1. Self/double-bow casing centralizer
2. API spec. 10 D
3. Spring made of 65Mn.
4. Non-welded bow spring centralizer.
Description:
Our company provides various non-welded bow spring centralizers, which are designed and manufactured as per API Spec 10D.The popular styles available are non-welded single bow spring centralizer, and double-bow spring centralizer with high reliable quality. The woven centralizer is connected by pin when in use. The unfolded centralizer can be stacked flatly for convenient storage and transportation
Structure principle:
The bow-spring casing centralizer consists of circular hoops, single bow-springs and pins. A certain kind of centralizer is composed of certain bow springs accordingly. The material of bow spring complies with API standard and trade standard after thermal treatment. There are two connection methods of bow-springs and circular hoops. One is normal braided type, and measures up to international standard. The other is the type of connecting the bow-springs with the circular hoops by pins to prevent circular hoops and bow-springs from Loosing under the high pressure in casings.
Characteristics:
Super-strengthen spring steel ,
Model processing, no rivet , no welding
Starting and resetting force conform to API standard.
Easy for installation.

1.Good quality and competitive price
2.Cement plug for well cementation accessories
3.Bottom / top plug.
Usage: The cementing plug is used to separate the cement slurry from the mud. It can prevent the mud from blending into the cement slurry to influence the cementing quality.
Structure characteristics:
There are two kinds of cementing plug: Conventional cementing plug and special cementing plug. Conventional cementing plug is divided into Top plug and Bottom plug. Special plug has Top/Middle/Bottom plug used in two-stage cementing, drill pipe plug and hollow plug used in drilling liner cementing and composite plug used in composite casing.
