Arjun Enterprise offers collar flanges, also known as weld neck or slip on flanges, that provide a permanent leak‑proof joint in pipeline systems. These flanges are manufactured to ANSI/ASME B16.5 and DIN EN 1092 standards, ensuring compatibility with international piping projects. Materials supplied include carbon steel grade A105 and stainless steel grades 304 and 316, giving options for corrosion resistance. Size offerings cover nominal diameters from DN15 to DN600 and pressure classes ranging from Class 150 up to Class 2500.
The products are either forged from billets or fabricated from thick plates, a practice typical for flanges of this rating. A raised face is the typical sealing surface, while a flat face is also available on request. Standard bolt hole arrangements follow the typical bolt circle diameter and hole count defined in the relevant class tables. Dimensional tolerances such as flange thickness and bolt hole diameter adhere to the standard ±0.5 mm tolerance for Class 150 and tighter limits for higher classes.
Common installations include oil and gas transmission lines, chemical processing plants, water‑treatment facilities and power generation stations. Project contractors and EPC firms source these flanges in bulk for mid‑to‑large scale industrial projects where reliability and compliance are mandatory. Arjun Enterprise prepares export‑ready packaging in wooden crates or pallets with corrosion‑protective coating, and buyers should confirm MOQ, Incoterms and payment conditions directly with the supplier.

Before placing an order, importers should verify that the flanges conform to the cited ANSI/ASME B16.5 and DIN EN 1092 standards and request material test reports for the specific grade (A105, 304 or 316). Confirm the exact nominal diameter, pressure class and face type required for the intended system, and ask for dimensional drawings to avoid mismatches during installation.
Logistics considerations include confirming the preferred Incoterm - FOB or CIF - as well as the anticipated lead time for production and delivery. Because the supplier does not publish a minimum order quantity, discuss batch sizes and shipping container loading plans early. Payment terms should be agreed in writing, with typical options such as T/T against a commercial invoice or a letter of credit, depending on the buyer’s risk tolerance.
Quality assurance relies on obtaining a third‑party inspection report and, where necessary, a factory‑issued certificate of conformity. Importers are advised to arrange pre‑shipment sampling or a post‑production audit to verify dimensions, material grade and surface finish. Ensure that the supplier provides packing lists, mill test certificates and any required customs documentation to facilitate smooth clearance at the destination port.
