What is BS EN 10253-3 - Butt-welding pipe fittings about?  
BS EN 10253-3 is a European Standard. BS EN 10253-3 is a set of guidelines for the butt welding pipe fittings and wrought austenitic and austenitic-ferritic stainless steel without specific inspection requirements.
BS EN 10253-3 specifies the technical delivery requirements for seamless and welded butt welding fittings (elbows, concentric and eccentric reducers, equal and reducing tees, caps) made of austenitic and austenitic–ferritic (duplex) stainless steel without specific inspection requirements.
BS EN 10253-3 specifies:
- Steel grades
- Mechanical properties
- Dimensions and tolerances
- Requirements for inspection and testing
- Inspection documents
- Marking
- Handling and packaging
Who is BS EN 10253-3 - Butt-welding pipe fittings for? 
BS EN 10253-3 on butt-welding pipe fittings is useful for: 
- Suppliers of butt-welding pipe fittings
- Importers of butt-welding pipe fittings
- Quality inspection services
- Testing houses for welding pipe fittings
- Manufacturers of pipes
Why should you use BS EN 10253-3 - Butt-welding pipe fittings?  
With the help of butt welding joints, the butt welding pipes are connected to the end of fittings. The requirement is to keep the diameter of the pipe and the joints similar. These joints have zero leakage and are permanently strong. The steel structures between the joints and the pipes make it strong.
BS EN 10253-3 provides users guidance on information to be obtained from the purchaser, including mandatory information, options and examples of order, ensuring accurate information disclosure to make the correct purchasing decisions.
BS EN 10253-3 provides users guidance on the manufacturing process, including the steelmaking process, product making process for fittings and heat treatment, welding and heat treatment, ensuring the strength and consistency in butt-welding pipe fittings.
With the adoption of BS EN 10253-3, users can develop and assess butt-welding pipe fittings, ensuring leak-proof operations and strong pipe fittings that assure permanent solution to leaks.
