API Std 600


API Std 600, also known as API 600 or ASME B16.34, is a widely recognized standard in the non-destructive testing (NDT) industry. It pertains specifically to the design and manufacturing of steel gate, globe, and check valves for petroleum and natural gas industries. Compliance with this standard ensures that these valves meet the required quality and performance criteria. NDT and PWHT Solutions, a renowned company in the field, has established itself as a leader in delivering NDT services in accordance with API Std 600, offering exceptional expertise and reliability.

API Std 600 Overview:

API Std 600 is published by the American Petroleum Institute (API) and is widely accepted as a benchmark for gate, globe, and check valves used in the oil, gas, and petrochemical sectors. The standard outlines the requirements for valve materials, design, manufacturing, testing, inspection, and documentation. By adhering to API Std 600, valve manufacturers can ensure the integrity, safety, and reliability of their products.

Key Features of API Std 600:

Materials: API Std 600 specifies the acceptable materials for valve components, ensuring they meet the required mechanical properties, corrosion resistance, and other material characteristics necessary for the harsh conditions encountered in the oil and gas industry.

Design and Manufacturing: The standard defines the design criteria for gate, globe, and check valves, including dimensional requirements, wall thickness, pressure-temperature ratings, end connections, and face-to-face dimensions. It also addresses manufacturing processes, such as casting, forging, and heat treatment, ensuring valves are manufactured to the highest standards.

Testing and Inspection: API Std 600 outlines rigorous testing procedures that valves must undergo to ensure their integrity and performance. This includes hydrostatic testing, shell and seat leakage testing, and other critical inspections to verify compliance with pressure and leakage requirements.
