Applications
1.Sealing of reaction pipelines in refinery catalytic cracking units.
2.End closure of high-temperature and high-pressure steam pipelines in power plants.
3.Export process pipelines complying with ANSI/ASME standards.
4.Temporary closed end for pigging operations in long-distance natural gas pipelines.
Product Advantages
Clear Standard System
The dimensions and tolerances of asme caps are strictly in accordance with ASME B16.9, facilitating procurement for international engineering projects.
01
Complete Pressure Ratings
Asme caps are available in various wall thickness grades corresponding to different pressure ratings. Users can select flexibly according to the pipeline design pressure.
02
Dense Forging Process
Socket-weld and threaded ASME Caps are mostly formed by die forging with complete metal flow lines and no internal casting defects, suitable for high-pressure working conditions.
03
Strong Material Traceability
Each batch of ASME Caps complies with ASTM material standards. Chemical composition and mechanical properties can be traced via heat treatment records and material test certificates.
