Effective as of March 15, 2025
This document sets forth the specific definitions, disclaimers, and conditions that govern the interpretation of all technical specifications, performance claims, and contractual obligations related to Vergotamexicana’s heavy extrusion and high-pressure piping products. These clarifications are intended to prevent ambiguous readings and ensure that all parties share a precise understanding of material tolerances, testing protocols, and liability limits.
All references to “micrometric tolerance,” “high-pressure rating,” or “structural reinforcement” are based on standardized laboratory measurements under controlled conditions. Actual field performance may vary depending on installation, operating environment, and maintenance practices.
Vergotamexicana performs routine non-destructive testing (ultrasonic, magnetic particle, and hydrostatic) on all pressure-rated products. Certificates of compliance are issued per batch, not per individual unit, unless expressly requested and documented in the purchase order.
Surface roughness values (Ra ≤ 0.8 μm) are measured on representative samples from each production run. Corrosion protection treatments (galvanizing, epoxy coating) are applied according to customer specifications and do not constitute a warranty against all forms of corrosion under aggressive chemical or saline exposure.
Vergotamexicana’s liability for any claim arising from the use of its products is limited to the replacement of the defective product or a refund of the purchase price, at the company’s sole discretion. Under no circumstances shall Vergotamexicana be liable for consequential damages, including but not limited to loss of production, downtime, or injury to personnel.
This document is originally drafted in English. In the event of any discrepancy between the English version and a translation, the English version shall prevail. All disputes arising from or related to these clarifications shall be resolved under the laws of the Argentine Republic, with exclusive jurisdiction in the courts of the City of Buenos Aires.
Proceso de laminado a temperaturas controladas que garantiza espesores de pared con tolerancias de ±0.03 mm en perfiles estructurales y tubos de hasta 12 metros de longitud.
Reducción de pérdidas por fricción en circuitos hidráulicosLínea de trefilado en frío con capacidad de reducción de hasta 6 mm por pasada, logrando acabados superficiales Ra 0.6 μm en barras de acero al carbono SAE 1045 y 1020.
Eliminación de tensiones internas en componentes críticosMáquinas punzonadoras de 200 toneladas que realizan perforaciones y rebajes en tubos de pared gruesa sin deformar el diámetro interior, manteniendo la concentricidad dentro de ±0.05 mm.
Integridad estructural en puntos de unión sometidos a presiónBanco de pruebas con capacidad de presurización hasta 600 bar, complementado con inspección ultrasónica phased array para detección de inclusiones y laminaciones internas.
Certificación de cada lote según norma ASTM A53 / API 5LLínea de galvanizado en caliente con inmersión controlada que aplica capas de zinc de 85 a 120 μm, más pintura epóxica de acabado para ambientes con alta humedad o exposición química.
Vida útil extendida en instalaciones industriales exterioresAnálisis de elementos finitos para optimizar la geometría de refuerzos internos en vigas y perfiles, logrando incrementos de hasta un 40% en el módulo de sección sin aumentar peso.
Distribución uniforme de tensiones en puntos críticos de cargaOur engineers analyze your pressure and load specs, material grade, and dimensional tolerances. We confirm the exact carbon steel alloy and heat treatment cycle before any tooling is prepared.
Billets are heated to 1200°C and passed through our reversing mill. For tubular products, a piercing mandrel creates the hollow section under strict temperature control to avoid internal defects.
Rolled profiles are drawn through tungsten carbide dies at controlled speed. Each pass reduces cross-section by 8–12% while maintaining ±0.02 mm on critical diameters. Lubrication is phosphate-based.
Every tube and bar undergoes full-body ultrasonic scanning for laminations and inclusions. Hydrostatic pressure tests are run at 1.5× the rated working pressure with hold times of 30 seconds minimum.
Finished parts receive either hot-dip galvanizing or two-coat epoxy paint. Threaded ends are protected with steel caps, and bundles are strapped with anti-corrosion paper for shipment.
