Tube Pulling & Removal
As the tubes of boilers, heat exchangers and condensers corrode and suffer damage from long-term use the tubes need to be periodically replaced. Tube Pulling systems (tube pullers) are designed for this task. Using Hydraulic power they break the seal and pull expanded tubes from the tube sheets. (or Boiler Plates).
Typically this is done by driving a mandrel (also called a spear) into the tube inner diameter. A hydraulic ram with special attachments (also called a tube pulling gun) is loaded over the mandrel and grips hold of it. As the ram extends it applies force to the mandrel which then acts to pull on the tube in order to extract it
The hydraulic pump can be, electrically or pneumatically driven. The pulling force required varies with the tube size and wall thickness, the depth of the tube sheet and tube material. Stub pullers are also available to be used where tubes are cut behind the tube sheet leaving only the short tube ‘stubs’ to be removed.
The Javelin is a compact and dependable tube pulling (puller) machine and is designed for continuous and stub removal of tubes from heat exchangers, condensers and boilers. A fully tried and tested system that can be used where access is tight, this does not however compromise power of pulling capacity.
The Trident Tube Puller is a fast and dependable automatic tube pulling machine and is designed for continuous and stub removal of tubes from heat exchangers, condensers and boilers. We off the Trident Tube Puller with an Electric Powerpack or a fully Pneumatic Powerpack.
