API 5L Pipeline Inspection and TestingJune 29, 2022
The API 1104 standard, developed by the American Petroleum Institute (API), is the industry standard for welding applications. This standard provides a method for producing high-quality welds in a novel and understandable format using qualified welders, approved welding procedures, materials and equipment. The full name of the standard is as follows: API 1104 Welding of Piping and Related Facilities.
This standard contains detailed and multi-year industry information and provides inspection methods to authorized organizations to ensure accurate analysis of weld quality using qualified technicians and approved methods and equipment.
The API 1104 standard covers gas and arc welding of low alloy steel pipe bottom, fillet and socket welds. These pipes are used to compress, pump and transport products such as crude oil, petroleum products, gas, carbon dioxide and nitrogen.use. This standard applies to welding operations on new or in-service piping. The welding operation may be in the form of shielded metal arc welding, submerged arc welding, gas tungsten arc welding, gas metal arc welding, hollow arc welding, plasma arc welding, oxyacetylene welding or flash butt welding. Alternatively, manual, semi-automatic, mechanical or automatic welding techniques or a combination of these techniques may be applied.
The standard also provides inspection methods to ensure accurate analysis of weld quality using qualified technicians and approved methods and equipment. It includes radiographic, magnetic particle, liquid penetrant and ultrasonic testing procedures.
Simply put, the API 1104 standard is a standard that provides methods for producing high-quality welds by employing qualified welders and using approved welding procedures, materials, and equipment.
Within the scope of metal testing services, API 1104 standard testing is also included in the services offered by our organization.
