Black steel pipe is widely used; plastic pipe is gradually replaced by it. But what makes it so popular and what are the advantages of black steel pipe over plastic pipe? The primary purpose of black steel pipe is to carry propane or natural gas to residents. They are manufactured without a seam, making it better to carry gas. They are also used for fire sprinkler systems because it is more fire-resistant than plastic pipes. Usually, steel pipe is installed for arduous industrial purposes therefore its quality must meet the working standard. They are made to resist high pressure from internal and external. In order to achieve such purpose, they are made from high quality steel and assemble with great care.
Black steel pipes are popular because its advantages. The high tensile strength of steel and its flexibility, ductility and freedom from fragility enable steel pipes to be used for the highest pressures and under many heavy tasks. Black steel pipes are particularly able to accommodate stresses, misalignment and temperature variation. Their inherent reserves of strength can withstand stresses from severe bending, while pipes of other materials like plastic cannot resist and often break and fall. They also have high resistance to shock or vibration. Wherever fluctuating pressures, or shock pressures arise, the high strength and absence of fragility in steel pipes offer obvious advantages. Modern traffic conditions impose ever-increasing stresses on roadway foundations. For example, for pipes that buries under railway, they must need to resist high pressure from rail above and avoid burst. Black steel pipes have significant advantage over those made of plastic. They are unbreakable in transport and in service. Under a certain pressure, steel pipes can be made much thinner than plastic pipes. Consequently they have a greater carrying capacity than with the same outside diameter.
Despite the many benefits of PVC pipes, this type of piping is giving away to steel pipe because the disadvantages associated with it. First, PVC pipes are not very fire resistant; they are apt to melt at only about one hundred degree. Second is their size. They are only available in small sizes and the joints are very bulky which make it restrict to certain situation. One of the most notable reasons that PVC pipes are no longer popular is that they are more subject to cracking. Compared with steel pipes, their strength is much lower. The gradual replacement of PVC pipes is also because environmental factor. They contain compounds that are harmful to the environment so many companies do not choose to use PVC pipes.
There are the conceivable advantages of black steel pipe that make it popular. With the development of manufacturing technique and new requirement keep changing, the quality of the black steel pipe can be different and improved. There are now many customized steel pipes to meet different standard and satisfy unique demand. With all these advantages that over other pipes of material, black steel pipe will keep widely used. The welded steel pipe and API steel pipe are also available.
