Tests
100% tested according to API STANDARD 598. Each manifold is tested to check the leakage in the seats and packings. Under request, the corresponding materials and test certificates can be delivered with the manifold. Packaging
All TECVAL manifold are supplied packed in individual polyethilene airtight bags. End screw connections are protected with polyethilene caps. Everything is 100% recyclable. Maintenance Adjustment of the packings may be necessary during the working life of the manifold. The operation consists of turning the nuts (3) clockwise. Manifolds with long no-working period may have a harder initial operating torque. |
