Abstract
A universal reusable template for cutting ends of cylindrical objects such as pipes, in preparation for joining the cylindrical objects to other cylindrical bodies. The template is formed as a flat flexible bendable sheet with magnetic properties allowing the sheet to be temporarily secured on a metal pipe. The front face of the sheet has reference indicia corresponding to contour lines of a desired cut to be made in the end of the cylindrical body. The cut lines represent most conventional types and sizes of lateral-type cuts, eccentric cuts and saddle-type cuts, with pipe diameters ranging from about 3″ to about 24″.
Claims32
A reusable template device for forming cutting contours on a cylindrical body in preparation for securing the cylindrical body with another cylindrical body, the device comprising:
- a flat sheet carrying a plurality of reference indicia defined on a front surface of the sheet, said reference indicia comprising cutting contour reference lines corresponding to a plurality of pipe diameters and angles of desired cutting, said reference indicia differing in the dimensions and contours based on a desired angle of connection between the cylindrical bodies and diameter of the cylindrical bodies to be joined.
A method of cutting a cylindrical object according to a pattern of predetermined cut in preparation of the cylindrical object being joined with another body, comprising the steps:
- providing a template in the form of a flat sheet having planar sides coextensive with a perimeter of the sheet and having reference indicia imprinted, said indicia comprising cutting contour reference lines corresponding to a plurality of pipe diameters and angles of desired cutting, said reference indicia differing in the dimensions and contours based on a desired angle of connection between the cylindrical object to another body and diameter of the cylindrical body, to which the cylindrical object is prepared to be joined;
- positioning said template over the cylindrical object;
- determining a selection criterion with respect to position of the reference line on the sheet based on a size of the cylindrical object and the cylindrical body and the angle of connection between the cylindrical object and the cylindrical body;
- and
- forming marking points in the cylindrical object by puncturing, at predetermined intervals, the sheet along the selected reference line and transferring the marking points to the cylindrical object;
- cutting the cylindrical object, while following the marking points.
A template device for cutting an end of a pipe in preparation for joining with another pipe, the device comprising:
- a flat sheet formed from a flexible material, said sheet being configured and dimensioned to correspond to the perimeter of an arcuately shaped cut end of a pipe, said sheet carrying a plurality of reference indicia defined on a front surface of the sheet, said reference indicia comprising cutting contour reference lines corresponding to a plurality of pipe diameters and angles of desired cutting, said reference indicia differing in the dimensions and contours based on a desired angle of connection between the cut pipe and a pipe to be joined, and diameter of the pipes to be joined.
