ASME SA516 Gr. 70 Tubesheet Plates For Heat Exchanger , Placa Caldera
YUHONG Group can do many projects: heat exchanger / boiler projects, marine projects, oil & gas projects etc.And we supply variety of tube sheets made by many materials, such as of carbon steel, stainless steel, copper steel and alloy steel!
This page is about ASME SA516 Gr. 70 carbon steel tube sheet baffle plates for heat exchanger, for boiler, etc.
We are konwn that tube sheet is a plate that is used to support and hold the tubes in various heat exchangers, boilers, and other types of equipment where tubes are used. It is an important component in heat exchangers and boilers.The tube sheet is typically made of a metal and has holes or openings drilled into it to allow the tubes to pass through. The tubes are then secured to the tube sheet by various methods such as welding, rolling, or expansion.
ASME SA516 This specification covers carbon steel plates intended primarily for service in welded pressure vessels where improved notch toughness is important.
Plates under this specification are available in four grades having different strength levels as follows:
Grade 55 ; Grade 60 ; Grade 65 ; Grade 70
Chemical Composition (%) Grade 70
