Offshore platforms, Andean mining operations, and coastal desalination facilities all demand piping components built for serious conditions. As a leading Chinese stainless steel flanges manufacturer, we wanted to put together a list of suppliers that can help procurement teams source the right components for this market. Given that many projects often require INMETRO compliance and that large-diameter flanges require specialised logistics handling for international shipment, we were careful to focus on manufacturers who understand what operating in this region involves. Here’s our list of the top ten stainless steel flange manufacturers and suppliers worth knowing in South America. ## **South America’s Top Stainless Steel Flange Manufacturers at a Glance** Below is a quick overview of each manufacturer, their base of operations, and what they specialise in: | **Manufacturer** | **Base** | **Core Specialization** | **Certifications** | | --- | --- | --- | --- | | Provaltec | Santiago, Chile | High-abrasion mining infrastructure | ISO 9001, Bureau Veritas | | Grupo Flanjaço | São Paulo, Brazil | Custom heavy machining and large disks | INMETRO, ISO 9001 | | Amersa Perú | Lima, Peru | High-pressure industrial connections | ASTM A182, ANSI B16.5 | | Gapiza | Rio de Janeiro, Brazil | Hydraulic and offshore component forgings | INMETRO, Offshore Certified | | Fittings y Llaverias | Santiago, Chile | Large-diameter waterworks connections | ISO 9001, ASV | | TyP Colombia | Bogotá, Colombia | Multi-industry fluid logistics connections | ISO 9001, ANSI B16.5 | | QG Inox | São Paulo, Brazil | High-density industrial connections | INMETRO, Petrobras Quality | | Corporación GMA Perú | Lima, Peru | Petrochemical and fluid handling | ASTM, ANSI Standards | | Traficaño | Buenos Aires, Argentina | Heavy-gauge industrial system elements | ISO 9001, International Standards | | Acepil | São Paulo, Brazil | Multi-grade pipeline connections | INMETRO, Sanitary Grade | Let’s get into each one. ### **1. Provaltec** **Location:** Santiago, Chile **Founded:** 1991 **Compliance:** ISO 9001, Bureau Veritas Mining Approval ![Provaltec](https://www.longanflange.com/wp-content/uploads/2026/06/图片12.webp) Provaltec has built its name around the Andean mining corridor, producing pipeline components that handle some of the most abrasive material transport conditions you’ll find anywhere in the region. Their heavy machining lathes shape large-diameter industrial disks built for the copper extraction industry, where components face continuous wear from thick mineral slurry streams. The hub profiles on their slip-on and blind variants are reinforced specifically to resist the internal scouring that wears out standard components fast. ### **2. Grupo Flanjaço** **Location:** São Paulo, Brazil **Founded:** 2005 **Compliance:** INMETRO, ISO 9001 ![Grupo Flanjaço](https://www.longanflange.com/wp-content/uploads/2026/06/图片13.webp) Grupo Flanjaço is one of Brazil’s leading high-capacity manufacturers, running advanced CNC machining centres and vertically integrated raw material cutting setups. They process high-purity 304L and 316L stainless steel blocks into heavy-duty connectors with serrated raised faces and precise bolt-hole alignments. Full INMETRO compliance makes them a practical choice for domestic oil and gas projects where certification paperwork needs to be airtight. ### **3. Amersa Perú** **Location:** Lima, Peru **Founded:** 2010 **Compliance:** ASTM A182, [ANSI B16.5](https://www.longanflange.com/wp-content/uploads/wp-mfa-exports/post/asme-b16-5-pipe-flange-fitting-definition.md), DIN/JIS Standards ![Amersa Perú](https://www.longanflange.com/wp-content/uploads/2026/06/图片14.webp) Amersa Perú supplies high-pressure pipe connections across Peru’s industrial landscape, stocking and finishing international grades like T304L and T316L across sizes from 1/2″ up to 12″ for pressures up to 2500 lbs. Their internal bore diameter matching reduces fluid turbulence and minimises localised wear at joint connections, which adds up over time in high-pressure systems running continuously. ### **4. Gapiza** **Location:** Rio de Janeiro, Brazil **Founded:** 2006 **Compliance:** INMETRO, Onshore and Offshore Maritime Certifications ![Gapiza](https://www.longanflange.com/wp-content/uploads/2026/06/图片15.webp) Positioned to serve Brazil’s maritime extraction fields, Gapiza fabricates high-specification components for offshore environments. Thick-walled structural steel and stainless modifications built for offshore rigs and deep-sea mineral processing lines are their core output. Anti-corrosion barrier coatings and automated edge-beveling help field welding crews complete fast, clean installations on offshore exploration decks where conditions make rework expensive. ### **5. Fittings y Llaverías S.A.** **Location:** Santiago, Chile **Founded:** 1968 **Compliance:** ISO 9001, ASV Water Safety Registries ![Fittings y Llaverías S.A.](https://www.longanflange.com/wp-content/uploads/2026/06/图片16.webp) Over five decades in South American metallurgy gives Fittings y Llaverias a level of regional experience that’s hard to match. Their integrated foundry and testing facility runs continuous hydrostatic tests on massive hubbed connections built for seawater desalination operations and heavy municipal aqueducts. Precise phonographic face finishes anchor high-performance gaskets even when temperature changes and seasonal pressure drops put the seal under stress. ### **6. TyP Colombia** **Location:** Bogotá, Colombia **Founded:** 2003 **Compliance:** ISO 9001, ANSI B16.5, ASTM Specifications ![TyP Colombia](https://www.longanflange.com/wp-content/uploads/2026/06/图片17.webp) TyP Colombia serves chemical, petrochemical, and manufacturing networks across the region with robust connection interfaces built on integrated technical machining lines. Precision flange neck tapering and automated bolt-hole alignment keep internal friction low and stop potential leaks along high-pressure oil and industrial processing pipelines. For procurement teams working across multiple South American markets, their multi-industry focus makes them a versatile sourcing option. ### **7. QG Inox** **Location:** São Paulo, Brazil **Founded:** 1989 **Compliance:** INMETRO, Petrobras Quality Baselines, ISO 9001 ![QG Inox](https://www.longanflange.com/wp-content/uploads/2026/06/图片18.webp) With over three decades in Brazil’s industrial piping market, QG Inox produces highly customised connection systems across wide dimensional ranges for chemical, paper, pulp, and beverage sectors where material purity is non-negotiable. Defect-free finishing on weld necks and slip-ons eliminates micro-crevice corrosion, preventing premature failure in facilities handling aggressive, acidic industrial fluids.

Regional food, pharmaceutical, and chemical plants rely on them for components that meet strict sanitary approvals without sacrificing industrial performance. ## **What to Look for in a South American Stainless Steel Flanges Supplier** Procurement in this region comes with variables you may not encounter in other markets. A few things worth checking before you commit to a supplier: - **Regional certification compliance:** For Brazilian projects, INMETRO compliance is often required to clear customs and meet national safety standards. Missing this documentation causes delays that are hard to recover from on a tight schedule - **Material performance for local conditions:** Components used in offshore and mining pipeline systems need to handle deep-sea corrosion and abrasive mineral slurries. Check that your supplier offers duplex, super duplex, or titanium-stabilised grades for these environments - **Logistics capability for large components:** Large-diameter flanges require specialised logistics handling for international shipment, including reinforced crating, anti-corrosion coatings, and experience with oversized breakbulk freight - **Manufacturing tolerances:** High-pressure sealing depends on precision face machining. Suppliers running automated CNC centres deliver more consistent dimensional accuracy across bulk orders Custom Large Diameter Flanges Manufacturer We specialize in manufacturing large diameter stainless steel flanges—custom-made to your specs, forged in-house, and machined with high precision.
