Sir,
Customer gets what he pays for;'quality' is also factored in it. In Wal-Mart, don't you pay for the smile of the sales person, too ?

So, if a client replicates 15 MW unit Biomass based power plant for 3 identical twin-unit captive power stations in his own cement plant hoping for Climate Change CDM benefits, he gets the quality of the order you write for the reference plant design of steam piping. But, the same analyst gives an over-simplified print-out for a much serious service handling flammable fluid, if the deal needs up to that detail only. If client pays more, he can get more,too.

Moreover, to take credit for value addition, today's front-end smarts define small bore pipe thickness at sch 40, while raising corrosion allowance from 1.0 mm to 3.5 mm, retaining the original specification's design pr/temp & piping thickness. Everything is possible in Harry Potter's age, why to blame us, the piping analysts only , why don't we go to sufficient detail, when such situation arises ?

regards,
sam
