Combining the advantages of forging overcoat resistance to wear and high chromium wear-resistant anti-corrosion than that of national standard.70 percent of liners sold to united states¡¢russia¡¢menggu¡¢kazakhstan and in the middle east.
¡¡¡¡for satisfying the need of oil field drilling and reducing drilling cost, our company manufacture jytd-10 3/4*5 1/2-21 simple casing heads for many years experience.
¡¡¡¡usage:
Connecting outer pipe thread directing to the surface casing pipe thread in the drilling operation.
The casing weight in addition to the surface casing can be hanged by the hanger.
ations, for example, remedial cementing from the side of the hole and hiting fluid into the side of the hole to to balance the internal pressure at acid-fracturing.
It is controled by hydraulic to reach seat hanging.
Working with sq seting-ball carrier, it is suitable for applications in horizontal and highly-deviated wells.
Sealing element is made of nitrle/fluorine rubber and its temperature can reach 120¡æ/200¡æ.
Main parts are fabricated with high-strength alloy steel providing high resistance
Our company can offer various types of mud pumps cylinder head including f series, 3 nb series and others.Its material is 35crmo. Cylinder head is the main parts in the fluid end of drilling mud pump system.
Combining the advantages of forging overcoat resistance to wear and high chromium wear-resistant anti-corrosion inner sleeves.The overcoat is a forged steel. The hardness of high chromium inner after heat treatment reached 62 hrc. The company offers all kinds of premium chromium liners with domestic sl3nb, 3 nb, f three series pump, and abroad
Spring casing centralizer is pressed into shape by mouding instead of welding and rivet. It has the advantages of simple structure, safe and reliable, high strength, good elasticity and convenient use. It can be widely used in vertical and deviated well in the casing work. Starting force and restoring force conform to api standards.
Spring casing centralizer is divided into single bow, double bow and three bow.
Spring centralizer is composed of circular hoop, bowspring and dowel. Bowspring can reach api standards after heat treatment which material is 65 mn.
