Stainless steel pipes have been widely used in industrial and life fields and are deeply loved by the public.

Stainless steel tubes are generally called stainless steel capillary tube and stainless steel precision pipes. They are mostly used in chemical, oil, electronics, accessories, medical, aerospace, air conditioning, medical equipment, kitchen utensils, pharmaceuticals, water supply equipment, food machinery, power generation, boilers and other fields. Is the stainless steel tube 304 good at present? The fine tube material does not have a small tube without embroidery steel, the thickness of the thickness is different, and the thickness of the tube wall is different.

How to clean the stainless steel tube?

Immerse stainless steel pipes into heated dehydration,

Then use gas or water to circulate and rinse.

If you have a suitable size brush, scrubbing back and forth.

See Table 6-31 for allowed deviations.

Outer diameter <3.2mm

Wall thickness <0.4mm outer diameter ≥3.2mm

Wall thickness ≥0.4mm

1CRL8NI9TI should comply with the provisions in the GB/T1220 "Stainless Steel Stick" ≥550 25 35

Note: 1. Steel pipes are generally delivered in hard (cold pull, cold rolling). If you need a semi -hard state or a soft -state steel pipe need to be indicated in the contract.

2. The steel pipes of hard -state delivery do not perform mechanical performance tests.
