Introduction of galvanized interlock pipe

The galvanized interlock pipe has a wide range of uses, except for line pipes for conveying water, gas, oil, and other general low-pressure fluids. The galvanized interlock pipe is also used in the petroleum industry, especially for oil well pipes and oil pipelines in offshore oil fields, oil heaters, condensing coolers, coal distillate wash oil exchanger pipes for chemical coking equipment, and support frames for trestle pipe piles and mine tunnels Tube and so on. Next, let’s take a look at the introduction of galvanized interlock pipe. Here are some answers.

Use of galvanized interlock pipe.

Galvanized interlock pipes are mostly used in old houses, and the iron pipes used for gas and heating are also galvanized interlock pipes. The galvanized interlock pipe is used as a water pipe. After several years of use, a large amount of rust will be generated in the galvanized interlock pipe. The yellow water that flows out not only contaminates the sanitary ware but also contains bacteria that breed on the uneven inner wall. The rust causes the heavy metal content in the water to be too high, which seriously harms the human body's health.

Derusting method of galvanized interlock pipe.

First, use a solvent to clean the surface of the galvanized interlock pipe to remove the organic matter on the surface. Then use tools to remove rust (wire brush) to remove loose or inclined scales, rust, welding slag, etc. The galvanized interlock pipe is divided into hot galvanized interlock pipe and cold galvanized interlock pipe. Hot galvanized interlock pipe is not easy to rust, and cold galvanized interlock pipe is easy to rust.

Welded connection of galvanized interlock pipe.

First, the galvanized interlock pipe nozzles are not in a straight line and the steel galvanized interlock pipe has an oblique joint after butting. It is recommended to cut off the galvanized interlock pipe head for a short period before processing.

Second, after the galvanized interlock pipe nozzles are butted, the two nozzles are not tightly connected, resulting in an uneven thickness of the weld; and the galvanized interlock pipe has an oval nozzle due to its reasons or transportation bumps. It is recommended to cut the galvanized interlock pipe head. After a short period, the processing is performed.

Third, after the galvanized interlock pipe nozzles are butted, the blisters appearing at the nozzles are due to technical reasons during welding.

Fourth, the galvanized interlock pipe has zinc nodules at the mouth of the galvanized interlock pipe, which can cause welding difficulties and blisters. If the zinc nodules are too large and too many pipes, simple zinc nodules are removed.
