Import Barrel Pipe Nipple C Class Heavy Duty — Buy in wholesale FOB from Supplier in India

The Barrel Pipe Nipple C Class Heavy Duty from Tirupati Sheet Metal WLL is a forged malleable cast iron threaded fitting engineered for medium-pressure fluid and gas conveyance in industrial piping networks. Manufactured to Class C pressure rating from malleable cast iron (also designated Cast Iron Grade A), this fitting provides reliable threaded connections for water supply, HVAC, oil and gas distribution systems. Available in trade sizes from 1/2 inch to 2 inches with standard BSP or NPT thread forms, it serves as a critical intermediate connector between pipe sections, valves, and equipment in both commercial and industrial installations.

Class C malleable iron fittings derive their strength from a controlled annealing process that converts white cast iron into temper carbon, yielding a material with tensile strength typically 340 N/mm² and elongation of 10-15%. The barrel nipple form features parallel threads at both ends with a smooth cylindrical body between the threaded portions, allowing for close-tolerance installation where space is constrained. Standard material composition includes carbon 2.3-2 Faber%, silicon 1.0-1.4%, with manganese and sulfur controlled to ensure machinability and thread integrity. The heavy duty designation indicates thicker wall sections compared to standard class variants, providing additional safety margin in cyclic pressure applications.

This fitting is purchased by plumbing contractors, mechanical engineering firms, water works departments, and industrial maintenance teams across infrastructure, building services, and petrochemical sectors. For import buyers, containerised bulk orders are the typical procurement mode from Indian malleable iron foundries. Buyers should confirm thread standard (BSP taper or NPT), exact length of the nipple barrel, and whether galvanised or black finish is supplied. Pressure test certificates and material mill reports should be requested for critical applications, as Class C ratings vary slightly between IS 1879, BS EN 10242, and ASTM A197 standards.

Tirupati Sheet Metal WLL operates from 122 L.R. Belelious Lane, Howrah, West Bengal 711101, India, a location within the historic foundry belt of Howrah that has specialised in metal casting and pipe fittings for over a century. The company's harbour trust tier indicates a verified business presence on the platform, though the response rate of 0.00% and zero average response hours suggest limited active engagement through digital channels. Buyers should anticipate direct communication challenges and plan for alternative contact methods or representative follow-up when initiating procurement discussions.

The supplier profile does not disclose production capacity, workforce size, annual turnover, or specific client references. No certifications, export licence details, or quality management accreditations are stated. The company specialises in sheet metal and cast iron pipe fittings, with the Barrel Pipe Nipple C Class Heavy Duty representing a standard product in their catalogue. Buyers are advised to request factory audit reports, sample shipments, and third-party inspection documentation before committing to volume orders, given the absence of detailed verification data in the available profile.
