Definitions

• This invention relates to pipe parts, such as curves, angles, T joints, reducing parts, etc., included in a weldable piping system.
• the manufacture of pipings generally involves the problem of fitting pipes and pipe parts into corners while aligning the pipes with a water level, followed by joining the pipes by welding.
• the object of the invention is to eliminate the shortcoming mentioned above.
• the piping system in accordance with the invention is characterised by the fact that the ends of the pipe parts are provided with angular marks, such as 90° or 45° graduated lines. Narious embodiments of the invention are described in the dependent claims of the set of claims.
• the angular marks of the invention facilitate the fitting of pipes and pipe parts.
• the need for water levels is almost totally eliminated. Installation becomes appreciably more rapid and degree errors between pipes and pipe parts are minimised.
• the plumber will have both his hands free to direct and weld the parts to be mounted.
• the indication of a curve break also speeds up pipe installation, because unnecessary measurements and marks are thus eliminated.
• figure 1 illustrates a straight pipe provided with line marks
• figure 2 shows a pipe curve
• figure 3 shows a T joint
• figure 4 shows a pipe cone
• figure 5 shows the end of a pipe called "black pipe”.
• the ends of pipe 1 and the pipe parts, curve 2, T joint 3 and pipe reduction 4 are provided with painted, 90° and 45° graduated angular marks.
• the conical surface 7 of the end of the "black pipe” 6 in figure 5 is provided with marks 8, which are milled lines.
• the 90° graduated marks are painted more visible and longer than the 45° graduated marks.
• Curve 2 in figure 2 is equipped with a break line 9 encircling the curve at 45°.
• the pipe parts may be otherwise graduated, as for instance 15°, 30°, 45°, 60° etc., or even at smaller intervals, depending on the purpose of use of the pipes and the pipe parts.
