Hot Selling SCH 10 Duplex Stainless Steel Pipe Ensures Safe Fluid Transfer

As an important part of the chemical industry, the petrochemical industry encompasses many production sectors, such as chemical fertilizers, rubber, synthetic materials, papermaking, coating, chemicals, and other industries.

Corrosion poses a significant threat to the integrity and safety of pipelines in the oil, chemical, and gas industry. It can cause leaks, pipeline failures, and environmental hazards.

Common corrosive compounds encountered in petrochemical and natural gas industry processes: sulfur， naphthenic acid, polythionic acid， chlorides， carbon dioxide， ammonia， cyanides， hydrogen chloride， sulphuric acid， hydrogen， phenols, oxygen, and carbon. Therefore, selecting the right materials for pipelines becomes crucial in mitigating corrosion risks. To address these challenges, seamless pipes have emerged as a preferred choice for the industry.

Seamless pipes for petrochemical and gas applications possess several distinct features, resistance to high pressure, temperature, stress & corrosive atmosphere. Seamless pipes are engineered to withstand conditions commonly encountered in the petrochemical, oil, and gas industries. Stainless steel petrochemical pipe can handle high pressures, temperatures, stress, and corrosive environments, ensuring the safe and efficient transport of fluids.

Features of stainless steel for petrochemical equipment:

Cr-Ni and Cr-Ni-Mo austenitic stainless steels are widely used in petrochemical equipment due to their good corrosion resistance, plasticity, toughness, formability, and weldability.

In order to meet the intergranular corrosion resistance requirements during thermal processing and welding, petrochemical equipment often uses stainless steel materials containing stable elements such as titanium and niobium, such as 07Crl9NillTi (321H), 06Crl7Ni12Mo3Ti (316L), etc. Options that include these stabilizing elements. With the advancement of metallurgical technology, low-carbon, ultra-low-carbon, and nitrogen-containing stainless steels are becoming more and more widely used due to their better resistance to intergranular corrosion and knife line erosion.

Specific applications of stainless steel petrochemical pipes in the petrochemical industry: 1. Chemical reactors and heat exchangers; 2. Transporting high-temperature and high-pressure media; 3. Oil and natural gas detection; 4. Chemical storage tanks.
