What is a pipelayer or pipefitter?

Plumbers, of a sort. Here's some info from the U.S. Department of Labor. Most people are familiar with plumbers, who come to their home to unclog a drain or install an appliance. In addition to these activities, however, pipelayers, plumbers, pipefitters, and steamfitters install, maintain, and repair many different types of pipe systems. For example, some systems move water to a municipal water treatment plant and then to residential, commercial, and public buildings. Other systems dispose of waste, provide gas to stoves and furnaces, or supply air-conditioning. Pipe systems in powerplants carry the steam that powers huge turbines. Pipes also are used in manufacturing plants to move material through the production process. Specialized piping systems are very important in both pharmaceutical and computer-chip manufacturing. Although pipelaying, plumbing, pipefitting, and steamfitting sometimes are considered a single trade, workers generally specialize in one of the four areas. Pipelayers lay clay, concrete, plastic, or cast-iron pipe for drains, sewers, water mains, and oil or gas lines. Before laying the pipe, pipelayers prepare and grade the trenches either manually or with machines. Plumbers install and repair the water, waste disposal, drainage, and gas systems in homes and commercial and industrial buildings. Plumbers also install plumbing fixtures

How do you seal stainless steel pipe thread?

Stainless steel pipe threads are prone to leaking as well as seizing or gulling of the threads. After many years of experience and pressure testing systems up to 7700 PSI I have found this works best.

Apply UNASCO MX-68 Silver Stainless Steel Pipe Thread Sealing Tape to the threads (4-5) wraps is sufficient for smaller pipes. Generally found that covering all the threads 2 layers deep works well.

Step 2

On top of the Teflon apply a layer of SWAK thread sealing compound. Be sure to cover all around the pipe from the starting thread to the half way point of the entire length of thread.

Can copper and galvanized pipes be used on the same fitting?

Yes and no. Pipes are pipes and many houses have both copper and galvinized. But copper and galvinized pipe must never come into direct contact with each other. You have to put what's called a dielectric fitting (available at your local hardware store) in between them. The problem is that without a dielectric fitting you'll get what's called electrolysis. Electrolysis eats holes in your pipes. Like I said, just put in a dielectric fitting. No sweat.

What is a cut-sheet?

A cut sheet is a general term for a few pages of specifications, instructions, dimensions, etc. that apply to a certain technical product or product line, generally shipped with the product. It is my understanding that they are called such because they are frequently pages which are "cut" from the company catalog.

Cut sheets are generally specific enough to convey any information that the customer might need to install or use the product.
