In some areas A.S.T.M. specifications may be required by project engineers. The specification most commonly called for is A.S.T.M. 139 Grade B. This specification gives parameters for minimum yield and tensile strength of the steel pipe being used for casing, and tolerances of straightness and concentricity.
Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures. [1] " Nominal" refers to pipe in non-specific terms and identifies the diameter of the hole with a non-dimensional number (for example – 2-inch nominal steel pipe" consists of many varieties of steel pipe with the only criterion being a 2.375-inch (60.3 mm) outside ...
2. Application of ASTM A53 Standard Pipes Steel Pipes ordered under this specification is intended for mechanical and pressure applications and is also acceptable for ordinary uses in steam, water, gas, and air lines. It is suitable for welding, and suitable for forming operations involving coiling, bending, and flanging. 3. Types and Grades ...
Some widely used pipe standards or piping classes are: The API range – now ISO 3183. E.g.: API 5L Grade B – now ISO L245 where the number indicates yield strength in MPa; ASME SA106 Grade B (Seamless carbon steel pipe for high temperature service) ASTM A312 (Seamless and welded austenitic stainless steel pipe) ASTM C76 (Concrete Pipe)
Pipes used to convey fuel gas are often made of "black iron", which has been chemically treated to reduce corrosion, but this treatment does not resist erosion from flowing water. Despite its ruggedness, steel pipe is no longer preferred for conveying drinking water because corrosion can eventually cause leakage (especially at threaded joints ...
Moreover, the 3D pipe stress determines the bending moments of the pipes. Allowable (ASME) Pipe grades permitted for Oil and gas industries are : Carbon Steel Pipes and tubes (A53 Grade [A & B], A106 Grade [B & C]), Low & Intermediate alloy steel Pipes (A333 Grade [6], A335 Grade [P5, P9, P11, P12, P91])
ASTM A500 is a standard specification published by the ASTM for cold-formed welded and seamless carbon steel structural tubing in round, square, and rectangular shapes. It is commonly specified in the US for hollow structural sections , but the more stringent CSA G40.21 is preferred in Canada.
ASTM International, formerly known as American Society for Testing and Materials, is a standards organization that develops and publishes voluntary consensus technical international standards for a wide range of materials, products, systems and services. Some 12,575 apply globally.
