The following Yan Xin Sen domain Xiaobian will introduce to you：

Old steel pipes are not classified according to wall thickness when sorting, but are classified by length, so when you buy the old pipe, you will find that although it is a six-meter old steel pipe, its thickness is uneven.
When you turn old steel pipes, you will often find that there are cement plugs at the ends of the old steel pipes of some factories. In fact, the old steel pipes will have more or less plugs, but you must be optimistic, buy less plugs, or else I bought cement at the old steel pipe price, and I was not very comfortable in my heart.
