Choke bean used in the positive chokes for controlling the
flowrate,and are usually mounted on or close to the wellhead
equipment.High pressure gas/oil, with abrasive sand minerals passes
through these chokes at high speed causing rapid wear. Bean chokes
contain a replaceable insert, or bean, made from hardened steel or
similar durable materials.

Main features of our choke beans
1. Choke bean size: 4/64" ~ 192/64" in increment with 1/64".
2. Medium: oil, natural gas,water, sand, including H2S
3. Tungsten carbide and ceramic choke bean are all available.
4. The bonnet connection form is union, which is more convenient to
replace bean.
5. The bean orifice is made of ceramics or hard alloy with wearing
resistance and washing resistance.
6. Can be customizable.
