ASTM A106 grade seamless steel pipe is a widely used low carbon steel and is widely used in the petroleum, chemical and boiler industries. The material has good mechanical properties.
DIN 1629 seamless steel pipe has three main grades of St37.0, St44.0, St52.0. Generally, the DIN 1629 standard is not limited to the working pressure value, and the working temperature is limited to below 300 ℃.
A252 Seamless&Welded Pipe Piles
ASTM A252 is the standard specification for nominal-wall cylindrical steel pipe piles, where the cylinder acts as a permanent load-bearing member or shell to form a cast-in-place concrete pile. The ASTM A252 specification has three grades: Grade 1, Grade 2, and Grade 3, of which Grade 2 and Grade 3 are commonly used materials.
A179 seamless cold drawn low carbon steel pipe is equivalent to China's No. 10 high-quality low-carbon steel. A179 is suitable for cold-drawn high-quality low-carbon seamless steel pipes for heat exchangers and condensers.
Mild steel tube is one of the most commonly used construction materials. It is versatile and has a wide range of applications in infrastructure projects. It is strong, durable, and lightweight. Mild steel tubes create structures such as towers, bridges, and buildings.
API Spec 5L is an international standard that specifies the manufacturing requirements for two product specification grades (PSL 1 and PSL 2) of seamless and welded steel pipes used in pipeline transportation systems in the oil and gas industry.
Shaped seamless steel pipe is a general term for seamless steel pipes with cross-sectional shapes other than round pipes. According to the different shape and size of the steel pipe section, it can be divided into equal wall thickness special-shaped seamless steel pipe (code D), unequal wall thickness special-shaped seamless steel pipe (code BD), and variable diameter special-shaped seamless steel pipe (code BJ). It is an economic section steel pipe. Including non-circular cross-sectional contours, uniform wall thickness, variable wall thickness, variable diameter and variable wall thickness along the length, symmetrical and asymmetrical cross-sections, etc. Such as square, rectangle, cone, trapezoid, spiral, etc. Special-shaped steel pipes can better adapt to the particularity of use conditions, save metal and improve the labor productivity of parts manufacturing. Shaped steel pipes are divided into different shapes according to their shapes: outer hexagonal inner round steel pipe, outer inner hexagonal steel pipe, inner and outer hexagonal steel pipe, flat oval steel pipe, oval steel pipe, triangular pipe, L-shaped steel pipe, octagonal pipe, mushroom-shaped pipe, bread-shaped pipe, D-shaped Pipes, concave pipes, convex pipes, umbrella pipes, P-shaped pipes, ingot-shaped pipes and other special-shaped steel pipes. The shape of special-shaped steel pipes is produced according to the needs of users.
Steel pipe piles and steel pipe sheet piles are widely used in ports/harbors (piers, seawalls, and breakwaters), urban civil engineering (earth-retaining walls and cofferdams), bridges (foundations for steel pipe sheet pile foundations), and other applications, along with widening their applications due to enlargement of the structures sizes, growth of water depth for the structures and increase in construction work at sites where the bearing strata are deep under thick soft ground.
Youdaoplaceholder0 Steel tube column is a composite structural component made of steel tube and concrete, which has the superior performance of both steel and concrete structures. Concrete-filled steel tube column by pouring concrete into the steel tube, the concrete inside the tube is constrained in three directions, thereby giving full play to the compressive performance of the concrete and the toughness and plasticity of the steel tube, improving the bearing capacity and seismic capacity of structural components
