The inspection and inspection of the quality of the billet and the necessary cleaning of the surface defects of the billet are the basic prerequisites to ensure that the blanks used in the production of seamless steel pipes meet the quality requirements.

There are many ways to link steel pipes (such as seamless pipes and welded steel pipes), and the commonly used ones are:Compression type, union type, compression type, pusher type, taper thread type, socket welding type, union type flange connection, welding type and derivative series connection methods combining welding and traditional connection.

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.
