Technical FAQ
Application limits
- Can it be used for steam above 150 C?
- No. Do not use for steam above 150 C unless a written project-specific approval, rated gasket, and compatible body material are confirmed.
- Can it replace any grooved fitting without checking pipe OD?
- No. Pipe OD, groove standard, working pressure, gasket material, and certification scope must be matched.
- Is it suitable for potable water by default?
- No. Potable water use requires confirmation of coating, gasket compound, local sanitary approval, and project compliance.
- Can it be used in corrosive chemical service?
- Not by default. Chemical compatibility must be verified against the medium, concentration, temperature, and coating system.
