specialized custom cold-drawn sizes, production typically requires 2–3 tons.
