Abstract
A coating lance includes a body having first and second segments interconnected in a joint region. The first segment, which can be made from metal, includes an outer diameter reducing from a first outer diameter in a rearward portion through a transition portion to a second outer diameter in a main segment portion. The second body segment, which can be made from carbon fiber, is substantially uniform in outer diameter throughout. A coating tube extends within an interior of the body and a nozzle end part is attached to the coating tube. The lance can also include an insert received in a discharge end of the body, a discharge end clamp secured to the insert, and a charge end clamp secured to a charging end of the body. The clamps receive the coating tube and apply a clamping force to secure the coating tube in position.
Claims19
A coating lance for applying a coating material in spray form, the coating lance comprising:
- a first elongated tubular body segment;
- and
- a second elongated tubular body segment, the first and second body segments interconnected at a joint region to form a lance body, the first and second body segments made from dissimilar materials,
- wherein the material for the first body segment of the lance body is stainless steel and the material for the second body segment is carbon fiber.
A coating lance for applying a coating spray onto a surface, the coating lance comprising:
- a tubular lance body defining an interior space and opposite charging and discharging ends, the lance body having first and second segments respectively defining the charging and discharging ends and interconnected to each other in an intermediate joint region, the first and second segments made from dissimilar materials;
- a coating tube housed within the interior space of the lance body to extend between the charging and discharging ends to convey a coating material through the lance body;
- and
- a nozzle end part attached to a discharge end of the coating tube, the nozzle end part being tubular and having inner and outer dimensions substantially matching inner and outer dimensions of the coating tube, the nozzle end part attached to the coating tube by welding,
- wherein the material for the first body segment of the lance body is stainless steel and the material for the second body segment is carbon fiber.
A hybrid coating lance comprising:
- an elongated tubular lance body defining an interior space and having first and second body segments interconnected with each other in a joint region, the first body segment made from a metal and the second body segment made from carbon fiber, the first metal segment including first, second and third portions, the first portion defining a charging end of the lance body and having a first outer body diameter, the second portion located forwardly of the first portion and having an outer diameter that transitions from the first outer body diameter to a second outer body diameter that is less than the first outer body diameter, the third portion located forwardly of the second portion and having an outer diameter that is substantially equal to the second outer body diameter, the second carbon fiber body segment defining a discharging end of the lance body and having an outer diameter that is substantially constant throughout a length of the body segment;
- a coating tube housed within the interior space of the lance body to convey a coating material between the charging and discharging ends of the lance body;
- and
- a tubular nozzle end part attached to coating tube adjacent the discharging end of the lance body, the nozzle end part having inner and outer dimensions substantially matching inner and outer dimensions of the coating tube, the nozzle end part attached to the coating tube by welding.
