Bellow material choosing
| Steel Types | Properties and applications |
|---|---|
| SUS304 | General-purpose stainless steel: Used to make general chemical equipment, food equipment and nuclear power equipment, and in construction and household supplies. |
| SUS304L | 304 ultra-low carbon steel: More resistant to intergranular corrosion than 304. Used when heat-treatment after welding is not possible. |
| SUS316 | Stainless steel made by adding molybdenum to 304 for improved corrosion resistance. Used in items such as ship parts. |
| SUS316L | 316 ultra-low carbon steel: Has higher intergranular corrosion resistance. Used in areas requiring resistance to corrosion and pitting. |
| SUS317 | Higher corrosion resistance than 316. Used to make equipment for applications such as papermaking and dyeing. |
| SUS317L | 317 ultra-low carbon steel: Has higher intergranular corrosion resistance than 317. |
| SUS309S | Has higher corrosion resistance than 304. Used mainly as a heat-resistant steel. |
| SUS310S | Has higher oxidation resistance than 309. Used mainly as a heat-resistant steel.Hi |
| SUS321 | Made by adding titanium to 304 to increase intergranular corrosion resistance. |
| High Nickel alloy | Has very high oxidation and heat resistance. Used in corrosive and high-temperature environments. |

Recommended installation instructions
- Do not drop or strike carton.
- Inspect for damage during shipment, i.e., Dents, broken hardware, water marks on carton, etc.
- Store in clean dry area where it will not be exposed to heavy traffic or damaging environments.
- Do not remove shipping bars until installation is complete.
- Do not remove any moisture-absorbing desiccant bags or protective coatings until ready for installation.
- Do not use hanger lugs as lifting lugs without approval of the manufacturer.
- Do not use chains or any lifting device directly on the bellows or bellows cover.
- Do not allow weld splatter to hit unprotected bellows. Protect with wet chloride-free insulation.
- Do not use cleaning agents that contain chlorides.
- Do not use steel wool or wire brushes on bellows.
- Do not force-rotate one end of an expansion joint for alignment of bolt holes. Ordinary bellows are not capable of absorbing torque.
- Do not hydrostatic pressure test or evacuate the system before installation of all guides and anchors.
- Do not exceed a pressure test of 1 1/2 times the rated working pressure of the expansion joint.
- Do not use shipping bars to retain thrust if tested prior to installation.
