ASME SB / ASTM B388 Grade 7 Titanium Alloy Pipes

ASME SB and ASTM B388 are standards for titanium alloy pipes. These standards provide specifications for the chemical composition, mechanical properties, and dimensional requirements of titanium alloy pipes.

ASME SB is a standard published by the American Society of Mechanical Engineers (ASME). It provides specifications for seamless and welded titanium alloy pipes for general corrosion-resistant and elevated-temperature service. The standard covers various grades of titanium alloys, including Grades 1, 2, 3, 7, 9, 11, 12, 16, 17, 26, and 28.

ASTM B388 is a standard published by the American Society for Testing and Materials (ASTM). It provides specifications for seamless and welded titanium alloy pipes for general corrosion-resistant and elevated-temperature service. The standard covers various grades of titanium alloys, including Grades 1, 2, 3, 7, 9, 11, 12, 16, 17, 26, and 28.

Both standards specify the chemical composition, mechanical properties, and dimensional requirements of titanium alloy pipes. They also provide guidelines for testing methods, heat treatment, and marking of the pipes. These standards ensure the quality and reliability of titanium alloy pipes used in various industries, including aerospace, chemical processing, and marine applications.

Grade 7 titanium alloy pipe is a type of pipe made from a titanium alloy known as Grade 7. This alloy is composed of 99.2% pure titanium, with small amounts of palladium added to improve its corrosion resistance.

Grade 7 titanium alloy pipe is known for its excellent corrosion resistance, especially in environments containing chlorides. It is also highly resistant to erosion and has good strength and toughness properties. These characteristics make it suitable for a wide range of applications, particularly in industries such as chemical processing, marine, and aerospace.

The pipe is typically manufactured using a seamless process, ensuring a uniform and smooth surface finish. It is available in various sizes and thicknesses to meet different application requirements. Grade 7 titanium alloy pipe can be welded using standard welding techniques, although care must be taken to prevent contamination and ensure the integrity of the weld.

Overall, Grade 7 titanium alloy pipe offers a combination of corrosion resistance, strength, and durability, making it a popular choice for demanding applications where reliability and performance are critical.

ASME SB / ASTM B388 1, 2, 3, 5, 7, 8, 9, 11, 12, 23 and other titanium alloy pipes are certified and tested according to hardness test, hydrostatic test, eddy current test, eddy current test, tensile test, Flattening, expansion test, annealing, hydrostatic test, tempering, stress relief, etc.
