Premium tubing has gained popularity in various industrial applications due to its outstanding performance. Premium tubing is manufactured using high-quality materials, making it highly resistant to corrosion, erosion, and abrasion. It also has excellent strength and durability, making it perfect for use in harsh and demanding environments. Furthermore, premium tubing is easy to install and maintain, making it cost-effective and efficient. Its low maintenance requirements also make it an ideal choice for industries that require maximum uptime and reliability.
Coupling make-up machines, mainly used in casing & tubing production factory and threads repairy shop.
Pipe end reducing machine, is a machine used for reduce the pipe end diamaters so as to cut premium threads. the clamping head can apply pressure to the pipe end to compress the pipe port, enables the shrinkage of the pipe end, and during the whole process of the pipe is fixed,no restriction on the shape of the pipe.
RTN-60X adopts an advanced thread geometry design to reduce thread galling: pitch change on coupling thread while pin thread maintain unchanged. This design concept avoids the high initial thread loads experieneed by conventional constant pitch threads.
The unique combination of a metal-to-metal seal and a special relief groove in coupling provides pressure integrity for both internal and external pressure in moderate to heavy wall tubular applications.
Coupling connection type, the connection strength reaches to or over that of pipe body.
Coupling design: Coupling critical cross sections are greater than those of the pipe body.
