2007年4月13日 · Weld acceptance criteria must be per API 1104 per 195.228. State jurisdictions may impose further restrictions and may limit qualification to API 1104 only. For gas piping, Arizona mandates qualification per API 1104 both outside and inside of the plant; in power plants, B31.1 does not apply to the fuel gas lines.

2009年4月15日 · Hey guys, I have to make a couple of API-1104 welding procedures for a project we are going to be working on, and was hoping to get some insight on the differences in the codes and what each code requires. I am extremely familiar with ASME Sec IX but I dont do much work with API-1104. Could...

2013年2月19日 · As per your suggestion I have posted question (c) in the API section, still awaiting answer. As weld procedures have to be qualified and tested prior to any welding to API-1104 specification you would think most API certified personnel would have a sound knowledge of the base metal requirements for procedure qualification.

2023年5月31日 · Per 1104, base material is not an essential variable when qualifying a welder, only when qualifying a procedure. Question: If the pipeline consists of only X-52 pipe, is the welder qualified to weld on this pipe per API 1104? Response from API: No. API 1104, Section 6.2.1 says “…a welder shall make a test weld using a qualified procedure…”.

2010年11月7日 · Both ASME IX and API 1104 may be used for B31.4 qnd B31.8 pipe systems. Owner's, with whose pipelines I have been associated, have specified both for over 30 years. In some cases welders must be qualified per API 1104. In both Codes production weld acceptance is per API 1104.

2014年5月13日 · As you mentioned, API 1104 indicates "As noted in Table 5, when wall thickness is over 0.500 in. (12.7 mm), the side bend tests shall be substituted for face bend or root bend tests". Note 'a' in this table also specifies "Side bend tests are substituted for face bend or root bend tests when wall thickness is over 0.500 in. (12.7 mm)".

2009年4月23日 · Hexx, As per section 5.3.2.10 of API 1104 20th edition the time between the completion of the root pass and the start of the second pass, as well as the time between the second and start of other passes must be specified in the Weld Procedure Specification (WPS).

2011年10月13日 · D1.1 is a very long intense code like everything else api writes. its over 100 pages API 1104 is something like 50 or less pages. API 1104 is piping D1.1 is structural. In your case you might want to take D1.1, but as a warning its not easy. A CWI is a CWI it doesnt matter what test you took for now. From what i have heard that will be changing.

2011年3月8日 · 1104 is a very strange code, and written for cross-country piping welded SMAW with E6010 downhill. If you will look, API-650 [tanks], 510 [vessels & boilers], and 570 [in-unit piping] all use ASME Sect IX for Procedures and Welder Qual's.

2010年11月7日 · Hi,API 1104 states "This standard covers the gas and arc welding of butt, fillet,and socket welds in carbon and low-alloy steel piping used inthe compression, pumping, and transmission of crude petroleum,petroleum products, fuel gases, carbon dioxide, nitrogenand, where applicable, covers welding on distributionsystems" It does not say anything ...
