JIS G3429 is a Japanese standard that specifies seamless steel tubes for high-pressure gas cylinders. These steel tubes are widely used in various industries, including fire-fighting, industrial, and vehicle gas cylinders. In this article, we will explore the applications and grades of JIS G3429 steel pipes for gas cylinders.


The U Bend ASTM A209 Alloy Steel Boiler Pipe is a high-quality seamless carbon-molybdenum alloy steel Pipe designed for high-temperature and high-pressure applications in boilers and heat exchangers. With its strict adherence to the ASTM A209 standard, it offers excellent chemical composition and mechanical properties. The Pipe undergoes heat treatment and mechanical tests to ensure its durability, reliability, and optimal performance. Whether in power generation, petrochemical, or refinery industries, the U Bend ASTM A209 Alloy Steel Boiler Pipe is a reliable choice for efficient heat transfer and long-term operation.


In conclusion, the ASTM A790 UNS S31803, UNS S32750, and UNS S32760 duplex stainless steel pipes are highly versatile and reliable in various industries. Their unique combination of corrosion resistance and high strength properties make them ideal for applications in chemical processing, oil and gas, marine environments, and more. With precise dimensions and adherence to the ASTM A790 standard, these pipes provide exceptional performance and durability. Whether it's transporting corrosive chemicals, withstanding high-pressure conditions, or resisting harsh marine environments, duplex stainless steel pipes are the go-to choice for many industries.


ASME SA249 TP316L Stainless Steel Boiler Pipe possesses excellent mechanical properties, including high tensile and yield strength, elongation, and impact toughness. The manufacturing process ensures a seamless and robust structure, while the chemical composition provides superior corrosion resistance and high-temperature stability. These attributes make TP316L stainless steel a reliable choice for boiler pipe applications in various industries.


ASMEB 16.5 stainless steel butt weld pipe fittings are vital components in the construction of reliable and efficient piping systems. These fittings, adhering to a recognized standard, provide precise and secure connections between pipes, ensuring a seamless flow of fluids. Whether it is for the oil and gas, chemical processing, or other industries, stainless steel butt weld pipe fittings offer the necessary strength and corrosion resistance to maintain the integrity of piping systems. By selecting high-quality fittings and adhering to the ASMEB 16.5 standard, industries can ensure the efficiency and reliability of their piping systems, contributing to the overall success of their operations.


Schedule 80 piping exhibits clear structural superiority versus Schedule 40 through its 25-30% thicker walls, translating to higher strength, stiffness, load tolerance, deflection resistance and durability in demanding applications. Its robustness and performance make it the standard choice for structural pipe supports.


According to ASTM specifications, this particular specification pertains to seamless ferritic and austenitic steel tubes for use in boilers, superheaters, and heat exchangers. The specific grades covered by this specification include T5, TP304, and others listed in Tables 1 and 2. The tubing size ranges from an internal diameter of 1/8 inch up to an outer diameter of 5 inches, with thicknesses ranging from 0.015 to 0.500 inches (0.4 mm to 12.7 mm). If other sizes are required, they can be specified as part of the order, along with minimum and average thicknesses.
