Product Applications
1. Material and composition
Stainless steel pipes are mainly composed of elements such as chromium (Cr) and nickel (Ni), and the specific composition varies according to the grade of stainless steel. For example, in 0Cr25Ni20 (also known as 06Cr25Ni20, 2520 or 310S) stainless steel pipes, the chromium content is as high as 25% and the nickel content is 20%, which makes it have excellent oxidation resistance and corrosion resistance, and can operate continuously at high temperatures.
2. Classification and specifications
There are many types of stainless steel pipes. According to the material, they can be divided into ordinary carbon steel pipes, high-quality carbon structural steel pipes, alloy structural pipes, alloy steel pipes, bearing steel pipes and stainless steel pipes; according to the production method, they can be divided into two categories: seamless pipes and welded pipes. Seamless steel pipes can be divided into hot-rolled pipes, cold-rolled pipes, cold-drawn pipes and extruded pipes, etc., and welded pipes include straight seam welded pipes and spiral welded pipes, etc.; according to the cross-sectional shape, they can be divided into round pipes and special-shaped pipes, special-shaped pipes include rectangular pipes, diamond pipes, elliptical pipes, etc.; according to the use, they can be divided into oil well pipes, pipeline pipes, boiler pipes, mechanical structure pipes, etc.
In terms of specifications, the outer diameter of stainless steel pipes usually ranges from 0.14500mm and the wall thickness usually ranges from 0.01250mm.
3. Performance characteristics
Corrosion resistance: The biggest feature of stainless steel pipes is their excellent corrosion resistance. Since stainless steel contains chromium, a passivation film will form on the surface, which effectively prevents oxidation and corrosion.
High strength and toughness: Stainless steel pipes have high strength and toughness, can withstand high pressure and high temperature environments, and are suitable for various complex working conditions.
High temperature resistance: For example, 0Cr25Ni20 stainless steel pipes have an operating temperature of up to 1200ºC and a continuous use temperature of up to 1150ºC, showing good high temperature resistance.
Sanitary: Stainless steel materials do not produce harmful substances and are widely used in industries such as food and medicine that have high requirements for sanitary conditions.
Recyclability: Stainless steel is an environmentally friendly material that can be completely recycled and reused, which is in line with the sustainable development concept of modern society.
4. Application fields
Stainless steel pipes are widely used in many fields due to their excellent performance:
Construction field: As a common pipe material in building water supply and drainage systems, it has the advantages of rust prevention, corrosion prevention, high temperature resistance, and wear resistance.
Chemical field: In industries such as petrochemicals and fertilizer production, stainless steel pipes have strong adaptability to corrosive environments, long-term stable use, and low maintenance costs.
Food manufacturing: In food processing, daily necessities manufacturing and pharmaceutical production, stainless steel pipes ensure the safety and hygiene of the transported products and avoid secondary pollution.
Automobile and shipbuilding: Used for automotive parts, ship imports and exports, and engine emission systems.
Other fields: Also widely used in boilers, heat exchangers, incinerators and other equipment that require heat resistance, as well as high-temperature furnace tubes, drying furnaces and other occasions.
Qingdao Xinquanxi Metal Products Co..Ltd. was established in 2001 (formerly known as Qingdao Quanxi Hardware Cable Co., LTD.), located in Jimo District, Qingdao city, the company was mainly engaged in the production and sales of Japanese open-body turnbuckle, die forging shackles, products are mainly sold to the United States, Russia, Japan and other countries.
In September 2019, with the continuous development of the company's business, it merged with Qingdao Ruihongjie Industry and Trade Co., LTD., and changed the company name to Qingdao Xinquanxi Metal Products Co., LTD. At the same time, the business range is gradually expanding, the main production and operation of hardware rigging, wire rope connecting parts, hardware machinery, Marine and automobile connecting parts, all kinds of forging, sheet metal, stamping, casting parts and other products.
