After the production and cut of the pipe on the Winding System, it is transferred to the Pipe End Preparation Unit.
This is a
unit operated in conjunction and in synchronization with the pipe
production. It is composed of two
grinding stations, one at each end of the pipe and lifting
tables to hold the pipe during the grinding. These stations and the
lifting tables are placed on rails and can be adjusted in accordance with
the entry position and the length of the pipe. The lifting tables are
equipped with rollers which are adjusted to support the pipe.
Initially,
the grinding units and the rollers on the lifting tables are adjusted in
accordance with the diameter of the pipe production. When the pipe reaches
the Unit, it is received by the lifting tables, upon which rollers to
balance the pipe are installed. Then the pipe is placed and adjusted in
the grinding station. It is clamped down pneumatically between the grinder
and a roller. The grinder trims the pipe to its designed outer diameter
value and also chamfers the outer rim of the pipe for a complete match
with the coupling that will be installed.
After the
operation is completed on both ends of the pipe, the pipe is rolled back
to the Pipe Transport System.
