Bhavani Industries is a leading manufacturer and supplier of high-quality Buttweld End Caps, also known as Pipe Caps, designed to effectively seal the ends of piping systems. These fittings serve a vital function by closing off unused pipe openings, preventing leakage, protecting pipe ends from mechanical damage, and keeping out moisture, dirt, or other contaminants. End caps are typically welded to the end of a pipe to create a permanent and secure closure, making them ideal for both temporary and permanent piping terminations in industrial systems.
We offer end caps in a wide range of sizes from ½” to 48” (DN15 to DN1200) with wall thickness options ranging from SCH 5 to SCH 160 / XXS. All products are manufactured in accordance with international standards such as ASME B16.9, ASTM A234, ASTM A403, MSS-SP-75, and EN 10253, ensuring precision, strength, and leak-proof performance. Manufactured using advanced methods like hot and cold forming, machining, and beveling, each end cap is finished to ANSI B16.25 standards for weld preparation, making installation smooth and reliable under high-pressure and high-temperature conditions.
Our end caps are available in a variety of materials to suit different industrial needs, including Stainless Steel (304, 304L, 316, 316L, 321, 347, 904L), Carbon Steel (ASTM A234 WPB, WPC), Alloy Steel (WP5, WP11, WP22, WP91), and Nickel Alloys (Inconel, Monel, Hastelloy, Alloy 20). These materials are carefully selected based on their corrosion resistance, mechanical strength, and suitability for critical service conditions. Our end caps are widely used in oil and gas, petrochemical, power generation, marine, water treatment, and chemical processing industries, where safe and durable pipeline closure is essential.
The use of buttweld pipe caps offers numerous advantages such as secure sealing of pipelines, protection from environmental exposure, elimination of flow disruptions, and cost savings by avoiding the need for additional valves or equipment at pipe ends. To ensure top-tier quality, every end cap undergoes stringent testing including PMI (Positive Material Identification), Ultrasonic Testing (UT), Radiography (RT), Hydrostatic Testing, and third-party inspections as per client requirements. Bhavani Industries remains committed to delivering precision-engineered end caps that ensure reliability, durability, and performance in the most demanding industrial applications.
