2. Float Collar The FC float collar has its shell made of 35CrMo structural alloy steel. It is applicable to casing assembly as a guide for the casing string. The float collar can accurately control the height of cement plug inside the casing and improve quality of cementation. The internal parts are readily drillable, and the float collar can resist high back-pressure up to 35Mpa.
2. Float Shoe The FS float shoe comes with recyclable extension tubes, and its shell is made of 35CrMo structural alloy steel. The float shoe suits vertical wells, highly deviated wells, horizontal wells, with resistance to high back-pressure of 35Mpa.
  The valve provides stable performance and large pressure-bearing capacity.
2. Casing Centralizer The casing centralizer is made by mould pressing instead of welding or using rivets, and thus has firm structure.
  The centralizer is detachable, so it is easy to transport and install.
  Both the starting force and reset force are in line with API 10D standards.
2. Two Stage Cementing Tool The opening pressure for the two stage cementing tool is adjustable, and the operation is not subject to the hole angle.
  The inner diameter of upper/lower sub is the same as that of casing, but smaller than that of the closing sleeve. The chances of damages to the closing sleeve can thus be minimized.
2. Cement Head The double plug cement head suits continuous two stage cementing, in addition to general well cementation.
  The lever type indicator shows whether the rubber plug enters the casing through the double plug cement head. This facilitates proper operation by users.
2. Liner Hanger When the liner reaches the predetermined position, it will hang, reverse, cement and bump the well. Then it raises the driller and makes the block stretch out to set on the up end of tie-back sleeve, the driller under which shears the pins. The roller will expand under the action of external force to seal the upper casing and tie-back sleeve.
2. Plug The SS top plug and DS bottom plug are designed and manufactured in compliance with SY5394-91 standards. The core, made of aluminum alloy, has great drill capability. The plug is made of imported nitride butadiene rubber and offers oil, acid-alkali resistance. Due to unique structure, the plug provides excellent scraping and displacement.

Cementing tool is essential when drilling wells. Through well cementation by the cementing tool, casing pipes are fixed inside the well to drain water or other fluids from the well.

As a specialized cementing tool manufacturer in China, Rundong provides float collar, plug, cement head, and more. The cementing tool is made of superior raw materials to ensure reliable performance. For example, the plug, made of imported nitride butadiene rubber, offers strong oil resistance and acid-base resistance. The float collar uses 35CrMo structural alloy steels as raw material to ensure excellent mechanical property. In addition, modern management mode helps result in optimized distribution of enterprise resources, thus reducing our cost. Hence, our high quality manifold, mud pump parts, oilfield components, etc. are available at affordable prices. In order to better serve our customers, we offer customized equipment and accessories. We at Rundong warmly welcome global buyers to try our petroleum machinery. Our staff sincerely looks forward to working with more international customers.
