a In case of dispute, laboratory Rockwell C hardness testing shall be used as the referee method.
b No hardness limits are specified, but the maximum variation is restricted as a manufacturing control in accordance with 7.8 and 7.9.
c For through-wall hardness tests of Grades L80 (all types), C90, T95 and C110, the requirements stated in HRC scale are for maximum mean hardness number.

One of the key advantages of seamless steel pipes is their ability to handle high pressure. These pipes are manufactured without any seams or joints, which makes them highly resistant to leaks and bursting. This makes them ideal for industries that require the transportation of fluids or gases under high pressure, such as the Oil and gas industry. casing Pipe,casing well pipe, casing supreme pipe, casing vs carrier pipe, casing for ac pipe, casing steel pipe, casing pipe size, casing pvc pipe price, casing pipe, casing pipe suppliers in China, casing capping pipe, casing drill pipe,carrier pipe,casing pipe size,bushing Flange,bushing sleeve,bushing,bushing arm,bushing bearing,bushing Reducer,bushing tool,bushing pvc,bushing meaning

Another advantage of seamless steel pipes is their ability to withstand high temperatures. These pipes are made from high-quality steel that can withstand extreme heat without deforming or losing their structural integrity. This makes them suitable for industries that involve high-temperature processes, such as power generation and chemical manufacturing.

Seamless steel pipes are also known for their durability. The absence of seams or joints eliminates weak points in the pipe, making it less prone to corrosion and damage. This durability makes them ideal for industries that require long-lasting and reliable piping systems, such as construction and infrastructure.

In addition to their durability, seamless steel pipes offer excellent resistance to corrosion. The smooth surface of these pipes prevents the accumulation of rust and other corrosive materials, ensuring a longer lifespan and reduced maintenance costs. This makes them a preferred choice for industries that deal with corrosive substances, such as the chemical and petrochemical industry. Furthermore, seamless steel pipes offer superior strength compared to other types of pipes. The absence of seams or joints eliminates the risk of weak points, making these pipes highly resistant to external forces and pressure. This strength makes them suitable for industries that require robust piping systems, such as mining and offshore drilling. Seamless steel pipes also provide excellent dimensional accuracy. The manufacturing process of these pipes ensures precise measurements and consistent wall thickness, resulting in a uniform and reliable product. This dimensional accuracy is crucial for industries that require precise and efficient flow of fluids or gases, such as the pharmaceutical and food processing industry.

Moreover, seamless steel pipes offer a smooth internal surface, which reduces friction and pressure loss during fluid or gas transportation. This smoothness allows for efficient flow and minimizes energy consumption, making them an energy-efficient choice for industries that prioritize sustainability and cost-effectiveness. In conclusion, seamless steel pipes offer numerous advantages in various industries. Their ability to handle high pressure and temperature, along with their durability, resistance to corrosion, and
