ASTM A213 Alloy Steel Pipe specification

ASTM A213 Alloy Steel Pipe

American Society for Testing and Materials (ASTM) A213 standard specifies seamless ferritic and austenitic steel pipes used in high-temperature applications such as boiler tubes, heat exchanger tubes, and related components. The standard includes various grades like T5, TP304, and others. Grades with the letter "H" are specifically designed to offer enhanced creep rupture strength compared to their non-H counterparts. ASME SA213 is a similar specification that covers chromium-molybdenum alloy steel pipes, commonly used in power generation and industrial systems.

CSC STEEL is a leading manufacturer and supplier of ASTM A213 low-alloy steel pipes available in multiple grades and sizes. We provide a wide range of seamless alloy steel pipes, including T2, T11, T12, T22, T91, and T92, in various conditions such as annealed and pickled, bright annealed, and polished, tailored to meet customer specifications.

PHA Medical Microspheres

There are many kinds of materials for preparing microspheres, which are mainly divided into natural polymer microspheres and synthetic polymer microspheres. The compatibility of microspheres is a very important aspect, including biocompatibility, which usually depends on the material from which the microsphere is prepared, and geometric compatibility, which is related to the roundness of the microsphere. There is no precise limit on the diameter of microspheres, which can generally be divided into nanospheres and microspheres. Nanoscale microspheres are also commonly referred to as nanospheres.
