Technical Requirements for Stainless Steel Tubes

Date:2017-07-04    keywords:stainless steel tubes
Technical requirements for stainless steel tubes are following below:

(1) Good corrosion resistance. The most basic requirements for stainless steel tube is corrosion resistance, that is, according to the use of different conditions, requiring steel pipe can withstand general corrosion, intergranular corrosion, point corrosion, stress corrosion. For the largest amount of austenitic stainless steel tube, resistance to intergranular corrosion is often the most basic requirements.
(2) Good processing performance differences. Stainless steel tube in the use of the process, most of the need for elbow, expansion and other processing, anti-corrosion steel pipe, so the steel pipe has a good flattening, flaring and other work performance.
(3) Good welding performance. Stainless steel tube for a large number of fluid pipeline, in use, anti-corrosion steel pipe welding is very large, the quality of each weld is very strict, responsible for causing a major accident.
(4) Good organization and performance stability, for long-term use at high temperatures endless steel pipe, due to the erosion of high-temperature media, oxidation, carburizing, the steel will change the organization, so the requirements of such steel should have Good organization and performance stability.
(5) Chemical composition evenly. Uneven chemical composition, will lead to uneven organization and performance of steel pipe in the entire pipe system or equipment to form a weak link or hidden danger, so the chemical composition is the most basic requirements.
(6) High dimensional accuracy. Steel pipe diameter and wall thickness of the accuracy, not only the construction and processing requirements, but also safe operation and reduce the cost requirements.
(7) Better surface quality. It is directly related to the use of performance, service life and cost reduction.
