Stainless Steel is the first choice for usage on oil platforms
Stainless steel structural sections for oil platforms. The major part of structural sections in stainless steel that engineers plan for the topside of off-shore rigs are square and rectangular hollow sections. They are followed by U channels and angle bars, generally equal leg angles.
Stainless Steel Wire Mesh Screens & Products - TWP Inc.
Stainless steel mesh can be cut with scissors to diameters from .001 inch to .010. Tin snips are needed for heavier wire diameters from .011 up to about .047. Wire diameters over .047 inches are difficult to cut with hand tools, but a compound aircraft-style hand shear can usually handle the task.
Pipe Inspection,Testing & Marking Requirements to Ensure ...
Pipe Inspection – Hydro Test, NDT, Visual and Dimension. To ensure product quality, during and after the production certain pipe inspection and non-destructive testing are performed on the body & weld of the pipe. These pipe inspection will check whether any physical defects are present in the pipe/weld, which may affect its performance ...
Bolt Depot - About Thread Galling
Thread galling occurs during installation when pressure and friction cause bolt threads to seize to the threads of a nut or tapped hole. It is also known as " cold welding ". Once a fastener has seized up from galling it is typically impossible to remove without cutting the bolt or splitting the nut.

Placing Reinforcing Steel| Concrete Construction Magazine
13-03-2005· Reinforcing steel must be secured to prevent displacement during construction activities and concrete placement. This is usually accomplished with tie wire. Tie wire comes in 3- or 4-pound coils. Wires are placed in a wire holder or a reel is suspended from the worker's belt for accessibility. The wire is typically 16½ - or 16-gauge black ...
THE ROLE OF STAINLESS STEELS IN PETROLEUM REFINING
The applications for stainless steels in petroleum refining are many and varied. The purpose of this booklet, therefore, is to help materials engineers identify those applications and to provide data to support the use of stainless steels in the high-temperature, corrosive environments that may be encountered. The stainless steels described in this
GMAW vs FCAW-S Process - Lincoln Electric
You most likely are very comfortable building things from wood, but you always wanted to step up to steel. You probably want to run it off of 115 volt input, so that it is very portable, but maybe stepping up to the 230 volt input machines with the option of welding thicker material (more than ¼") is a valid point.
