Steel pipes (seamless or welded steel pipes) are used to convey fluids and powdery solids, exchange heat, manufacture mechanical parts and containers, and are also an economical steel.

SSAW pipe refers to the welded steel pipe with spiral seam welded by submerged arc welding process. Generally used in: welding into pipelines for fluid transportation, metal structures, pile foundations, etc. The feature is that it can produce welded pipes with larger diameters with narrower blanks, and it can also produce welded pipes with different diameters with the same width blanks. The production cost is low, the process is simple, and it is easy to produce large-diameter pipes.

1. Ductile ink water supply cast iron pipe:Place of use: Mainly used for the buried pipeline before the alarm valve of the automatic sprinkler system and the buried pipeline of the fire hydrant system.

The weather in summer is hot and humid. In this state, the surface of galvanized products is prone to alkali resistance (commonly known as white rust). If the plated goods are not picked up in time and unpacked and used when they arrive at the destination, it is easy to have anti-alkali phenomenon, so as to prevent irresistible losses.

The straight seam welded pipe production line is a process in which the steel plate to be welded is heated or pressurized or both are used together, and with or without filler materials, so that the material of the steel plate can be bonded between atoms to form a permanent connection.

During the welding process of the SSAW pipe, the metal material leaks to the butt weld or weld that is not heated enough, and condenses into a metal tumor. This kind of metal nodules that cannot be fused together with the butt weld or the front welding is called welding nodules.
