When we want to work as a drafter on PIPING, we should have a good background in basic drafting before pursuing a job in the field of pipe drafting and design. And because of that PIPING will explain a little about the ability what we should have, which is we should have good manual drafting skills related to line quality and freehand lettering. At the same time, students must acquire the necessary background to use the latest software tools such as AutoCAD, PROPIPE, etc, which allows them to be more productive. if we already advance, we will use a variety of sophisticated software packages, ranging from basic CAD software to 3D solid modeling.
TECHNICAL SKILLS
The drafter must become familiar with the uses of fittings, flanges, valves, and equipment. This will require time and effort to master the recognition of symbol shapes as well as research to find the dimensions needed to draw these items to scale. Often beginning drafters start out making corrections to existing drawings. This is where they acquire the skills and knowledge of piping that will allow them to advance to the position of piping designer. Drafters who have held field positions as pipe fitters or welders find this real world experience valuable. Many times this experience allows them to advance at a
faster pace.
PERSONAL SKILLS
Students should not neglect their speaking, writing, and math skills. Every company appraises future employees during the interview process, not only for technical skills, but also for the personal skills needed to interact with the engineering team. This interaction is a must for the team in order to complete the job with a minimal amount of mistakes. Honesty, reliability, dedication to improving skills, and a positive attitude contribute much to the successful career of the designer. You will be a member of a design team. You may work with people from countries all over the world. Getting along with fellow workers has much to do with successful yearly evaluations and compensation for your efforts.
Manual Drafting
Manual drafters use a variety of triangles, plastic templates (circle and ellipse), and scales to layout piping drawings. While electric erasers are not necessary, they make the job of erasing much easier and faster. Pencils and leads come in a wide range of sizes and shapes. Drafters usually use a 4H lead to draw projection linesand guidelines, and use an H or F lead for other line work and lettering needs. Line thickness also has an important role on piping drawings. A .7mm or wider lead holder is commonly used on major elements of the drawing such as pipe and lettering. Background components such as equipment, foundations, support structures, and dimension lines are typically drawn with a .5mm lead. One cannot stress enough the importance of quality line work and lettering. Manual drawings are constantly slid in and out of the file drawers and run through blueprint machines. This requires that lettering and line work
be neat and of good quality to maintain clarity of dimensions and callouts.
CAD Software Tools
There are many different CAD software tools on the market today. Many engineering companies require
their designers to know and use several different CAD software tools. Engineering companies must be prepared to accommodate the client’s preference of CAD programs. In today’s marketplace, the pipe drafter and designer should learn how to use AutoCAD and MicroStation. These two CAD programs are widely used by engineering firms in the United States and throughout the world. As with CAD programs, there are several piping software programs on the market today. Engineering firms must be responsive to the needs and preferences of their clients. Software developers steadily develop, revise, and refine programs to meet the demands of engineering and design firms. As with any business each software developer tries to incorporate the special features and amenities into their software package that will attract potential users. Often clients will dictate that all bid packages submitted for a project shall be completed using a particular piping software program. Most piping software packages provide the end user with the ability to develop three dimensional computer models of the completed facility. Software packages such as AutoPLANT, PDS, and PDMS, among others, have the intelligence to create either 2D or 3D drawings.
