Types of carbon steel pipe
Carbon steel can be divided into two types due to their structure: general carbon steel and high-quality carbon steel. The first one contains more impurities and is inexpensive.
It is used where performance requirements are not high. The carbon content is mostly below 0.30%, and the manganese content does not exceed 0.80%. It has low strength but has toughness, deformation, and plasticity properties. Except in a few cases, it is generally used directly without heat treatment.
Carbon steel pipe construction and materials
First of all, construction preparation, an inspection of materials, equipment, and products. Then the production and installation of pipe supports, fasteners, etc., colleagues for pipe processing, prefabrication. Then the installation of piping and accessories. Then the system is tested, purged, or cleaned. Finally, anti-corrosion insulation.
Carbon steel pipe vs Black steel pipe
Black steel pipes are uncoated steel pipes. The dark surface is due to the iron oxide formed on the surface during the production process.
The main purpose of black steel pipes is to transport propane or natural gas to residential and commercial buildings. The black pipe is a seamless steel pipe, which makes the gas more convenient to transport and not easy to leak. Black steel pipe is also used in fire sprinkler systems because it is more resistant to fire than a carbon steel pipe.
|carbon steel pipe||black steel pipe|
|Carbon steel is steel with carbon as the main component.||The black steel is not galvanized and has a dark iron oxide coating on the surface.|
|The hardness of carbon steel pipe depends on the carbon content.||Black steel pipe has high strength and high hardness.|
|Carbon steel pipes are easily corroded, so galvanizing is required.||Not required.|
