What Are SMO 254 Pipes?

SMO 254 pipes are corrosion-resistant high alloy stainless steel tubes constructed primarily of chromium, nickel, molybdenum, and nitrogen that boast exceptional resistance against both generalized corrosion as well as localized pitting in acidic environments including seawater, acid solutions and chlorides-containing media such as seawater. SMO 254 is widely utilized by chemical processing, pulp & paper production as well as offshore oil & gas exploration due to their exceptional resistance properties as well as high strength making them suitable for many demanding applications where reliability & durability play an integral role such as chemical processing & paper production or offshore oil and gas exploration where reliability/durability are of primary concern.

Manufacturing Process Of SMO 254 Pipes

Rolling and Welding

The strips pass through the number of rollers as per the required size. In the tubes-mill, the strip is gradually converted into the tubular shape. The fitted welding machine is then used to weld trim edges of the strip using TIG welding process.

Length Cutting

Rolled pipes and tubes thus manufactured are cut to the required lengths depending upon the industrial demand. We use a variety of methods—sawing, lathe cutting, rotary cutting, supported shear cutting, dual-blade shear cutting, and laser cutting.

Cleaning and Heating Phase

Subjected to cleaning to remove the dirt. Further, a heat treatment is given to these rolled pipes and tubes to remove the stresses that may occur due to welding and formation processes. Heat treatment is given on the continuously rolling hearth furnace.

Cold Drawing Process

Required size may not be obtained from the mill directly. Then, the cold operation process can be used to obtain the desired size. In the cold drawing process, the tube or pipe is drawn over the bench using Die plugs.

Finishing Process

Pipe and tubes are then subjected to cleaning, heat treatment, pickling and straightening. The computerized ink jet marking machine then mark the finished pipes or tubes. Then they marked with grade of material, size, heat number.
