Re: [MW:4886] fire fighting piping system design

By Materials & Welding

Hi Danial,

What is the problem your facing for routing the FF line under ground or above ground.Only NFPA gives Guide line for designing the system.There is no such standards for routing the line above ground or underground.

But only the thing you need to care is insulating flange if your network is having cathodic protection.Routing the line above ground or underground you need to fallow the client specification and requirement.If you have parallel underground lines running together then you need to think about line spacing requirement for maintenance.

If you have any specific problem please send it to me.Then i can give you some information to solve the problem.

Other than that there is no problem for routing line above ground or below ground.

Regards,

Hello,
 
I have a situation.......our contractor build the fire fighting network inside the Farm of gasoil tanks ......a part underground (how it was in initial project) and part above the ground.....
 
My opinion it was to left the piping underground......
 
Anyone can tell me what code or specs show the position(above or underground) of fire fighting system inside the farm......(or safety regulation....)
 
whats your opinion...?
 
Regards

Heat tint (temper) colours on stainless steel surfaces heated in air // Heat tint

By Materials & Welding
Introduction The colour formed when stainless steel is heated, either in a furnace application or in the heat affected zone of welds, is dependent on several factors that are related to the oxidation resistance of the steel. The heat tint or temper colour formed is caused by the progressive thickening of the surface oxide layer and so, as temperature is increased, the colours change.   Oxidation resistance of stainless steels However, there are several factors that affect the degree of colour change and so there is no a single table of colour and temperature that represents all cases. The colours formed can only be used as an indication of the temperature to which the steel has been heated. Factors affecting the heat tint colours formed Steel composition The chromium content is the most important single factor affecting oxidation resistance. The higher the chromium, the more heat resistant the steel and so the development of the heat tint colou...
