ASTM A36 steel is a common structural steel that can be used in many fields. It is a mild steel with good strength, formability and excellent weldability. Due to its characteristics, this steel plate is widely used in many fields such as construction, agriculture, and automobiles. ASTM A36 steel plates can also be used in other applications such as bolts, nails, screws and other fasteners.

Steel plate is a flat steel made of molten steel after being rolled or cut. Because of its excellent performance and diversified uses, it is widely used in construction, manufacturing and various industrial fields.

Because of its excellent mechanical properties and corrosion resistance, seamless steel pipes are widely used in construction, chemical industry and other industries. However, in the process of use, cracking problems occasionally occur, not only causing material waste, but also increasing the cost and project delay risk.

Seamless steel pipe is a kind of thin steel with hollow cross-section and no joints around. They are widely used in a variety of industries, mainly for fluid transport, including the transport of oil, natural gas, natural gas, water and certain solid materials. Compared with solid steel materials such as round rods, seamless steel pipes are lighter in weight while maintaining similar yield strength and tensile strength, making them economically viable structural and mechanical components. They are commonly used in the manufacture of structural elements and mechanical components such as oil drill pipe, car drive shafts, bicycle frames and steel scaffolding used in construction.

Stainless welded steel pipe will have a certain degree of deformation in the use or production process. This situation is influenced by many factors.

Stainless welded steel pipe can be seen everywhere in our daily life, such as handrails, railings and so on. Among them, stainless steel welded pipes are also often used in the construction industry and industry. The production process of stainless welded steel pipe is more complex, and there are strict requirements for production technology. Stainless welded steel pipes have strong stability and corrosion resistance, and different stainless welded steel pipes have different functions.

A106 and A53 are the most commonly used carbon steel pipe types in industry today, and they are very similar. However, there are some differences in material, production process, application and so on. Although the gap between them is very small, they are irreplaceable in certain aspects.

In addition to different materials, pipes come in a variety of sizes, classified according to specifications, and SCH40 steel pipe is one of the most commonly used materials in a variety of building and construction applications. With moderate strength, durability and low cost, it is suitable for applications with moderate pressures and temperatures.

Straight seam steel pipe and spiral steel pipe are two common types of welded steel pipe, they are different in the production process, structural characteristics, application fields and so on.

ASTM A106 Gr.B A seamless carbon steel pipe material in line with ASTM standards, the steel pipe made of this material is specially used for transportation under various high temperature and high pressure environments, often used in oil, natural gas, chemical, electric power and other industries, for conveying high temperature water, gas, oil and so on.

Welded steel pipe is a welded steel pipe, and the production process is to bend the steel plate or steel strip into the tube blank with the required section shape and size by various methods, and then weld the weld with different welding methods to obtain the process of steel pipe.

ASTM A53 GR B Seamless Carbon Steel Pipe refers to seamless carbon steel pipes that meet the standards set out in ASTM A53. Among the specifications covered by ASTM A53 GR B pipes are seamless and black welded pipes and hot-dip galvanized steel pipes with NPS sizes ranging from 1-8 to 26. ASTM A53 GR B seamless carbon steel pipe is a medium-carbon steel pipe with a carbon content of 0.3% and a manganese content of 1.2%. This type of pipe is widely used in various industries due to its strength, durability, and pressure resistance.

Hot rolling process is a metal processing method, mainly used to heat metal to a certain high temperature and plastic deformation through tools such as rollers to achieve the desired shape and size. The hot rolling process is commonly used in steel production and is suitable for most metal materials, especially steel. During the hot rolling process, the metal is heated above the recrystallization temperature (usually between 1000°C and 1300°C), so that the metal's grains rearrange and become more uniform, enhancing its malleability and plasticity.

In the production process of seamless steel pipe, the problem of surface defects often occurs, which is closely related to its material, production process, processing environment and other factors.
