Stainless Steel Seamless Tube ASTM A269 TP304 1.4301 Oil and Gas
The ASTM A269 TP304 is an austenitic grade of steel that covers standard seamless and welded configurations. The ASTM A269 TP304 Tube is designed with a superior composition of nickel and chromium with other constituting alloys, giving these tubes enhanced resistance against corrosive and oxidative media.
ASTM A269 Tp304 Stainless Steel Tubing has a density of 8 g/cm³ with a melting point of 1400 degrees C. These tubes has excellent mechanical properties and can work well in different pressures and temperatures.
The maintenance methods of TP304 stainless steel seamless pipe:
①TP304 stainless steel seamless pipes should be stored in a clean and ventilated environment, and the outer packaging should not be opened at will during storage.
②Be careful when adding padding paper. If the outer packaging of TP304 stainless steel seamless pipe is accidentally soaked, the padding paper should be removed immediately to prevent rust.
③TP304 stainless steel seamless pipes should be protected from direct light and should be replaced in time if the film deteriorates.
④When storing TP304 stainless steel seamless pipes, attention should be paid to moisture, oil, lubricants, etc. to avoid causing rust in the long term.
