JIS G3448 Light Gauge AISI 316 SS Thin Wall Tube for Ordinary Piping
1. Scope
This Japanese Industrial Standard specified the stainless steel pipes (hereafter referred to as "pipes") used for the piping of water supply, hot water supply, drainage, cold and hot water supply and there, of which maximum working pressure is 1MPa of under.
Remarks: The standards cited in this Standard are shown in Attached Table 1.
2. Grade and symbol
AISI 316 SS Thin Wall Tube shall be classified into two grades, and their symbols shall be as given in Table 1.
Table 1. Symbol of grade
Symbol of grade | Use (Informative reference) |
SUS 304 TPD | For ordinary piping of water supply, hot water supply, drainage, cold and hot water supply, etc. |
SUS 316 TPD | For use to require corrosion resistance higher than SUS 304 to cope with water quality, environments, etc. |

3. Materials and method of manufacture
The materials of AISI 316 SS Thin Wall Tube and the method of manufacture shall be as follows:
3.1 Materials steel plates or stripe used for the pipes shall be as specified in either JIS G 4304, JIS 4305
3.2 Method of manufacture The pipes shall be manufactured by automatic arc welding, laser welding, or electric resistance welding, and shall. as a rule, be not heat-treated. The heat treatment, if applied, shall be made by solution treatment to be followed by acid cleaning or similar treatments, Heat treatments other than the solution treatment shall be as agreed upon between the purchaser and supplier.
