Black Steel Pipe For Hydraulics is also called carbon steel pipe because it is made of carbon steel that has been treated with black oxidation. Black steel pipe for hydraulics is used in many industries and applications, from robotics to construction. Hydraulic pipes are an important part of any hydraulic system because they carry fluid from one point to another.
Black steel pipes are easier to clean and more hygienic.The black oxide coating also makes it easy to clean and resistant to corrosion and wear.It is a highly durable metal that is widely used in hydraulic and plumbing applications because of its strength and durability.| Steel Grade | Chemical Components (%) | ||||||
