SHORT RIGID CENTRALIZER
SHUANGJIA
Short Rigid Centralizer is the most popular one, manufactured of cast iron,
fixed on casing by screws, and its mechanical properties meeting the downhole
requirement. This type of centralizer is mainly suitable for vertical well, low
cost and wide application.
/MATERIAL:
Cast Steel
/SPECIFICATION: For 4-1/2" to 20"
WIDE-BLADE RIGID CENTRALIZER
SHUANGJIA
Wide-blade Rigid Centralizer is a special one, manufactured of cast iron, wide
centralizing blade, large bevel angle, which can prevent damaging wellbore, and
facilitate in passing through difficult section; it can be fixed on casing by
screws or stop collar, and its mechanical properties meeting the downhole
requirement. This type of centralizer is mainly suitable for irregular wellbore
or deviated or horizontal well.
/MATERIAL:
Cast Steel
/SPECIFICATION:
For 4-1/2" to 20"
GENERAL RIGID SPIRAL CENTRALIZER
SHUANGJIA
General Rigid Spiral Centralizer is manufactured of aluminum alloy, and fixed
on casing by stop collar. Its mechanical properties meeting downhole
requirement, with light weight and large bevel angle, it is suitable for
small-size directional well.
/SPECIFICATION: For 4-1/2" to 20"
WIDE-BLADE SPIRAL CENTRALIZER
SHUANGJIA
Wide-blade Rigid Centralizer is a special one, manufactured of aluminum alloy,
fixed on casing by stop collar. Its mechanical properties meeting downhole
requirement, light weight, wide centralizing blade and large bevel angle, it
can prevent damage to wellbore, and facilitate in passing through difficult
section. This type of centralizer is mainly suitable for irregular wellbore or
deviated or horizontal well.

Straight
blade Rigid Centralizer
SHUANGJIA
Straight Blade Solid Centralizers provide the right features for getting a good
primary cementing job with maximum casing/wellbore standoff. There are constructed
of one-piece high strength corrosion resistant cast aluminum and also
non-sparkling Cast aluminum. Straight blade solid centralizers provide ultimate
drag and torque reduction with maximum fluid bypass. With low friction factor
it’s withstand high wellbore temperatures while providing maximum horizontal
standoff. There are wellhead friendly and have high impact with shock
resistance, along with optimum tensile and yield strength.
/MATERIAL: Cast Steel or Aluminum Alloy
/SPECIFICATION: For
4-1/2" to 20" Casing
