Steel pipes could be classified to high frequency welded steel pipe, low pressure liquid delivery spiral submerged arc welded pipe, seam high frequency welded steel pipe by application.
Pressure fluid transport with spiral seam high frequency welded steel pipe (SY5038-83) is a hot-rolled steel strip coils for the tube, often warm spiral shape , using high frequency lap welding method , the spiral for pressurized fluid transport seam high frequency welded steel pipe . It bears strong pressure , has a good plastic, and easy welding and machining molding ; through a variety of strict and scientific inspection and testing , safe and reliable , pipe diameter , high transmission efficiency, can save the laying of pipeline investments. Mainly used for laying pipelines transport oil and natural gas.
General low pressure liquid delivery spiral submerged arc welded pipe (SY5037-83) is a hot-rolled steel strip coils for the tube, often shaped warm spiral , using double-sided automatic submerged arc welding or welding into the legal system for water, gas, air and steam and other general low pressure liquid delivery SAW pipe
General low pressure liquid delivery spiral seam high frequency welded steel pipe (SY5039-83) is a hot-rolled steel strip coils for the tube, often warm spiral shape , using high frequency lap welding method for general low pressure liquid delivery spiral submerged high frequency welded steel pipe
Pile with spiral welded steel pipe (SY5040-83) is a hot-rolled steel strip coils for the tube, often warm spiral shape , using double-sided submerged arc welding or high frequency welded for civil engineering structures , piers, bridges and other basic pile with steel pipe
Steel pipe is not only for transporting fluid and powdered solids , heat exchange , manufacturing mechanical parts and containers, it is an economic steel as well. Building structure that made with steel pipe like structural grid , pillars and mechanical support , can reduce weight, save 20 to 40 percent metal , and can realize mechanized factory construction. Using seamless pipe for building highway and bridges can not only save steel pipe , simplify construction , but also greatly reduce area that coated with a protective layer , saving investment and maintenance costs.
Intelligent Manufacturing In Steel Industry(1)
The core of German “Industry 4.0” is also intelligent manufacturing, which suit for high automation degree industry. The steel industry is one of the highest automation degree of manufacturing industries.
Intelligent Manufacturing In Steel Industry(2)
To promote "smart service " is obviously an important direction of the steel industry to achieve intelligent manufacturing .
How to classify steel pipes by application?
Steel pipes could be classified to welded steel pipe, galvanized welded steel pipe, spriral submerged arc welded pipe etc.
