| product name：Stainless steel seamless steel pipe for marine engineering |
product Overview:
Main features of stainless steel seamless steel pipe for marine engineering: corrosion resistance, low temperature resistance, high pressure resistance, high temperature resistance, tensile strength, flattening, flare, low temperature impact, no cracking during bending. Therefore, seamless stainless steel tubes are primarily used for fluid transport and mechanical structural applications. Including aviation, paper, petrochemical, high-pressure boilers, ships, hydropower, nuclear power, fertilizer, environmental protection, food and medical.
Stainless steel seamless steel pipe product introduction:
Stainless steel is a high alloy steel that resists corrosion in air or chemically corrosive media. From the perspective of metallography, because stainless steel contains chromium and the surface forms a very thin chromium film, this film is isolated from the intrusion of oxygen in the steel to resist corrosion.
Stainless steel seamless pipe has good resistance to intergranular corrosion, excellent corrosion performance, cold working and stamping performance, and can be used as heat resistant stainless steel. At the same time, the steel still has good mechanical properties at -180 °C. The steel has good plasticity, toughness and cold workability in the solid solution state; it is resistant to corrosion in oxidizing acids and media such as atmosphere and water. Main features of seamless stainless steel pipe: corrosion resistance, low temperature resistance, high pressure resistance, high temperature resistance, tensile strength, flattening, flaring, low temperature impact, no cracking when bending. Therefore, seamless stainless steel tubes are primarily used for fluid transport and mechanical structural applications. Including aviation, paper, petrochemical, high-pressure boilers, ships, hydropower, nuclear power, fertilizer, environmental protection, food and medical.
Industrial grade stainless steel seamless pipe
The materials that our company can supply: 304, 304L, 321, 316, 316L, 310S, 2205, etc.
Dimensions and delivery time: Zhejiang Ruixinda produces a group spacing of 10--820mm outer diameter and 1--40mm wall thickness. The maximum length is 13 meters (depending on the specific specifications), and the delivery time is generally around 15-35 days. Large amount or special system is negotiable.
Production process: According to different applications, cold drawing (annealing, pickling is a soft industrial tube) and cold rolling (even wall thickness, hard state without annealing inside and outside, and annealing into a soft industrial tube) can be used.
Zhejiang Yinyao has 4,500 tons of stainless steel seamless pipes in stock, of which 304 stainless steel pipes are mainly used. The company has passed the ISO9001:2008 quality management system standard requirements. In October 2009, it was approved by the General Administration of Quality Supervision, Inspection and Quarantine and obtained the special equipment manufacturing license (pressure piping components) of the People's Republic of China, number: TS2710L46-2018. It has complete inspection facilities such as imported direct reading spectrometer, eddy current testing and ultrasonic flaw detection to ensure the quality of products and obtain self-operated import and export management rights. The products are exported to Europe, America, Japan, Middle East and Southeast Asia countries and regions. Stainless steel tubes are well received by users at home and abroad.
