'<br>So what does it mean when a company asks "2 Black Pipe Fittings"? That depends on whom you ask. A company that installs gas, commercial, or electric pipeline may refer to it that way or may describe it as a specially designed system. Regardless of the terminology used, the quality of the products installed is the same and should be considered during any inspection of the systems.<br><br><br>"Why do we need 2 black pipe fittings?" A. Almost all types of pipeline and fittings are inspected to make sure that they meet certain pressure and temperature requirements. These specifications are based on federal, state, and local regulations. When pipelines and fittings aren't up to code, the result can be catastrophic.<br><br><br>"How do we cut a cast iron tee?" B. A cast-iron tee, also known as a cold disc, requires precise pre-drilling before installation. It is very common for companies to try to install the tee by drilling straight into it at the pre-drilled position, but this often causes severe damages that lead to complete replacement of the unit. If you choose to drill your own pre-drilled tee, always make sure you use a drill bit that is the correct diameter for the size of your gas or oil pipelines.<br><br><br>"How do we install 2 black pipe fittings, using raw material?" C. Most pipeline installations today use high quality cold rolled steel. This raw material must be carefully prepared before installation in order for it to resist corrosion from the natural elements such as moisture, heat, and exposure to the sun. The resins in the new HDPE material must also be specially treated to resist damage caused by salt spray or chlorination.<br><br><br>"How do we cut a cast iron tee with raw material?" D. You must carefully measure the area you will be working on so that you have accurate measurements to work with when making your calculations for the heat that will be generated with each pump stroke. Use a hydraulic press to press your rough measurements into the raw material and begin to cut it with your electric cutting tool. Do not cut too much as you may create too large a hole and disturb the natural flow of the material, or else, you will find yourself having to drill the new holes again.<br><br><br>"How do we cut a 2 inch npt pipe with raw material?" E. The easiest way to cut a 2 inch npt pipe is to make use of a utility knife. First, make a very deep incision about one third of an inch long (the pipe will be one inch long in diameter) then insert a straightened stainless steel or other metal tube (at least one end should be securely fastened into the ground) into this incision. Next, using a hydraulic press you should slice this tube straight down into the core. Use the same measurement that you used to take out the original raw material.<br><br><br>"How do we cut a half-inch copper tee with malleable iron fittings?" F. There are basically two different ways in which to perform this operation. You can either make use of a hacksaw or a table saw to do the job. The method you use will depend on the diameter of the tee you will be cutting, and the distance between the ends of the fitting.<br><br><br>These two classes of materials consist of: Class 150 iron pipe, and Class 8. 1984 copper tubes. This information on pipes comes from the US Bureau of Labor Statistics, and their website at the BLS.
