Cutting and drawing manual orbital machine of the pipe preservation system

Abstract

The present invention refers to a machine for cutting the external coating for drawing the Coated Pipe Preservation System for Onshore and Subsea Pipelines, called PPS System or PPS for short (FIGS. 1, 1.1 to 1.4). This Machine, called the Cutting and Drawing Manual Orbital Machine of the PPS (FIGS. 7 to 9), performs the cut at the angle (β) (2.4), executes the FBE Exposure Band (FBE Tail) (2.3), simultaneously, and draws the PPS System, in order to ensure that the Collar (Cutback) (2.2) meets the specifications regarding the finishing of the Chamfer (2.4) at the interface with the external coating of the pipe, its Length (C) (2.6) and the Width (T) of the FBE Exposure Band (FBE Tail) (2.7). The equipment performs cutting with the pipe being static (immovable), and is applicable to pipes externally coated in three layers (3 Layer Coating), used in Onshore Pipelines (Buried Pipelines) or Subsea Pipelines (Subsea or Submerged Pipelines). It uses the PPS System to couple to the pipe, it is demountable, portable and can be manually operated without using any power source or using a commercial screwdriver.
