Sprocketed conveyor rollers are ideally suited to either pallet or heavy duty conveyors. The rollers can be supplied with single sprockets for tangential drives or double sprockets for roller to roller drives.

TIANHE Fixed Diameter Hole Openers are designed for use in soft clays and shales to medium-hard shales and limestones. It is particularly effective in sticky formations where balling problems are encountered. Three jets with replaceable nozzles continuously clean the tool's cutting structure, clearing debris buildup and increasing penetration. Fixed Diameter Hole Openers are used in the following conditions:

non-rotating stabilizer (rubber sleeve stabilizer) is able to avoid blade wear and wall damage during drilling. The non-rotating stabilizer consists of mandrel, copper washer, rubber sleeve, spacer sleeve and self-locking lower sub.

A lift Sub enables safe and efficient handling of straight OD tubulars such as drill collars, shock tools, jars, directional equipment and other tools by using the drill pipe elevators.

We designed every aspect of this double-acting hydraulic jar to withstand the rigors and long hours of challenging applications. Featuring an extra-long stroke length for exceptional impact and impulse forces during jarring operations, the Double-Acting Fully Hydraulic Drilling Jar  offers infinitely variable trip loads up to the maximum rating of the tool. Only a minimal load is required in both the up and down jarring directions, which is crucial in directional, horizontal, and extended-reach wellbores. This makes the jar an ideal solution for modern drilling operations.
