In oilfield production industry, pump barrels are nether less exposed to very harsh conditions such as:
High corrosive environment (H₂S / CO₂)
Sand produced and abrasive particles
High water production and chemical fluids
Deep well high-pressure operations
Brass chrome plated pump barrels are designed to brass's inherent corrosion resistance, use the high hardness of chromium plating for wear protection,
Finally, the inner surface is tightly honed to improve sealing.
Brass as a base material has better performance in H₂S and CO₂ environments than regular steel.
Hard chrome plating greatly enhances the toughness of surface zones in abrasive sands.
Lifespan usually 2-3 times more than that of ordinary carbon steel barrels.
API 11AX Standard Compliance，Compatible with all international sucker rod pump systems.

Highly-corrosive oil wells (H₂S / CO₂ environments)
Heavy oil wells need reliable sealing
Sandy oil wells with abrasive particles
Well deep pump systems
Sea oilfield operations
Very suitable for the wells where normal steel barrels break down very often
Different well conditions require different materials:
Chrome Brass Barrels: Best for high corrosion + moderate sand conditions
Steel Chrome Barrel: Suitable for low corrosion environments
Special Alloy Barrel: Used for extreme high temperature or chemical conditions
We provide material selection support based on your well data.

Q1: Can chrome brass barrels be used for high concentrations of H₂S?
A1: Absolutely, brass is much more resistant to H₂S corrosion than plain steel.
Q2: What is the service life of chrome brass barrels?
A2: It can last 2-3 times longer than a normal steel barrel under the same working conditions.
Q3: Is it suitable to use in wells with sand?
A3: Certainly, chrome plating greatly enhances the wear resistance of equipment operating in sand-producing conditions.
