BS EN 10253-1 is an international standard that deals with the specifications for pipe fittings depending on different aspects.
BS EN 10253-1 specifies the requirements for steel butt-welding fittings (elbows and return bends, concentric and eccentric reducers, equal and reducing tees, dished ends and caps) made of wrought carbon steel and delivered without specific inspection.
BS EN 10253-1 specifies:
Note: The fittings described in BS EN 10253-1 do not fulfil specific design requirements, consequently, they cannot be considered as conforming to the essential requirements of the pressure equipment directive.
BS EN 10253-1 on butt-welding pipe fittings is relevant to:
The butt-welding pipelines and pipe fittings are used in fluid transportation, such as in gas and oil industries, worldwide. They are usually safeguarded with extruded polyethylene-based coatings and cathodic protection. It is the most popular coating product used for covering steel pipelines. The two-layer extruded polyethylene coating provides exceptional corrosion defense to pipelines and pipe fittings.
BS EN 10253-1 provides you with guidance for technical specifications of butt-welding pipe fittings, such as fitting manufacture, surface conditions, the material used for pipe fittings, chemical composition as well as weldability that are in compliance with international standards.
BS EN 10253-1 gives you information about the dimensions and tolerances of butt-welding pipe fittings, which helps the users to understand and decide the standard thickness, width, and length of butt-welding pipe fittings.
Users of BS EN 10253-1 can get guidance on the protection measures and use the references for testing and inspection procedure for butt-welding pipe fittings, which helps in enhancing the life of the pipe fittings.
Thus, BS EN 10253-1 provides you with comprehensive information useful for producing high-quality, cost-effective, durable butt-welding pipe fittings with minimum or no manufacturing defects.
