Stainless Steel Pipe TP-304/304L is an excellent choice for its tensile strength, high resistance to corrosion, and temperature resistance. With the ability to be sterilized, 304/304L stainless steel pipe is a cost-effective choice for most applications such as moving liquids and gases in temperate and corrosive conditions. 


Application:
 Household Utensils (sink, interior pipe, ht-water system, bathtub, boiler and others), 
 Automotive Components (wipe, muffler, molding), Medical Instruments, Building Materials, 
Industries (chemical, food processing, textile) and vessel parts. 


Storing:
 Stainless steel has good corrosion resistance due to the oxidized layer on the surface. Therefore, careful attention should be paid to maintain the oxidized layer in good condition.
 It is important to store stainless steel away from moisture, dust, grease and lubricant in order to protect its surface from rust and lowered corrosion resistance when welding.
 When moisture penetrates between stainless steel and protective film, the corrosion develops faster than it does without protective film.
 It is strongly recommended to store stainless steel in a clean, dry and well ventilated place preferably in the original package with an additional cover.
 The protective film should not be directly exposed to sunlight, and the film should be inspected regularly. If the film shows signs of deterioration (film lifespan is approx. 3 months), it should be replaced immediately. When packaging materials including insent paper get wet, they should be immediately removed to prevent surface corrosion.
