ข้อต่อท่อสแตนเลส (Annular Crimp) ขนาด DN20–DN50

The principle of annular crimp connection relies on the inherent rigidity of the pipe. It achieves sealing through a cylindrical filling method
using “dual-line sealing + surface sealing.” A specialized press tool is used to simultaneously compress the locking ring and sealing chamber
at the connection point, ensuring both a secure mechanical joint and a reliable seal between the pipe and fitting.

Grooved connection, also known as clamp connection, features unique flexibility. A hydraulic grooving machine
rolls a groove on the pipe end surface, which is sealed and locked by a gasket and clamp. This connection
resists vibration and thermal expansion/contraction, and is mainly used for pipelines DN65 and above.
