The supplier reports a 52,000 m² plant, 10 production lines, annual casing-centralizer output of 200,000 pieces, and exports to multiple global regions. ISO 9001:2015, ISO 14001:2015, and ISO 45001:2016 are stated, while other company information references API certifications. Trade records show shipments associated with buyers in India, Brazil, and Peru, but the records are recent and limited. Evidence supports established manufacturing and export capability; after-sales service, financial credibility, and customization capability remain insufficiently documented.

Client casesThe supplier is associated with buyers or shipments involving VNK Solutions, Smart Welding de Macae Servicos Ltda, and a Peru-related transaction, while also stating exports to more than 30 countries.
