Ambani Metals is an established industrial manufacturer and international supplier of precision-engineered perforated pipes and tubular filter screens based in India. With over two decades of metallurgical manufacturing expertise, we engineer high-strength perforated tubing in Stainless Steel (304/304L, 316/316L, 321), Carbon Steel, High-Strength Alloy Steel, and Aluminium. Our automated punching, roll-forming, and seam-welding capabilities guarantee concentric dimensional stability, clean burr-free perforations, uniform open area distribution, and verifiable pressure resistance. Designed to comply with ASTM, ASME, and API engineering specifications, our products are globally trusted by engineering procurement contractors across the Middle East, North America, Europe, and Asia-Pacific.
Engineered to handle severe hydraulic mechanical loads, corrosive chemical fluids, and extreme thermal environments.
Manufactured from premium SS 304, 304L, 316, and 316L grades. Exceptional corrosion resistance, structural integrity under high pressure, and non-contaminating properties for chemical, pharmaceutical, and water desalinization units.
High-tensile strength carbon steel perforated tubing designed for mechanical durability, downhole casing, exhaust silencers, and civil dewatering. Available with hot-dip galvanized or protective anti-corrosion coatings.
Formulated with chromium-molybdenum and specialized nickel alloys for elevated temperature, corrosive, and sour-gas environments in upstream oil & gas drilling, refining, and power generation boilers.
Lightweight, oxidation-resistant perforated tubing offering an exceptional strength-to-weight ratio. Ideal for aerospace ventilation, civil sub-drainage, acoustic silencers, and modern architectural façades.
Industrial perforated pipes operate as the critical structural core in fluid separation, acoustic baffling, and subterranean soil drainage. By combining heavy hydraulic shearing, CNC multi-station punching, and automated longitudinal/spiral seam welding, Ambani Metals produces tubing that handles demanding mechanical collapse pressures without geometric deformation.
Our perforated pipe products are integrated into mission-critical infrastructure across five continents, delivering significant advantages over non-perforated or slotted alternatives.
Standard and bespoke dimensional matrices built to comply with global pressure piping and mechanical tubular standards.

We fabricate round, slotted, rectangular, bridge-slot, and spiral perforation patterns. Hole diameters range from micro-perforations of 0.8 mm up to 50 mm, with custom hole pitches and open area ratios ranging from 5% to 65% tailored to meet specific collapse strength and hydraulic throughput parameters.
Every batch is supplied with an EN 10204 3.1 Material Test Report (MTR) detailing chemical analysis and mechanical properties. In-house testing includes positive material identification (PMI), hydrostatic pressure testing, weld radiography or ultrasonic tests, roundness and straightness dimensional verification, and third-party inspection (TUV, SGS, Bureau Veritas, DNV).
Depending on wall thickness and pipe diameter, we utilize longitudinal TIG (GTAW), continuous High-Frequency (ERW), and automated Submerged Arc Welding (SAW). For high-collapse downhole well screens and large diameters, spiral seam welded structures are also manufactured.
Pipes are cleaned, deburred, passivated (for stainless steel), and coated with rust-preventive oil (for carbon/alloy steel). Bundles are secured with heavy-duty steel strapping, wrapped in waterproof poly-sheeting, protected with bevel end caps, and crated in heat-treated ISPM-15 compliant wooden boxes or steel frames for containerized shipping.
