Product introduce



Elastic centralizer is often used in oil and gas fields to keep the casing centered in the well to improve the cementing quality.


The existing elastic centralizer is mainly divided into welding type and clasp type.


Its disadvantages are as follows: due to the welding structure or clasp structure, its firmness is affected by many aspects, and it may fall off in use, bringing hidden dangers to the use of centralizer.The traditional elastic centralizer can also bear limited pressure, which is easy to be damaged when the pressure is too high. Moreover, when the elastic centralizer needs to shrink internally through the smaller diameter section, its elasticity and strain are insufficient, which makes it difficult for the casing to be centered in the well and greatly affects the cementing quality.


Therefore, puyang sanli integrity oil equipment co., LTD. Independently developed a new type of integral elastic centralizer to effectively solve the use of the site problems.


Compared with other types of centralizer, this new type of centralizer has the characteristics of beautiful structure, light weight, strong centralizing force, not easy to fall off and wide application range, which greatly improves the cementing quality.
