RTJ-DTG3 is suitable for casing in OD above 14 in. RTJ-DTG3 is a coupled connection. The thread is cut directly into the pipe and the coupling. The risks associated with weld-on connectors are eliminated.
Our pipe base screens are manufactured on international standards. The screen jackets are manufactured by spirally wounding narrow faced V-Wire around a cage of longitudinal support rods. Each intersection point of these wires is fusion welded.
Premium Casing & Tubing RTT-3Q
Coupling connection type, the connection strength reaches to or over that of pipe body.
A crossover sub is used to crossover from one connection size to another or as the disposable component used to extend the connection life of a more expensive drill stem member. Cross-over sub is mainly a short sub assembly which is used to enable the connection of two components with differing thread types or sizes.
The continuous-slot well screen is widely used throughout the world for water, oil, and gas wells, and is the dominant screen type used in the water well industry.
Precise Punched Slot Screen (PPS)
PPS screen is a proven screen technology with high performance for sand control and is an upgraded technological alternative for slotted liner and wire-wrapped screen. It is also suitable for coarse sandstone formations and open hole horizontal wells.
Couplings are short subassemblies used to enable two components with the same connection and size to be connected. Couplings are also known as loose coupling and spare coupling.
Pup joints are non-standard lengths of piping used to adjust the height of full length tubing, or casing strings.
TypeZR70-1 Direct wire-wound screen pipe Machine
Directly wire-wound screen pipe machine is a large mechanical equipment for processing wound screen pipe. With this equipment ,the wire can be directly wounded & welded on the peforated casing. It has the characteristic of high processing accuracy and good welding synchronization.
