Stainless steel tubes can withstand corrosive or chemical environments and high temperatures. It means they are safe for long-term use. You can find SS tubes in automobiles, food processing equipment, water treatment facilities, oil and gas processing, and other industries.
1. Conveying pipelinefor fluid and gas such as water, drainage, oil, natural gas, etc.
2. Tubes for heat exchangers,boilers, condensers,
3. Construction uses, such as stair handrails, guardrails, windowsand gates, etc.
4. Foodprocessing or sanitary uses, medical and petroleum industries, etc.
There are more than 60 grades of stainless steel. SS 304 seamless pipe and SS 316 seamless pipe are the most common types. Both of them are available in Wanzhi Steel. Next, let’s see what is the difference between them.
SS 304 contains 18% chromium and 8% nickel, while SS 316 is made of 16% chromium, 10% nickel and 2% molybdenum.
Because of the added molybdenum and nickel elements in 316, SS 316 seamless pipe is more expensive than SS 304 seamless pipe. But in the long run, SS 316 seamless pipe is more cost-effective because it is more resistant to corrosion.
SS 304 seamless pipe features good processing performance and high toughness. SS 316 seamless pipe has superior corrosion resistance and high-temperature resistance.
SS 304 seamless pipe is widely used in water piping, indoor enclosures, kitchen equipment, decorative trim, etc. SS 316 seamless pipe is ideal for chloride and acidic environments, such as petroleum, chemical piping and equipment, marine equipment, commercial kitchen appliances, etc.
The following is the manufacturing process of stainless steel seamless tubes for your reference.
Round pipe billet → heating → perforation → three-roll slant rolling, continuous rolling or extrusion → deburring → sizing (or reducing) → cooling → straightening → hydrostatic test (or flaw detection) → marking → storage
Round pipe billet → heating → piercing → beating → annealing → pickling → oiling (copper plating) → multi-pass cold drawing (cold rolling) → billet → heat treatment → straightening → hydrostatic test (flaw detection) → marking → storage
