Pressure Vessel Clamps

Download Data Sheet in PDF Format: 

Alchem Process Ltd now offer a range of pressure vessel clamps with both Flat Grip and Round Grip claw options.


Designed to be used with pressure vessels and tanks, pipelines, reactor vessels and autoclaves.  The clamps use hexagonal bolts and nuts as standard to close and secure the assembly into position, along machined grooves.


The clamps offer a quick release alternative to conventional bolting systems and avoid the need for the vessel closure to be flanged and drilled.  This allows the vessel to be smaller in diameter and also reduces the amount of material used and time taken to assemble and dismantle.


The bolt sizes range from M10 to M56

  • Carbon steel to ASTM A193 Gr B7
