316 Stainless Steel Welded Pipe
Product Description
316 stainless steel welded pipe contains 2%-3% molybdenum, which makes it have better corrosion resistance in acidic, alkaline and salt corrosion environments. It is more corrosion-resistant than 304 stainless steel pipe and can work stably in the range of -196℃ to 800℃. Therefore, 316 stainless steel structural welded pipe is often used in seawater treatment equipment, chemical containers and other fields.

GNEE's Advantages
GNEE has industry certifications: NACE MR0175 (anti-sulfide stress cracking), ASME BPVC (pressure vessel), FDA (food contact). Ultrasonic flaw detection (UT), hydrostatic test (1.5 times the working pressure) and penetrant testing (PT) are used to ensure that there are no welding defects.
