Manufacturing Process of Stainless Steel Pipe Seamless stainless steel pipe is made from solid stainless steel bar which is called billet. By using different processing techniques such as extruding, gun drilling or piercing, the steel bars are produced to be steel tubes.
1. Firstly, the billets would be inspected exactly. |
Austenitic steel
TP304 |
General-purpose stainless steel with good corrosion resistance for most applications. Used for: Bar rails, Boat railings, Canopy supports, Chemical processing equipment, Chemical tubing, Column covers, Duct works, Feed-water tubes, Food preparation equipment, Food processing equipment, Heat exchanger tubes, Hypodermic needles, Ladders, Mechanical & structural components, Pharmaceutical processing equipment, Piping systems, Railings (architectural), Traffic barriers, Water pipes. |
TP304H |
Higher carbon content than 304L, for increased strength, particularly at elevated temperatures. |
TP304L |
Chemical plant and food processing equipment, where freedom from sensitization is required in plate thicknesses TP316/316L |
TP316/316L |
Used where higher corrosion resistance is required. Boat railings, Canopy supports, Chemical tubing, Column covers, Duct works, Feed-water tubes, Food preparation equipment, Food processing equipment, Heat exchanger tubes, Hypodermic needles, Ladders, Mechanical & structural components, Pharmaceutical processing equipment, Piping systems, Railings, Street (urban) furniture, Textile tubing, Traffic barriers, Water pipes. |
TP316H |
Similar oxidation resistance to TP 316. Main areas of application: Heat exchangers, furnaces, chemical and petrochemical plant. |
TP321 |
Heat exchanger tubing, Chemical processing tubing, Pressure tank tubing. Suitable for heat resisting applications to 800°C. |
TP321H |
This is the high carbon version of TP 321 which ensures greater creep resistance. Behaves much the same as TP 321 in oxidation resistance. Main applications: Heat exchangers, furnaces, boilers in chemical and petrochemical plant |
TP316Ti |
A titanium stabilized version of 316 used where good resistance to intergranular corrosion and high temperature strength is required. |
TP317 |
Chemical processing tubing, Dyeing equipment, Ink manufacturing equipment, Pulp & paper manufacturing equipment |
TP347HFG |
Mainly used for boilers in the termal power plant, reheaters and superheaters |
Super-Austenitic steel
TP904L High resistance to general corrosion in e.g. sulphuric and acetic acids, crevice corrosion, stress corrosion cracking, pitting in chloride bearing solutions. |
Ferritic and Martensitic Steel
TP405 |
Used for applications where hardening upon cooling from high temperatures must be avoided. Has excellent long-time stability up to 1200°F. |
TP410 |
General purpose grade for use in mildly corrosive environments |
TP430 |
Mechanical & structural tubing, Architectural tubing, Heat exchanger tubing, Condensers, Re-heaters, Evaporators. |
Duplex
S31803 |
Typically used in heat exchangers, gas scrubbers, fans, chemical tanks, flowlines, marine and refinery applications. |
S32750 |
Used in oil & gas, chemical process, power industries. At that heat-exchangers are main application. |
S31254 |
With high levels of chromium, molybdenum, and nitrogen is especially suited for high-chloride environments such as brackish water, seawater and other high-chloride process streams. |
