Steam Heat making banging noise on pipes

Tony_28 Member Posts: 15
Hi to all, I am having this same problem, but with a little difference. I am remodeling my first home, I had to change the black pipes to my steam radiators due to change in floor plans. A friend of mine that works for heating and cooling Co re did all the steam pipes in the house, and we used black pipe. My question is I have (3) heat elements and (2) cast iron radiators, the radiators are not banging, but the heat elements are. Where the heat elements were installed, the pipe does not run straight up, but has to run across the room to get to the other side. What is the normal pitch that the pipes must have, so that the water can return to the boiler? I think I am finding my problem with you guys here. Thanks I know he pitched them, but I need to know whats the correct pitch?

    not only

    pitch but size. The experts can help, but they will need to know the size of the new elements, and the pipe diameter, and whether this is one pipe or two pipe steam.

    pipe banging noises

    The pipe size is 2inc from the the boiler, and then branches to 1 inc to the radiators. I don't know the pitch? Thanks
