Hi
We are looking at the requirement to use antistatic utility air hoses in offshore applications, typically 1/2 and 3/4 inch air hoses at 1MPa. Our internal standards call for antistatic hoses but the antistatic requirement is being challenged.
The literature read so far does not...
Dear All
We have a number of utility boilers of varying ages and are in the process of rationalising boiler tube stocks. I would like your opinions on the most commonly used boiler tube standards. The ones we are currently considering are:
ASTM standards (A192,A209,A213)
ISO standards...
Hi
We have experimented with various materials for valve spindles operating in steam at 540C including
Nitrided low allow steels (EN41B)
Nitrided 12Cr steels
Incolloy 800 HT
The most successful valve spindles have been a low alloy steel (AISI P20) coated with Stellite 6. We wish to...

Dear all
We have a CrMoV turbine casing with a large crack (35 mm depth). We have come to the conclusion that we do not want a full weld repair because of distoration concerns. We believe that it would be acceptable to leave the crack in situ as it is below the crical size.
The cracking is...
Dear all
We have a steam turbine nozzle block that is made from a martensitic stainless steel (similar to 422). The nozzle assembly is fabricated from individual nozzles which are welded together. The weld material is a nickel based alloy believed to be Inconel 182.
We are currently...
