Abstract
A mobile factory of steel sheet coil helical pipe includes a factory for the production of helical pipes that can be mounted on trailers, rafts, or container-type structures that is distinguished by its high production speed and use of steel sheet coils of up to 1″ possible thanks to the use of an optional coil driver, a beveler and a wire welding system that may contain two, three, four, or five welding wires per pass (internal and external).
Claims9
A mobile factory for production of a helical pipe from steel sheet coils using equipment mounted on an autonomous low trailer, raft, or container, the mobile factory comprising:
- an unwinder configured to receive a steel sheet coil;
- at least one press;
- a first drive puller and a second drive puller configured to move the steel sheet along a production line;
- a calander;
- guide tables configured to maintain an alignment of the steel sheet in a direction of the calander;
- a third drive puller positioned between the second drive puller and a guide table, of the guide tables, preceding the calander;
- a welding machine comprising a wire welding system;
- a pipe straightener;
- and
- a beveler configured to make chamfers ranging from 15° to 30° on side edges of the steel sheet;
- wherein the pipe straightener and beveler are positioned preceding the calander and the welding machine.
