API Standards Objectives Introduction The American Petroleum Institute (API) API API is the main organization of rules and regulations LESER Special for the oil and natural gas industry. Development API 520 API Alloy Concept The API Recommended Practice 520 Special Test Requirements describes recommendations for valve sizing (e.g. nominal coefficients of discharge K d ) Documentation API 526 Conclusion The API 526 standard is an order specification in which „API safety valves“ are defined and Kuwait Reference standardized (e.g. material for body, bonnet, Approvals spring) References API 527 The API 527 standard describes methods How We Serve of determining seat tightness of metal- and soft-seated pressure relief valves. 6 / 15 API Series
What is API Safety Valve ? Objectives Introduction LESER API 526 Series Valves are entirely designed analog to API API API 526. LESER Special Development API 526 has standardized the following Items: API Alloy Concept Orifice designation and area (D to T) Special Test Valve size and pressure rating, Requirements inlet and outlet Documentation Materials Conclusion Pressure-temperature limits Center-to-face dimensions, inlet and outlet Kuwait Reference Sizing independently from manufacturer Approvals Inspection and shop tests References Identification and preparation for shipment Flanged safety valves only How We Serve In addition to API 526 approvals such as UV Stamp, CE or others are required . 7 / 15 API Series
LESER SPECIAL DEVELOPMENT Objectives LESER Competitor LESERs Benefit Introduction Trim Single trim and design for Different parts and Same parts for all services API all services (steam/gas springs for different for easier maintenance and liquid) and options options and services No changes for ASME, LESER Special LESER Special (e.g. bellows, O-ring disc) PED or Chinese AQSIQ Development Development Same setting for all approval services (steam/gas and Less parts reduce spare API Alloy Concept liquid) part stock Special Test Spring Low number of springs for Multiplicity of springs LESER needs only Requirements a fixed set pressure range 13 springs for 15 psig to 1,500 psig (Orifice D) Documentation vs. 39 springs Reduced spring stock for a better spring availability Conclusion Kuwait Reference Approvals References How We Serve
LESER SPECIAL DEVELOPMENT Objectives LESER Competitor LESERs Benefit Introduction Balanced Bellows Balanced bellows Balanced bellows Longer lifetime API are shielded by are fully expose Less shutdown time the bonnet spacer to the flow LESER Special LESER Special in the plant Development Development Designed for 10,000 Designed for 1,000 bellows cycles bellows cycles API Alloy Concept Special Test Requirements Documentation Conclusion Kuwait Reference Approvals References How We Serve
LESER SPECIAL DEVELOPMENT Objectives LESER Competitor LESERs Benefit Introduction Bushing The adjusting screw is Metal spindle is directly Less friction during API equipped with a PTFE in contact with the operation bush adjusting screw Less abrasion of the LESER Special LESER Special spindle Development Development Spindle Design One-piece spindle Two-piece spindle Better alignment API Alloy Concept consists of disc holder Easier assembly and spindle Special Test Simpler design Requirements Lower mass Documentation Spindle Guiding Widely spaced top and Closely spaced guiding Better alignment bottom guide Larger guiding length Less friction at the Conclusion Short guiding length (approx. 2 x disc holder guiding (max. 1,5 x spindle diameter) Kuwait Reference diameter) Approvals References How We Serve
Scope of the LESER API Alloy Concept Objectives Introduction The API Alloy Concept is an extension of the product portfolio that more than API doubles the available material configurations .
