ASTM A270 Compliant Sanitary Tubing

Our polished stainless steel sanitary tubing meets ASTM A270 standards, ensuring superior quality and performance. We start with cold-rolled stainless steel strips, meticulously controlling chemical elements to enhance weldability and durability. Each weld bead undergoes cold-working to achieve a seamless finish, providing a smooth appearance with minimal visibility of the longitudinal weld. To maintain structural integrity, our tubing undergoes annealing in a controlled atmosphere, preserving its pristine condition for demanding sanitary applications.

Production

1. Annealing

We anneal our tubes with 1100 degree Centigrade thereafter cool down with at least 10 seconds, depending on their outside diameter.

Key to annealing tubes is to reengineer the molecules to return as they are used to be before welding. The tubes are strengthened as a result of this method.

2. Pickling

We pickle our tubes in the diluted acid around 15 minutes for cleaning textures.

3. Polishing

For stainless steel tube, the smooth texture is not only shiningly elegant but also easy to maintain, clean up and sterilize in order to retain long hygienic condition. We used abrasive with high number of grit to smoothen the texture. There are two specifications of our products, which are always polished.

Firstly

ornamental tube, ASTM A-544, is normally polished by abrasive with grit number 400 for our products in stocks.

Secondly

sanitary tube, ASTM A-270 which is mostly used in food industry, requires to be polished both inside and outside textures. Normally it uses abrasive with grit number 180 for both inside and outside texture, while Toyo Millennium use grit number 320 and 180 for the inside and outside respectively.

For Roughness value of the inside texture, you can check it out in section, Roughness Test, one of our quality assurance tests.

4. Marking

On our marking, we put information which is company's name, grade, heat number, and specification number. There are 3 types of marking.

For sticker label.

We put it on outside of sanitary tube ASTM A-270 and inside of ornamental tube ASTM A-554.

For ink-jet screen.

Used for identifying heat exchanger service tube ASTM A-270, ASTM A-249 and A-269.

For electric arc marking.

All types, only for special requirements by customers order.
