Introduction




Arc welding is a process that uses an electric arc to join metal pieces together. It is widely used in various industries, such as construction, engineering, manufacturing, oil and gas, and power generation. Arc welding can be done using manual, semi-automatic or automatic processes, depending on the level of control and automation required.


However, arc welding also involves some risks and challenges, such as distortion, cracking, corrosion, fatigue, and failure of the welded joints. To ensure the quality and safety of arc welding, there are standards and codes that provide guidelines and specifications for different types of arc welding applications.


One of these standards is BS 2633-1987, which is a British standard that covers the class I arc welding of ferritic steel pipework for carrying fluids. Ferritic steel is a type of steel that has a low carbon content and a high chromium content. It is resistant to corrosion and oxidation and has good mechanical properties. Ferritic steel pipework is used for carrying fluids such as water, steam, gas, oil, or chemicals.


What is BS 2633-1987?




BS 2633-1987 is a British standard that was published by the British Standards Institution (BSI) on May 29, 1987. It is titled "Specification for Class I Arc Welding of Ferritic Steel Pipework for Carrying Fluids". It replaces the previous version of the standard, which was published in 1973.


BS 2633-1987 defines class I arc welding as "arc welding carried out under conditions where failure would be expected to cause serious injury or loss of life". It applies to arc welding using manual, semi-automatic or automatic processes; parent metals with specified chemical compositions; welding consumables with specified mechanical properties; preparation for welding; butt joints, branches, attachments and flanges; inspection and acceptance criteria; procedure and welder approval tests.


BS 2633-1987 is intended to provide a high level of assurance that the welded joints will perform satisfactorily under the service conditions for which they are designed. It also aims to facilitate the interchangeability of welders and procedures between different organizations.


What are the benefits of BS 2633-1987?




There are several benefits of following BS 2633-1987 for the arc welding of ferritic steel pipework for carrying fluids, such as:



  • It ensures the quality and reliability of the welded joints, which can prevent leakage, rupture, or failure of the pipework.



  • It reduces the risk of accidents, injuries, or fatalities caused by faulty welding.



  • It improves the efficiency and productivity of the welding process, as it provides clear and consistent guidelines and specifications.



  • It enhances the reputation and credibility of the welding organization, as it demonstrates compliance with a recognized standard.



  • It facilitates the communication and cooperation between different parties involved in the welding project, such as designers, engineers, welders, inspectors, and customers.



Specification for Class I Arc Welding of Ferritic Steel Pipework for Carrying Fluids




In this section, we will briefly summarize the main contents of BS 2633-1987. For more details, you can refer to the full text of the standard, which is available in PDF format from various sources.


Scope of the standard




BS 2633-1987 applies to class I arc welding of ferritic steel pipework for carrying fluids. It covers pipework with nominal diameters from 15 mm to 2000 mm and wall thicknesses from 2.9 mm to 60 mm. It does not apply to pipework for nuclear applications or to pipework that is subject to cyclic loading or fatigue.


Parent metals and welding consumables




BS 2633-1987 specifies the chemical compositions and mechanical properties of the parent metals and the welding consumables that are suitable for class I arc welding of ferritic steel pipework. The parent metals are classified into four groups according to their carbon equivalent values, which indicate their weldability. The welding consumables are classified into three types according to their hydrogen content, which affects their cracking resistance.


The standard also provides guidance on the selection of the appropriate parent metal and welding consumable combinations for different service conditions and welding positions.


Preparation for welding




BS 2633-1987 specifies the requirements for the preparation for welding, such as cleaning, cutting, edge preparation, alignment, tack welding, preheating, interpass temperature control, post-weld heat treatment, and backing strips. The standard also provides guidance on the methods and equipment for these operations.


Butt joints, branches, attachments and flanges




BS 2633-1987 specifies the requirements for the design and execution of butt joints, branches, attachments and flanges. The standard also provides guidance on the dimensions, shapes, angles, gaps, root faces, root gaps, bevel angles, weld preparations, weld reinforcements, weld profiles, weld symbols, and weld sequences for these elements.


Inspection and acceptance criteria




BS 2633-1987 specifies the requirements for the inspection and acceptance criteria for class I arc welding of ferritic steel pipework. The standard also provides guidance on the methods and procedures for visual inspection, non-destructive testing (NDT), destructive testing (DT), repair welding, marking and identification of welds.


Procedure and welder approval tests




BS 2633-1987 specifies the requirements for the procedure and welder approval tests for class I arc welding of ferritic steel pipework. The standard also provides guidance on the test pieces, test conditions, test methods, test results, test certificates, validity and renewal of approvals.
