In our ordinary life, we will find steel pipes everywhere. Thin-walled welded pipes such as tap water use steel pipes, natural gas transportation use steel pipes, and thin-walled welded pipe bicycle brackets also use steel pipes. So is there a kind of steel pipe can be used in all aspects? In fact, there is really this kind of steel pipe, that is straight seam welded pipe. So the emergence of straight seam welded pipe is really a revolution in the history of steel pipe. So why does the straight seam welded pipe have so many functions? In normal life, we can see that there are many pipeline systems. Except for some special pipes, most of the pipes are made of steel pipes. However, steel pipes exposed to the outside will easily rust.

Many people doubt the corrosion resistance of 3pe elbow anticorrosive steel pipe and 2pe elbow anticorrosive steel pipe. As long as you understand the manufacturing technology of 3pe elbow anticorrosive steel pipe and 2pe elbow anticorrosive steel pipe, you will understand that 3pe elbow anticorrosive steel pipe and 2pe elbow anticorrosive steel pipe have the same corrosion resistance as ordinary anticorrosive steel pipe. The 3pe elbow anti-corrosion steel pipe looks messy because the anti-corrosion of both ends on specific equipment. And the equipment is unable to meet the construction of the elbow. Generally speaking, only straight pipes are required to end construction on the equipment. About 3PE or 2PE anti-corrosion of elbow pipe, the general solution is as follows:

Steel plastic composite pipe is made of steel and plastic material composite pipe, also known as lined composite pipe galvanized steel pipe. To the steel plastic composite pipe is divided into two kinds of cold water pipe and hot water pipe. Due to the special manufacturing technology of steel pipes, pay attention to several aspects during use, which can well protect the life of steel-plastic composite pipes. So, the following to understand the steel plastic composite pipe construction matters needing attention.

With the application of polyurethane insulation steel pipe more and more widely, many fake polyurethane insulation steel pipe began to flow to the market, in order to avoid the purchase of fake polyurethane insulation pipe, introduce how to identify the quality of polyurethane insulation steel pipe.

Anticorrosive steel pipe surface mirror bright treatment method: according to the complexity of anticorrosive steel pipe products and user requirements can be used respectively mechanical polishing, chemical polishing, electrochemical polishing and other methods to achieve mirror gloss. Anticorrosive steel pipe coloring methods are as follows:
