API Compliant Diaphragm Coupling
API Compliant Diaphragm Coupling (DTE Type)
Product Identification
API Compliant Diaphragm Coupling - DTE Type | Keywords: API Certification, Petrochemical Special, Temperature and Pressure Resistance
Core Value: Strictly designed and manufactured in accordance with API 610 petrochemical industry standards, the API compliant diaphragm coupling has excellent temperature and pressure resistance, corrosion resistance, adapts to harsh working conditions in the petrochemical industry, and provides safe and reliable transmission guarantee for key equipment such as pumps, valves and compressors.
Core Advantages
The API compliant diaphragm coupling has passed API 610 standard certification, meeting the strict requirements of the petrochemical industry for transmission equipment, and can operate for a long time in high temperature, high pressure and corrosive environments.
The main body is forged from high-strength alloy steel, strengthened by heat treatment, with high tensile strength, capable of bearing heavy loads and impact loads.
The diaphragms are made of multi-layer 301 stainless steel, with uniform elastic deformation, strong deviation compensation ability and high transmission accuracy.
The sealed structure design effectively isolates oil and gas, dust and other impurities, with a protection level of IP65.
Material and Process
The main body is 42CrMo alloy steel, the diaphragms are 301 stainless steel, the shaft sleeves are subjected to carburizing and quenching + precision grinding process, the surface is subjected to rust and corrosion prevention treatment, and all welds are subjected to non-destructive testing to ensure structural strength.
Application Scenarios
Mainly used in petrochemical, natural gas, oil refining, coal chemical and other industries, suitable for transmission systems of key equipment such as pumps, valves, compressors, fans and centrifuges. The API compliant diaphragm coupling can withstand working temperatures of -40~150℃.
Installation and Maintenance
