H & T Chemical Injection Skid


Chemical Injection Skid with Shockproof and Dual Scale Display Pressure Gauge .Which is a piece of equipment designed to inject chemicals into a system at the required pressure of the system.

N&T chemical injection skid provides low-pressure compressed air as a booster power source a pressure to keep convenience and safety. This equipment is applicated in surface low pressure, and downhole high pressure.


1)pressure compressed air as booster power source to keep convenience and safety.

2)Adopted pressure to be self-locked to adjust output pressure keeps constant in case of overshoot under air-driven pressure setting constant.

3)With shockproof and dual scale display pressure gauge

4)Equipped with a glass column and high-precision flow control valve to meet the requirements of high flow rate chemical injection.The main -material are glass and 316s to meet the corrosion-proof requirements;

5)All components, piping and valves are made of 316s or 316L, which can prevent from corrosion effectively ;It has operation schematic on the control panel, which is easy to observe and operate.
