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.

Manufacturing process

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.

2. Then put the billets into the heat to raise the temperature.

3. The hot billets would then be pierced through the center with a mandrel. Through this procedure, the bar shape billet becomes hollow shape billet.

4. The next step is rolling and stretching the hollow billet. The billet is precisely rolled and stretched until it meets all the specifications with length, diameter and wall thickness according to requirements.

Application

Stainless steel seamless pipe can resist high temperatures for cleanliness and maintain the purity of materials which contact stainless steel directly. Stainless steel pipe and tubing are used in chemical plants, aviation fields, marine equipment, cryogenic transportation, medical and architectural industries.
