Product Description

Product Description

The renowned ASTM A335 standard is the benchmark for assessing the formidable strength of alloy steel pipes, specifically crafted to thrive under the duress of high temperatures and pressures. Orchestrated by the distinguished American Society for Testing and Materials (ASTM), this standard encompasses an array of rigorous testing protocols. From meticulous room temperature tensile testing to the demanding high temperature tensile, compression, and bending tests, each step ensures the resilience and reliability of the pipes.
Application Area
The ASTM A335 standard serves as a cornerstone in the engineering and crafting of pipeline systems within industries that operate at the nexus of heat and pressure, such as petroleum, chemical, and power sectors. By adhering to this standard's stringent testing regime, one can guarantee the alloy steel pipes' robustness and safety, even in the most challenging high temperature environments.
Specific Products and Their Uses
Under the esteemed ASTM A335 standard, specific products like the illustrious P11 alloy seamless tubes play a critical role. These stalwarts are employed in vital components such as heating surfaces, economizers, headers, superheaters, reheaters, and pipes within the petrochemical industry, especially in high-pressure boilers. Their utility spans various high-pressure boiler applications across fields like petroleum, chemical, power, and even aerospace, where precision and durability are paramount.
  A209 alloy pipe is an American standard alloy steel pipe, which not only has high oxidation resistance and high-temperature steam corrosion resistance, but also has good impact toughness and high and stable durability plasticity and thermal strength performance. Mainly used for steel pipes for super boiler tubes, high-temperature superheaters, reheaters, high-temperature headers, and steam pipelines. It can also be used as nuclear electric heat exchangers and furnace tubes for petroleum cracking units.
ASTM A213 steel pipes are mainly used for equipment such as boilers, superheaters, and heat exchangers, and are suitable for high-temperature and high-pressure working environments
  Specific Use: 
  Boiler and Superheater: ASTM A213 steel pipes are suitable for boilers and superheaters, especially those components that need to withstand high temperature and high pressure environments. These steel pipes are commonly used for heating surface tubes, economizers, superheaters, and reheaters in high-pressure boilers (with working pressures generally above 9.8 MPa and working temperatures between 450 ºC and 650 ºC)
  Heat exchanger: ASTM A213 steel pipes are also used in heat exchangers, especially in environments that require high temperature and corrosion resistance. These steel pipes have good high temperature resistance and corrosion resistance, and can adapt to harsh working environments in heat exchangers
  The chemical composition and mechanical properties of ASTM A213 steel pipes make them excellent in high temperature and high pressure environments. Common grades such as T11, T12, T22, etc. have chemical compositions including elements such as carbon, silicon, manganese, as well as alloying elements such as chromium and molybdenum. These elements endow steel pipes with excellent high temperature resistance and corrosion resistance. For example, chromium element improves the oxidation resistance and corrosion resistance of steel pipes, while molybdenum element enhances their thermal strength
