ASTM304 Stainless Steel Pipe201 304 316L 310S Industrial Stainless Steel Welded Pipe

# Version 1: Full Detailed Product Introduction (For Detail Page) # ASTM Standard Welded Stainless Steel Pipe | Grade 201, 304, 316L, 310S ## Product Overview Our industrial welded stainless steel pipes are produced fully compliant with ASTM A554 standards, covering four mainstream stainless steel grades: 201, 304, 316L and 310S. Adopting high-frequency seamless welding technology with internal weld bead grinding treatment, the pipes feature smooth inner and outer surfaces, uniform wall thickness, stable mechanical performance and remarkable corrosion resistance. We support customized outer diameters, wall thicknesses, fixed cutting lengths and pipe-end machining to fit all kinds of industrial, construction, chemical and high-temperature transportation projects. ## Grade Feature & Application 1. **201 Stainless Steel Welded Pipe** A low-cost austenitic stainless steel with moderate rust resistance. Suitable for dry indoor decoration, guardrails, handrails and low-pressure clean water pipelines with cost control requirements. Not recommended for coastal or corrosive environments. 2. **304 Stainless Steel Welded Pipe (ASTM Standard General Grade)** The most widely used multi-purpose stainless steel grade with balanced chromium-nickel composition. It resists atmospheric corrosion, fresh water and weak acid erosion, with stable performance at room temperature. Ideal for domestic water supply, food processing pipelines, mechanical equipment frames, architectural decoration and general industrial fluid delivery. 3. **316L Stainless Steel Welded Pipe** Low-carbon molybdenum-containing stainless steel, greatly enhanced resistance to chloride, seawater, acid and alkali media. Outstanding anti-corrosion performance in coastal, chemical, pharmaceutical and sewage treatment environments. It is the preferred material for marine engineering, chemical fluid pipelines and coastal facility piping systems. 4. **310S Stainless Steel Welded Pipe** High chromium and nickel heat-resistant stainless steel, capable of long-term service under 800℃~1200℃ high temperature with excellent anti-oxidation and anti-creep properties. Mainly used for furnace tubes, high-temperature flue pipes, heat exchanger tubes and thermal processing equipment pipelines. ## Core Advantages 1. Strictly follow ASTM production standards, complete specifications ranging from thin-wall decorative tubes to large-diameter thick-wall industrial pipes. 2. Smooth welded joints with internal bead removal, no flow blockage for medium transportation. 3. Multiple surface options: bright BA polishing, No.4 brushed matte, pickled industrial matte surface. 4. Precise dimensional tolerance for outer diameter and wall thickness, reliable pressure-bearing and tensile strength. 5. Excellent rust-proof, acid-resistant and high-temperature resistant performance for harsh working conditions. 6. Customizable services: fixed-length cutting, grooving, threading, OEM packaging and logo printing. ## Wide Application Fields - Food & beverage production, pure drinking water supply systems - Chemical, pharmaceutical, sewage and corrosive fluid transportation - Coastal engineering, seawater desalination and marine supporting pipelines - High-temperature furnaces, heat exchangers and thermal energy equipment - Construction decoration, handrails, guardrails and mechanical frames - Petroleum, papermaking, power plant industrial piping ## Technical Specifications - Executive Standard: ASTM A554, ASTM A240 - Available Material Grades: 201, 304, 316L, 310S - Production Type: Welded stainless steel round pipe - Surface Finishes: BA Bright Polished, No.4 Brushed, Pickled Matte - Customizable Items: OD, wall thickness, length, pipe end processing ## Packaging & Shipping Both pipe ends are equipped with plastic protective caps to avoid collision damage.
