High Pressure Seamless Steel Pipe for Chemical Fertilizer Equipment

This steel pipe is applied to the chemical fertilizer equipment for conveying high temperature and high pressure fluid. It is often used in the chemical equipment with the working temperature of -40℃ to 400℃ and with the working pressure of 10 Ma to 30Ma. JST seamless steel tube for chemical fertilizer equipment is made from high-quality carbon structural steel and alloy steel. We adopt hot rolling and cold drawing manufacturing techniques to produce this kind of steel pipe.

Delivery Status We deliver seamless steel tube for chemical fertilizer equipment in the following status:

• For 20# and 16Mn grades of steel pipes, we deliver them in normalizing state.
• For 12CrMo grade of pipes, we deliver them in normalizing state (900℃ to 930℃) and tempering state (670℃ to 720℃). The soaking time or duration of time of periodic furnace is two hours while continuous furnace is just one hour.
• For 12Cr2Mo grade of seamless steel tubes, we deliver them in normalizing state (900℃ to 960℃) and tempering state (700℃ to 750℃). The soaking time is more than one hour.
