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) ASTM D3033/3034 (PVC Pipe) ASTM D2239 (Polyethylene Pipe)
Steel casing pipe is often specified as ASTM A-252 which is a structural grade material that does not require hydrostatic testing and the inspection requirements are not stringent and it usually costs less than other grades such as A-53, [2] A-139 or API 5L. Used natural gas line pipe is also used as casing on many projects because it is often ...
In installations using hydrogen, copper and stainless steel tubing must be factory pre-cleaned (ASTM B 280) and/or certified as instrument grade. This is due to hydrogen's particular propensities: to explode in the presence of oxygen , oxygenation sources, or contaminants; to leak due to its atomic size; and to cause embrittlement of metals ...
The material with which a pipe is manufactured often forms as the basis for choosing any pipe. Materials that are used for manufacturing pipes include: Carbon steel; ASTM A252 Spec Grade 1, Grade 2, Grade 3 Steel Pile Pipe; Plastic piping, e.g. HDPE pipe, PE-X pipe, PP-R pipe or LDPE pipe. [11] Low temperature service carbon steel; Stainless steel
In addition to the descriptive steel grade naming system indicated above, within EN 10027-2 is defined a system for creating unique steel grade numbers. While less descriptive and intuitive than the grand names they are easier to tabulate and use in data processing applications. The number is in the following format: x.yyzz(zz)
The pipe was spiral welded steel made to American Petroleum Institute standards (API 5L Grade B). The pipe was brought to the site in 5.8m sections and welded together at the site. The total length of the steel pipes was covered with reinforced concrete and it was buried with soil.
ISO 18265: "Metallic materials — Conversion of hardness values" (2013) ASTM E140-12B(2019)e1: "Standard Hardness Conversion Tables for Metals Relationship Among Brinell Hardness, Vickers Hardness, Rockwell Hardness, Superficial Hardness, Knoop Hardness, Scleroscope Hardness, and Leeb Hardness" (2019)
If Type S or Type E is required for close coiling or cold bending, Grade A is the preferred grade; however, this is not intended to prohibit the cold bending of Grade B pipe. Type E is furnished either nonexpanded or cold expanded at the option of the manufacturer. 4. Materials and Manufacture of ASTM A53 Pipes
