This invention discloses a descaling apparatus for steel tubes of the building scaffold, belonging to the technical field of construction equipment, which solves the existing problems with low quality in rust-removal of the steel tube of the building scaffold, and the descaling apparatus for steel tubes of the building scaffold comprises a bottom panel (1), a working table (11), a pushing base (2) on the bottom panel (1) along a length direction, several of forward rust-scraping rings (3) and several of reverse rust-scraping rings (4) on the working table (11), several of forward scrapers (33) on the forward rust-scraping rings (3), several of reverse scrapers (43) on the reverse rust-scraping rings (4), a driving member on the working table (11), several sets of rolling assemblies (5) on the working table (11); this invention has a better rust-removal effect and is more labor-saving when in manual operation.

A cold-weld burr removal system is disclosed according to various embodiments. The cold-weld burr removal system can include a clamping block having a clamping passage that extends along an alignment axis, and a removal block having a guide passage alignment axis centered about the alignment axis. The removal block can define a burr receiving chamber. The system also can include a cutting head insert having a cutting portion and a cutting passage. The cutting head insert can removably attach to the removal block and the cutting portion can protrude into the burr receiving chamber. The system can include a linear actuator that connects the clamping block to the removal block. The linear actuator can move the removal block in a direction along the alignment axis to increase a separation distance between the clamping block and the removal block when a linear actuation initiator initiates movement of the linear actuator.

There is provided a pipe peeler for removing a layer of material from an outer surface of a pipe. The pipe peeler includes a split housing for releasably mounting around the outer surface of the pipe, and three or more rollers rotatably secured to the housing. Each of the rollers has a contact surface that extends into a central opening for rotational contact with the pipe. Each of the rollers are positioned in the same plane, wherein the plane of the rollers is oriented perpendicular to a longitudinal axis of the split housing The pipe peeler includes a cutting blade, secured to an arm for mounting to the split housing, and a handle extending from the split housing for manually rotating the cutting blade about the outer surface of the pipe. Rotational contact between the rollers and the pipe stabilizes the pipe within the central opening.
