Carbon steel seamless steel pipe is a long strip of steel. Steel pipe has a hollow cross-section, and a large number of used for conveying fluid pipelines, such as conveying oil, natural gas, gas, water, and some solid materials pipelines. Compared with solid steel such as round steel, steel pipe has the same bending and torsional strength and is light in weight. It is an economic cross-section steel, widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automobile drive shafts, bicycle frames, steel scaffolding used in construction, etc.

In the project construction, we choose carbon steel seamless steel pipe, should pay attention to what matters, let's say respectively.

(1) Building structure heavy industrial building structures, large span structures, high-rise or super high-rise civil building structures, or structure and other important structures should consider the selection of good quality seamless steel pipe, for general industrial and civil building structures, which can be selected according to the nature of the work of ordinary quality seamless steel pipe.

(2) the structure directly bearing the dynamic load and the structure in the strong earthquake area should choose seamless steel pipe with good comprehensive performance; Generally under the static load of the structure can choose the lower price of seamless steel pipe.

(3) The welding process of the connection method will produce welding deformation, welding stress, and other welding defects, which may lead to cracks or brittle fractures of the structure. Therefore, the welding structure of the material requirements should be strict.

(4) The temperature and environment of the building structure, seamless steel tube is easy to cold brittle at low temperature, so the structure working at low temperature, especially the welding structure, should be selected with the good low-temperature brittle performance of the calm steel. In addition, the open structure of the Taiyuan seamless steel tube is easy to produce aging, and the harmful medium of the seamless steel tube is easy to corrosion, fatigue, and fracture, so different materials should be selected.

(5) the thickness of the seamless steel tube is thin and the rolling frequency of the seamless steel tube is more, the compression ratio of the rolling is large, and the compression ratio of the thick seamless steel tube is small, so the thickness of the precision steel tube is not only small strength but also poor plasticity, impact toughness, and welding performance. Therefore, the welded structure with large thickness should adopt the seamless steel pipe with better material.

Cangzhou Shenlong Pipe Manufacturing Co., Ltd. cooperates with Baosteel and Baogang to produce large-caliber seamless steel pipe, straight-seam welded pipe, spiral steel pipe, and pipe fittings. The products comply with API, ASTM, DIN, BS, and JIS standards, and can accept SGS, BV, and other inspections. The products are used in oil, natural gas, bridge, water conservancy, and other large-scale projects, which are worthy of trust.
