Products Specification

Stainless steel welded pipe introduction
Stainless steel welded pipe is a pipe welded by crimping stainless steel strip or sheet, which has excellent corrosion resistance, strength and aesthetics, and is widely used in industry, construction, decoration and other fields.

Production technology

• Raw material preparation:Use stainless steel coil or strip, common materials are 201, 304, 316 and so on.
• Molding:The stainless steel strip is curled into a round or square tube blank by the forming machine.
• Welding:By TIG (argon arc welding), plasma welding or high-frequency welding, the joint of the tube blank is welded and formed.
• Weld treatment:Polish or heat treat the weld to ensure its strength and smoothness.
• Sizing and straightening:The pipe size is adjusted by the sizing machine and the straightness of the pipe is ensured by the straightening machine.
• Cut:The pipe is cut to a standard length (usually 6 meters) as required.
• Surface treatment:Polishing, drawing, sandblasting and other treatments to improve surface finish and beauty.
• Inspection and packaging:Size, weld, surface quality and other testing, qualified packaging factory.

specification

• Material: 201, 304, 304L, 316, 316L, etc
• Outer diameter: Φ6mm-Φ2000mm (can be customized according to demand)
• Wall thickness: 0.5mm-20mm (can be customized)
• Length: Usually 6 m (customizable)
• Shape: round tube, square tube, rectangular tube, oval tube, etc

Surface treatment

• Polish:Make the surface smooth like a mirror, suitable for decorative purposes.
• Divided into ordinary polishing, mirror polishing, etc.
• Wire drawing:Form a fine texture, enhance the texture, often used in architectural decoration.
• Sandblast:
• Make the surface appear matte effect, increase wear resistance.
• Pickling:Remove the surface oxide layer and improve corrosion resistance.
• Plating:A layer of other metals (such as chromium and nickel) is plated on the surface to enhance aesthetics and corrosion resistance.

peculiarity

• Corrosion resistance:Stainless steel has excellent corrosion resistance and is suitable for a variety of environments.
• High strength:The welding process ensures that the pipe has a high mechanical strength.
• Aesthetics:The surface treatment can meet the decorative needs.
• Easy to process:Easy to cut, bend, weld, convenient construction.
• Hygienic:Smooth surface, not easy to accumulate scale, in line with food and medical industry requirements.
• Lightweight:Compared with seamless steel pipes, welded pipes have thinner wall thickness and lighter weight.

Apply

• Architectural Decoration:Stair railings, guardrail, door and window frames, etc.
• Industrial field:A pipe for transporting fluids (e.g. water, gas, chemicals).
• Food and Pharmaceutical industries:Sanitary pipe for conveying food and medicine.
• Automobile Manufacturing:Exhaust pipe, structural parts, etc.
• Furniture Manufacturing:Table and chair frame, display rack, etc.
• Energy industry:For oil and natural gas pipelines.
• Environmental protection equipment:Flue gas treatment, sewage treatment equipment in the pipeline.

Stainless steel welded pipe is widely used in construction, industry, food, medicine and other fields because of its corrosion resistance, high strength, beautiful appearance and easy processing. Through different surface treatments, it can meet diverse needs, and is a multi-functional and economical and practical pipe.
