ⅠReply for material

A. Pipe material:We have adopted ASME standard material for the pressurized parts of boiler( mandatory parts in Section 1

of ASME code),boiler external pipeline ( in the scope of ASME B31.1)and the main steam pipeline( not in the scope of

ASME) and the Inspection Agency have been engaged to inspect the pipeline material( ABS Shanghai) .But for the

other pipeline in boiler and process pipeline,we use GB standard material and also invite ABS to issue acceptance

certificate and stamp the related material designation of ASME .The main GB material and corresponding equivalent

ASME material are listed in the follwing table.In China, material substitution of the corresponding equivalent material

is allowed.But for the DIN standard,we ‘re not familiar with it because we don’t use DIN standard normally,but we also

list the contrast table of different standards for your reference. And you can also find the corresponding info on line.

B，We adopt GB standard for the other steel material,such as material of plate,which is also included in the following

contrast sheet.

C. For the chemical component,mechanism performance of pipe,we only have one original.so we can’t provide it

now.But We can provide one copy to you in the second liaison at Wuhan in China.

Note:

This contrast table is based mainly on the closely chemical component and equivalent mechanics performance .

Ⅱ About the Quality Inspection Plan,we now can’t provide you the detailed inspection plan for SFI project because we’re

now in the stage of manufacturing design( see the attachment 1).So now we provide a universal ABS inspection plan to

you.Then after the design finished,we will provide a detailed supervision plan to you. 6

Ⅲ,About the revised flow chart,we are now having an liaison with our design institute ,so we will provide a confirmed info

to you around Nov 15.
