Import A105 Flanges — Buy in Bulk from Supplier in India

A105 flanges are forged carbon steel pipe flanges designed for low-pressure and ambient-temperature service in accordance with ASTM A105 / A105M. Metal Aids India lists these in common configurations including slip-on, weld neck, blind, and socket weld types, giving buyers flexibility across installation scenarios. The A105 grade specifies a carbon steel with 0.35% max carbon, 0.60-1.05% manganese, and controlled sulphur and phosphorus levels, delivering adequate tensile strength for non-critical piping systems. Typical pressure classes span 150# through 300# under ASME B16.5, with raised face (RF) and flat face (FF) finish options standard across the industry.

The material is normalised or fully killed carbon steel, which minimises internal stresses and improves weldability compared to rimmed or semi-killed alternatives. Buyers often specify Charpy V-notch impact testing for sub-zero service, though this is not standard A105 and must be requested as supplementary requirement S5 or S8 under ASTM A105. Surface finish is typically machined to a 125-250 AARH (Arithmetic Average Roughness Height) for gasket seating. Coating options include black paint, rust-preventive oil, or hot-dip galvanising, depending on storage and environmental exposure during transit and installation.

These flanges serve oil and gas gathering lines, water treatment plants, HVAC distribution, and general structural piping where pressure ratings remain below 285 psi at ambient temperature. The buyer profile includes EPC contractors, maintenance procurement teams, and industrial distributors who need batch consistency and traceable mill test reports. Metal Aids India operates as an imported-tier supplier with harbor trust status; buyers should confirm current stock depth, mill source, and whether test reports accompany each heat lot before committing to volume orders.

Metal Aids India is listed as an imported-tier supplier on the platform with harbor trust designation, which indicates a baseline verification level rather than premium or gold status. The supplier profile does not disclose years in operation, factory location within India, headcount, revenue figures, or specific clientele, so none of these can be stated with confidence. The response rate is recorded at 0.00% with zero average response hours, signalling that buyers should expect communication delays and may need to follow up through multiple channels to secure quotations or technical clarifications.

The listing presents Metal Aids India as a source for A105 carbon steel flanges in standard ASME configurations, though it does not specify whether the company manufactures directly or trades through mill relationships. Buyers should verify the supplier's actual role in the value chain, request mill test certificates for traceability, and confirm whether stock is held domestically in India or sourced on indent. The harbor trust tier suggests basic documentation review; it does not substitute for buyer-conducted due diligence on quality systems or financial stability.
