Request a copy of the manufacturer’s API 6D certificate (issued by an accredited body like API or DNV). Additionally, ask for the latest “Product Specification Level” (PSL) test reports. At Thriveon, we provide the full certification package including design verification, shell test, seat leakage test, and material traceability for every valve.

Standard sizes (2″–12″, Class 150–600): 35–45 working days. Larger sizes or higher pressure classes (Class 900–1500): 45–55 working days. Express service available for urgent orders – contact us with your required date.

Every valve undergoes a documented inspection plan: material verification, dimensional check, hydrostatic shell test (1.5x rated pressure), pneumatic seat test (1.1x), and visual inspection. Customers can also request third‑party inspection (SGS, BV, Lloyds) at our cost for orders above $50,000.
