304 seamless pipe is today's environmental protection pipe with the best possible comprehensive performance.

304 seamless pipes are trustworthy, clean, hygienic, ecological and environmental protection, and can be used for social and economic development. The thin-walled pipeline and the design and development of new reliable, simple, convenient and quick connection methods make it have the irreplaceable advantages of other pipelines. There will be more and more applications in engineering, the application will be more perfect, and the industry prospect is promising.

304 seamless pipe features and main uses

304 seamless pipe combines the characteristics of alloy composition and austenite, and has good resistance to chloride ion content composition stress field and corrosion cracking resistance. 2205 is a dual-phase steel consisting of 21% chromium, 2.5% molybdenum and 4.5% nickel nitrogen alloy. Its yield strength is twice that of austenitic stainless steel sheet. This capability enables industrial designers to reduce net weight when conceptualizing merchandise. It has many advantages over the 316 and 317L. Due to the high content of chromium and molybdenum, the steel has good pitting resistance and average corrosion energy. The two-phase structure ensures that the stainless steel plate has high resistance to stress corrosion cracking and high fracture toughness.

304 seamless pipes have good performance indicators and corrosion resistance, as well as good laser weldability. Widely used in industrial production of petrochemical equipment, marine technology, chemical enterprises and other industries. At present, the petrochemical pipelines laid by dual-phase steel in the petrochemical equipment industry are more than 850Km long, and 304 stainless steel seamless steel pipes are mostly seen (there are also S31803 dual-phase steel pipes and 2507 dual-phase steel pipes); Chemical corrosion, high pressure pipes are made of 304 stainless steel seamless pipes.

304 seamless pipe has the following scope of application:

Industrial production of chemical plants, petrochemical equipment chemical enterprises, transportation pipelines of chemical enterprises, petroleum and natural river industry, paper industry, paper industry, organic fertilizer industrial production, urea solution aqueous solution industrial production, phosphorus and potassium fertilizer industrial production, sea level geographical environment, energy ecological environment Protect industrial production, biological industry in light industry, machinery and equipment in food industry and pharmaceutical industry, and high wear-resistant parts.
