Grading scheme

Bringing this to the top of the pile. 

...(y)our mark for the Pipe 0001 Pipe Trades Theory class. The overall grade will be based on assignments (30%), quizzes (30%) and final exam (40%).
Your lowest quiz mark will be excluded from the final calculation-- everyone has an off day.

The practical mark Pipe 0002 is based on a document like this.

Brass fitting blow out

What happens when you concentrate the heat too much on an alloy fitting? It is possible to melt right through the metal and wreck the fitting. In this case it is a $5 adaptor but it could be a customers thousand dollar piece of equipment. 

Why would this happen? Because piping fittings are made of brass or bronze, which are alloys of copper and other materials, mostly tin or zinc but also manganese, iron, lead, silicon, bismuth, antimony, aluminum and others. Because some of these materials have a much lower melting point than copper they melt much more easily. 

Check out the bronze and brass alloys in this chart and not the percentages of different materials and the melting points.
