What standards will stainless steel pipes have in design
Stainless steel pipe inner diameter of more than 30mm, wall thickness of more than 1.2mm sβtainless steel pipe Roche hardness tester, test HRB, HRC hardness. The stainless  steel pipe with an inner diameter of more than 30mm and a wal↔l thickness of less than 1.2mm uses an external Rockwell hardness tester to tes&t HRT and HRN hardness. The inner diameter is less than 0mm, the stainless steel÷ pipe is less than 4.8mm, and the hardness of HR15T is¥ tested by using a special hardness tester for pipes. When the inner diameter of the stainle​ss steel pipe is more than 26mm, the hardness of the inner wall of the pipe can also≤ be tested with Roche or external Roche hardness tester.

To carry out the editing, the two ends are open, there is a hollow section, the length and the se×ction circumference of the relatively large steel can be called steel↕ pipe. When the length is small compared to the circumferen ce of the section, it can be called pipe segments and tubular parts, which belong to the catego ry of pipe products, and architects continue to choose stainless steel for• the construction of cost-effective permanent buildings. Many existing bui'ldings fully illustrate the correctness of this choice.

The Chrysler building in New York City, etc., is also very popular. However, in many other appli✘cations, the role of stainless steel is not so noticeable, but plays an important role in the aest×hetics and performance of buildings. For example, stainless steel has  abrasion resistance and pressure resistance compared with other meta±ls of the same thickness, so it is a priority for designers when constructing sidewalks in centra§l areas with large population activities.

Stainless steel has been used for more than 70 years in the construction of↕ new buildings and the restoration of structural materials of historic♦ sites. Early designs were calculated based on basic rope stπops. Today, design standards such as the Institution of C"ivil Engineers specification ANSI/ASCE-8-90 "Design Standard for Coldβ-formed Stainless Steel Structures" and the "Design Manual for Structural Stainl∏ess Steel" published in conjunction with NiDI and Euro Inox simplify the≠ design of long-life, intact building structures.
