Arshya Pipe Fittings

If you specify or procure pressure piping components for the European market, you have almost certainly come across EN 10253-2 — the CEN standard that governs butt-welding steel fittings made from non-alloy and ferritic alloy steels. Within this standard, fittings are classified into two types, A and B, and the difference between them is not cosmetic. It directly affects the pressure rating you can safely design around. This article introduces EN 10253-2 Type B fittings: what makes them different from Type A, which steel grades fall under this standard, and where they are typically specified. Read the full technical breakdown on our website: arshyapipefittings.com . What EN 10253-2 Covers EN 10253-2 is Part 2 of the EN 10253 series of European standards for butt-welding pipe fittings. It specifies the technical delivery requirements for seamless and welded elbows, tees, reducers, and caps made of carbon and alloy steel, manufactured for pressure applications at room temperature, low te...

  If a fitting is going into a boiler-pressure-part pipeline in India, "IBR approved" isn't optional paperwork — it's the difference between a shipment clearing inspection and one sitting in a bonded warehouse for weeks. IBR (Indian Boiler Regulations) certification confirms that the pipe fittings and flanges used in steam-generating and pressure-part applications meet the safety and material-traceability requirements set by the Central Boiler Board. At Arshya Pipe Fittings, every IBR-approved component we supply is also engineered to two international dimensional and pressure-rating standards: ASME B16.9 — governs factory-made wrought buttweld fittings (elbows, tees, reducers, caps, laterals, crosses) in sizes NPS ½" through 48" ASME B16.5 — governs pipe flanges and flanged fittings from NPS ½" through 24", across pressure classes 150 to 2500 Why does pairing IBR with ASME matter? IBR confirms the component is legally cleared for use in India...

  Introduction Piping systems operating under high pressure and elevated temperature demand more than standard fittings — they require components engineered for stress, heat, and long-term structural integrity. This is where ASTM A182 becomes the defining specification. ASTM A182 governs forged and rolled alloy steel and stainless steel pipe flanges, forged fittings, valves, and parts intended for high-temperature service. It is one of the most widely referenced standards across oil & gas, petrochemical, and power generation piping design — and understanding it properly is essential for engineers, procurement teams, and fabricators sourcing critical components. This guide breaks down what ASTM A182 covers, the common fitting types manufactured under it, the material grades available, and why it remains the preferred specification for demanding industrial applications. What Is ASTM A182? ASTM A182 is a standard specification published by ASTM International that covers...

ASTM A234 by Arshya Understanding ASTM A234: The Complete Guide to Grades, Applications, and Why They Matter If you've spent any time around piping systems — in refineries, power plants, fertilizer units, or process industries — you've run into ASTM A234 more times than you can count. It's one of the most frequently specified standards for buttweld fittings anywhere in the world. And yet, ask five engineers to explain exactly what separates a WP11 fitting from a WP22 fitting, and you'll often get five different half-answers. This guide breaks down what ASTM A234 actually covers, why its grade system exists, how to choose correctly, and what happens when you don't. What Is ASTM A234, Exactly? ASTM A234 is the standard specification issued by ASTM International for wrought carbon steel and alloy steel fittings for moderate and elevated-temperature service . In plain terms, it governs the materials used to manufacture buttweld fittings — elbows, tees, reducers, cap...
