I am looking for some companies who can supply the raw material for making viscoelastic foam. My client has approached several chemical suppliers such as Bayer and other, but they would also like to see the possibility of getting the system from other manufacturer preferably based in America...
I am doing some study on the design of direct fired oil heater for refinery used.
Can anybody explain what is the main differences between a heater designed according to ASME standard compare to API Standard.
Thanks.
DA
