Projects
Many years of large-scale project experience in various fields（Oil & Gas, Construction, Power Energy, Marine & Offshore, Water Treatment, Exploration & Drilling Services, Pipeline & Petrochemical etc.）, professional project team is responsible from receiving until the end of the project.
Pipe pressure rating: usually determined by a common pipe fittings standard nominal pressure rating and wall thickness of the pipe pressure rating that can reflects the parameters characteristic called pipe pressure rating. The customary to simplify the description, often to the pipe fittings nominal level called pipeline pressure rating. Pressure levels to determine the basis for the design pressure of the pipeline, but also the core design. It is the pressure piping, pressure piping design stress check preconditions pressure pipeline is an important factor in investment in infrastructure and pipeline reliability impact.
Seamless steel pipe(smls pipe) pressure
Composed piece of seamless steel pressure pipes are generally standard, so the pressure piping components are primarily designed selection, pipeline pressure levels to determine their standard of its standard level is determined.
