What materials are compatible with high-chloride fluid systems for these parts?

Use stainless steel 316 components (e.g., K4142009AA, K4143018AA) to avoid stress corrosion cracking (SCC). Avoid carbon steel and brass parts in high-chloride environments.

How often should O-rings (Z15010200178AA) be replaced in high-pressure 60MPa systems?

Replace FKM O-rings every 6–12 months, or immediately if leakage, hardening, or cracking is found. For continuous high-pressure operation, shorten replacement intervals to 4–6 months.

Can the P9912700209AA straight pipe (L=11800) be used in high-temperature (＞200℃) applications?

No. The P9912700209AA uses API 5L Grade B carbon steel, which is only suitable for temperatures up to 150℃. For ＞200℃ use, replace with alloy steel pipes (e.g., K46201156001AA).
