FAQ
316 stainless steel pipe is a type of stainless steel pipe that is made from grade 316 stainless steel. Grade 316 stainless steel is a high-quality, corrosion-resistant alloy that contains chromium, nickel, and molybdenum. It offers excellent resistance to corrosion, including pitting and crevice corrosion, making it suitable for various applications in industries such as marine, chemical processing, and pharmaceutical.
As trusted stainless steel pipe suppliers, we provide high-quality 316 stainless steel pipes that meet industry standards and specifications.
Stainless steel pipe is known for its excellent corrosion resistance, which helps prevent rusting. The presence of chromium in stainless steel forms a protective layer called the passive film or oxide layer. This film acts as a barrier, preventing oxygen and moisture from reaching the underlying metal surface and causing corrosion.
However, it’s important to note that stainless steel is not entirely immune to rust. In certain extreme conditions, such as prolonged exposure to highly corrosive environments or improper maintenance, stainless steel pipes may experience localized corrosion or surface staining. This is commonly known as “tea staining” and can occur when the passive film is disrupted.
The production of stainless steel welded pipes usually goes through the following steps:
Material Preparation: Select suitable stainless steel coil as raw material. Commonly used stainless steel materials include 304, 316, etc.
Coil Unrolling: Stainless steel coil is unrolled into a strip material of certain width by coil unrolling machine.
Cutting: The unrolled stainless steel strip is cut according to the required length to get the required pipe length.
Bending and Forming: The cut stainless steel strip is bent and formed into a round tube using equipment such as bending machines and tube coiling machines.
Welding: The two ends of the pipe are butted together and then welded by welding techniques such as TIG (argon arc welding) or MIG (gas shielded welding) to join the two ends into one.
Cold-Drawing or Cold-Rolling: The welded tubes are cold-drawn or cold-rolled to give them precise dimensions and improve their surface finish and mechanical properties.
Cleaning and Surface Treatment: After welding and forming, stainless steel welded tubes need to be cleaned and surface treated to remove oxides and impurities produced during welding and to improve their appearance.
Professional stainless steel pipe suppliers usually follow strict fabrication processes and quality control to ensure the provision of high quality stainless steel welded pipe products.
The following are some common maintenance and care methods for stainless steel pipes:
Regular Cleaning: Use mild detergent and a soft cloth or sponge to clean the surface of stainless steel pipes. Avoid using cleaners containing chlorine ions to avoid corrosion of stainless steel.
Avoid Scratching: Try to avoid using hard brushes, abrasives or rough cleaning tools to clean the stainless steel tube to avoid scratching its surface. Use soft brushes or sponges for cleaning.
Remove Stains: For more stubborn stains, use diluted vinegar or lemon juice for cleaning. Apply the cleaner to the stain, let it sit for a few moments and then rinse with water.
Prevent Salt and Chemical Build-Up: Avoid prolonged exposure of stainless steel pipes to salt water, chemicals or strong acid and alkali solutions to avoid corrosion.
Regular Inspection: Regularly check the surface of the stainless steel tube for scratches, damage or signs of corrosion. If problems are found, promptly take repair measures to prevent further damage.
Prevent the Accumulation of Foreign Objects: Stainless steel tubes should avoid prolonged contact with organic matter, dust and impurities to avoid contamination and corrosion.
Pay Attention to Storage: When storing stainless steel tubes, they should be kept dry and ventilated to avoid contact with moisture or corrosive substances.
Regular Polishing: According to the need, polish the stainless steel tube regularly to keep its surface bright and clean.
