Weld Neck Flanges are precision-forged pipe-connection components designed for high-pressure and high-temperature service. The flanges are supplied in Carbon Steel A105, Stainless Steel 304 and Stainless Steel 316, each conforming to the ANSI B16.5 standard. Available sizes range from 1/2 inch to 24 inch nominal bore, covering pressure classes 150 through 2500. The long tapered hub provides a smooth transition to the pipe, enhancing mechanical integrity.
Carbon Steel A105 flanges typically tolerate temperatures up to 400 °C, while the stainless grades sustain up to 500 °C in continuous service. Standard thickness and bolt circle dimensions follow the ASME B16.5 tables, with a typical tolerance of +/-0.03 inch on the hub diameter. The forged construction meets the ASTM A105, A182 and A240 material specifications, ensuring consistent grain flow and fatigue resistance. These attributes make the flanges suitable for critical process piping.
The primary markets include petrochemical refineries, oil-and-gas pipelines and power-generation plants where leak-free butt-weld joints are essential. Importers such as EPC contractors, pipe-fitters and equipment manufacturers commonly source these flanges for pipelines, valve connections and pressure vessels. Arjun Enterprise offers flexible minimum order quantities and ships on FOB or CIF terms, but buyers should confirm the exact MOQ, lead time and payment conditions with the supplier.

Arjun Enterprise is located at 47/1C Hazra Road, Kolkata 700019, West Bengal, India. The company is listed as an imported-tier supplier with a harbor trust tier, and its response rate on the platform is currently zero. Arjun Enterprise specialises in supplying pipe-fitting components, including weld-neck flanges in carbon and stainless steel grades. The profile does not disclose production capacity, certifications or client references.
The supplier states that the flanges are manufactured to meet ANSI B16.5 and relevant ASTM material standards, but it does not provide specific ISO certifications. Prospective buyers should request test reports such as mill-test certificates and pressure-test results directly from Arjun Enterprise. Communication channels are limited, so confirming lead times and payment terms before placing an order is advisable.
Weld Neck Flanges are precision-forged pipe connection components engineered for high-pressure and high-temperature service in petrochemical, oil and gas, and power generation applications. Available in ANSI B16.5 standard sizes ranging from 1/2" to 24" in pressure classes 150 through 2500, these flanges feature a long tapered hub that transitions smoothly into the pipe for maximum strength and leak-free performance. EximNext supplies Weld Neck Flanges in Carbon Steel A105, Stainless Steel 304/316, and Alloy Steel grades, suitable for critical process piping systems requiring butt-weld connections and enhanced mechanical integrity.

Before placing an order, verify that the flange material grade, size and pressure class match the engineering specifications of the project. Request the latest mill-test certificates and dimensional inspection reports to confirm compliance with ANSI B16.5. It is also prudent to ask the supplier for a sample of the forging quality if the order volume justifies it.
Arjun Enterprise indicates that shipments can be arranged on FOB or CIF terms from the Kolkata port. Because the response rate is currently zero, obtain a firm lead-time estimate and confirm the incoterm that best fits your logistics chain. Payment methods such as T/T against documents or a confirmed LC should be discussed and agreed before production begins.
Arrange for a third-party inspection at the factory or during loading to verify dimensional accuracy and surface condition. Ensure that the supplier can provide pressure-test certificates and, if required, compliance with any ISO or CE standards. Maintaining a clear record of all test reports and shipping documents will facilitate customs clearance and downstream quality assurance.
