Application |
The transportation of fluids, construction of buildings, and pipelines for oil are all critical industries that play a significant role in the economy. These sectors require extensive planning and investment to ensure that they meet safety and environmental standards while providing reliable and efficient services to customers. Oil pipelines are the primary mode of transportation for crude oil and other hydrocarbons, connecting production sites to refineries and distribution centers. On the other hand, fluid transportation systems facilitate the movement of various liquids, including water, chemicals, and petroleum products. Finally, the construction sector involves the design and erection of buildings, bridges, roads, and other infrastructure necessary for economic development and growth. These industries work together to drive economic development and create jobs, making them essential components of any thriving economy. |

Production Process
The production process of thick wall stainless steel seamless tubes can be classified into two main methods: cold drawing and hot rolling. Cold-rolled seamless steel pipes undergo a more intricate production process compared to hot rolling. Initially, the billet is subjected to three-roll continuous rolling and then undergoes diameter testing after extrusion. It is essential to inspect the surface for any cracks or abnormalities.
Subsequently, a cutting machine is employed to cut the round pipe into approximately one-meter-long billets. These billets then proceed to the annealing process. As part of the annealing, the steel pipes should undergo pickling using an acidic liquid. During the pickling process, special attention should be paid to the presence of excessive bubbles on the surface. If a significant number of bubbles are observed, it indicates that the steel pipe does not meet quality standards.
In terms of appearance, cold-rolled seamless steel pipes appear shorter and have smaller wall thickness compared to hot-rolled counterparts. However, they exhibit a brighter surface finish and are less rough. Additionally, the caliber of cold-rolled pipes tends to have fewer burrs.
Application Areas
* Oil pipelines must use this thick wall stainless steel pipe as a means of transportation. Because of its high quality, oil spills do not occur. Thick-walled seamless pipes are a necessary material tool for many oil companies.
* Structural stainless steel pipes (GB/T14975-2002) are seamless steel pipes for general structures and mechanical structures.
* Stainless steel seamless steel pipe for fluid transportation (GB/T14976-2002) is a general seamless steel pipe used to transport fluids such as water, oil and gas. It is usually a hot-rolled (extrusion, expansion) and cold-drawn (rolled) seamless steel pipe made of stainless steel.
* This kind of steel pipe will be used in construction. For example, in the northern region, the terrain is flat and the machinery is developed. The medium steel pipe will be used when watering the fields. For example, these steel pipes will be used in the process of building cities. For example, when building roads, this kind of steel pipes will be used when building docks. And when providing water, the water we use, as well as the water we discharge, is done with this kind of steel pipe.
* In addition, the gas we use to send west-to-east gas is transmitted with this kind of steel pipe.
* With the utilization of high-sulfur crude oil resources and the promotion of the efficient conversion of heavy (slag) oil to obtain more light oil products such as gasoline and diesel, heavy (slag) oil hydrogenation (RHT) technology and its new combination process (RICP) with catalytic cracking (FCC) have significantly improved the yield of lightweight oil products. The general operating temperature of hydrogenation units is about 400 °C and the pressure is 10-15MPa. The conveying medium generally includes heavy oil (residue oil), various catalysts, detergents, hydrogen, waste residue (sulfide, acidic water), etc. The hydrocracking device needs to operate under high temperature, high pressure and hydrogen (high ratio H2 (H2S), H2+ oil and gas (H2S)) corrosion media. H+, HS- and S2- will be ionized in aqueous solution. The corrosion of stainless steel is a hydrogen depolarization process. It is easy to cause hydrogen-induced cracking (HIC), sulfide application corrosion cracking (SSCC) and electrochemical corrosion. It is also accompanied by many changes in conditions such as CO2, NH4+ and CN-content and PH value, resulting in tube rupture failure. Therefore, UNSTP347 stainless steel pipes used in high-temperature, high-pressure and hydrogen-critical environments need to have good mechanical properties and corrosion resistance.
