Puyang Zhongshi Group Co.,Ltd

This kinds of bow spring centralizer is designed for higher restoring force and lower starting&running force to center the casing in vertical and deviated wells.The nonweld centralizers are available in single bow and double bow(dual contact) type.

ZHENGZHOU,DEC 07,2016-Casing centralizer is a mechanical device around the casing to  keep the casing from contacting the wellbore walls.The continuous 360 degree space around the casing is better to make the cement seal the casing to the hole wall.Casing centralizers play the importanct role in improving the cementing quality by preventing mud channeling and poor zonal isolation.Simply speaking casing centralizer is used for centralizing casing( also called running of casing ) and the prevention of differential sticking.

Casing centralizer is manufactured widely during oilfield serive. It is estimated that 8 million casing centralizers are manufactured and used every year all over the world wide.When casing centralizer manufacturers hear the number of centralizer,they would like to increase the demand for casing centralizers.However ,on the other hand,cementing operators may be interested to ask why we need so much casing centralizers.

Puyang Zhongshi Group,mainly deals in manufacturing of rigid centralizers,such as slip on rigid centralizers,line band rigid centralizers and so on.These casing rigid centralizers are used where casing centralization is the main consideration, such as to centralize large casing strings to facilitate the cutting of casing during well abandonment.Straight blades and spiral blades are available.At the same time,we can design the height of rigid centralizers according to customer requirement and wellbore condition.So Puyang Zhongshi Group can provide you with long and short rigid centralizers with different blade types. There are some featured  following slip on rigid centralizers with solid body.Generally speaking it is steel or aluminum body construction,the features are like shock, impact, and corrosion resistant, high tensile and yield strengths. Advantages and benefits of spiral blade rigid centralizers 1.45-degree angle producing maximum fluid swirl and debris. 2. Reducing gouging and scraping of formation. 3.Maximum wall contact. 4.Spiral blades allow better cement coverage.

Advantages and benefits of straight blade rigid centralizers 1.Easy to install. 2. Less flow restriction than other centralizers. 3.Unaffected by lateral load. 4.Casing moves freely within the centralizer. 5.Reducing differential sticking and casing contact.

Bow spring centralizers play the important role in the casing centralization for primary cementing.It hleps center the casing in the wellbore during cementing operation and allow the cement displacement. The degree to which the casing is centered (standoff) depends on the performance of the centralizer and the spacing between the centralizers installed on the casing OD.

But there still are some difference between single bow spring centralizer and double bow spring centralizer.The double bow (dual contact) spring centralizer is designed for small-clearance casing-to-hole size applications. This kinds of dual contact bow spring centralizer is in holes up to 1/2 in. smaller than the standard bow centralizer’s nominal OD. Because of its high restoring force with very little spring deflection, the dual-contact bow spring centralizer is excellent for deviated and horizontal wellbores. The dual-contact centralizer should only be installed between a collar and stop ring—never over a casing collar.

The drillpipe centralizer is  for centralizing drill pipe when for inner-string cementing operations. The drilling centralizer is with long,extend straight bow springs which are welded on the hinged end collars.

ZHENGZHOU, OCT 11,2016-A full range of cast rigid centralizers are designed and manufactured from Puyang Zhongshi Group,these rigid centralizer is used for centralizing casing

from standard vertical well configurations to highly deviated and horizontal wells.The rigid centralizer is made of steel or aluminum body construction with casting

technology.This kinds of centralizer is with straight blades and spiral blades which are to help clean the fluid and distribute the cement in the wellbore. Puyang Zhongshi Group supplies the cast rigid centralizers including standoff band rigid centralizer(straight blades rigid centralizer),spiral blades rigid centralizer and

aluminum alloy spiral blades rigid centralizer.For straight blades centralizer,it is widely used to centralize large casing strings to facilitate the cutting of casing during

well abandonment.For spiral blades centralizer,the material of rigid centralizer is abrasion resistant mild steel and it provides maximum standoff as soon as possible,the angle

of spiral blades is 45degree to increase fluid passage and provide 100% circumferential coverage.For aluminum alloy spiral rigid centralizer,it is made of high strength,

corrosion resistant cast aluminum and then can withstand more load during running and cementing operation. The setscrews are added on the rigid centralizer and to increase the holding force or separated slip on stop collar is available according to request from customers. All kinds

of standard centralizer sizes are available , tested and validated to API Specification 10D,some special sizes can be designed and manufactured. Ordering suggestions to provide right size and type of cast rigid centralizer,please specify as follows: 1.The casing centalizer is cast rigid centralizer or not. 2.Casing O.D on which the rigid centralizer will be used 3.Hole size or casing I.D in which the equipment will be placed 4.The material of cast rigid centralizer,mild steel or aluminum alloy 5.The blade style of rigid centralizer,straight blade or spiral blade 6.The height of rigid centralizer,long or short 7.The setscrews is integral with rigid centralizer or separated stop collar

ZHENGZHOU, OCT 09,2016-As API certified casing centralizer manufacturer in China,Puyang Zhongshi Group has got API 10D certificate since 2011 and supplies all kinds of casing

centralizers like bow spring casing centralizers and rigid casing centralizers.The close tolerance casing centralizer is one of casing centralizers,sometimes we call it slip on

welded casing centralizer.This kind of centralizer  is well suited for the need of  a close tolerance centralizer for use in tight annulus applications where there is some well

in a tight spot.The great advantage  of casing centralizer is enough restoring forces after passing through those restrictions, while keeping the starting and running forces at

a minimum. The close tolerance casing centralizer is composed of bow profile and lap-welded end collars with setscrews to increase the holding force.Bow is welded to the collars in order

to offer reliable, durable, and low profile for this casing centralizer. Slip-on configurations have end collar to protect against damage and provide minimum endcollar

height.Setscrews is installed on the casing centralizer integrally and can help customers save the separated stop collar cost and operation time. The close tolerance casing centralizer is applied in close-tolerance cased-hole when your drilling project in a tight spot.You do not need casing centralizer sub at all. Sizes

from 5-1/2 to 20inch are available,tested and validated to API Specification 10D. The close tolerance casing centralizer from Puyang Zhongshi Group will help you improve the

cementing integrity.For more information,please send email  :[email protected]

ZHENGZHOU, SEPTEMBER 27,2016-Puyang Zhongshi Group supplies several styles of welded bow centralizers with hinged collar and slip on collar.According to production experience from us and purchasing experience from customers,it is better choice to use the hinged welded bow centralizer whose feature is easy to be installed over stop collars or couplings on all standard casing grades and provide casing centralization in the wellbore for vertical and horizontal wells.Therefore this kinds of welded bow centralizer is designed for high performance and strength under most of well conditons.

The bow of welded bow centralizer is made of high grade spring steel which is heat treated,can provide maximum standoff during cemention and any bow height is available to provide excellent restoring forces.The rigid end collar is hinged type,it provide solid support for end bands,it is aslo easy installation.

The difference between welded bow centralizer and non welded bow centralizer is that the bow springs of welded type centralizer are welded on hinged end collar.In order to increase the holding force ,the integral set screws are added into collar to assist the welded straight bow springs.So the separated stop collar is not required  with the bow centralizer.
