A kind of marine pressure vessel bottle and production method thereof

Abstract

The invention discloses a pressure container bottle for maritime work and a production method of the pressure container bottle, and belongs to the technical field of pressure container production. A seamless superaustenitic stainless steel pipe with the diameter larger than or equal to 400 mm is manufactured firstly, then, the seamless superaustenitic stainless steel pipe is used for manufacturinga seamless superaustenitic stainless steel pressure container bottle inner container, then, a carbon fiber rope is adopted, winding, dipping and curing are conducted on the outer surface of the seamless superaustenitic stainless steel pressure container bottle inner container, a carbon fiber winding resin strengthened layer is formed, and a pressure container in which the outer surface of the inner container is provided with the strengthened layer is obtained. The product is light and high in strength, fatigue resistance and corrosion resistance, and has the advantages of being resistant to seawater corrosion, free of welding lines, resistant to the high pressure, small in mass, high in fatigue filling performance and the like.

Description

technical field [0001] The invention belongs to the technical field of pressure vessel production. [0002] technical background [0003] At present, there are mainly the following types of pressure vessel bottles for marine engineering: [0004] 1. The pressure vessel bottle made of ordinary stainless steel seamless steel pipe has low seawater corrosion resistance and short service life. It needs to be replaced regularly, which increases maintenance and operating costs; [0005] 2. The pressure vessel bottle made of titanium alloy material has a good affinity for organisms. When used in seawater, seawater microorganisms adhere to the inner and outer surfaces of the pressure vessel bottle, forming biological pollution and posing safety hazards. Due to the difficulty in processing seamless steel pipes and bottle mouths made of titanium alloy materials, the product yield is low, and the price of titanium alloy materials is high, making pressure vessel bottles made of titanium ...

AI Technical Summary

Problems solved by technology

[0004] 1. The pressure vessel bottle made of ordinary stainless steel seamless steel pipe has low seawater corrosion resistance and short service life. It needs to be replaced regularly, which increases maintenance and operating costs;

[0005] 2. The pressure vessel bottle made of titanium alloy material has a good affinity for organisms. When used in seawater, seawater microorganisms adhere to the inner and outer surfaces of the pressure vessel bottle, forming biological pollution and posing potential safety hazards.

Due to the difficulty in processing seamless steel pipes and bottle mouths made of titanium alloy materials, the product yield is low, and the price of titanium alloy materials is high, making pressure vessel bottles made of titanium alloy materials expensive;

[0006] 3. The pressure vessel bottle for marine engineering using pure metal materials must withstand higher pressure, and the wall thickness of the pressure vessel bottle needs to be thickened, thereby increasing the weight of a single bottle body. The pressure vessel used on marine engineering equipment The large number of bottles increases the overall weight of offshore equipment and hinders the development of lightweight and energy-saving offshore equipment
