Product Description
2205 welded stainless steel pipe
Duplex 2205 is a two-phase, ferritic, austenitic 22% chromium, 3% molybdenum, 5 to 6% nickel alloyed stainless steel. It is the most widely used duplex stainless steel grade and is characterized by high yield strength, double that of the standard austenitic stainless steel grades. It also demonstrates good fatigue strength, as well as outstanding resistance to stress corrosion cracking, crevice, pitting, erosion, and general corrosion in severe environments.
APPLICATIONS:
Chemical processing, transport and storage – pressure vessels, tanks, piping, and heat exchangers
Oil and gas exploration and processing equipment – piping, tubing, and heat exchangers
Marine and other high chloride environments
Effluent scrubbing systems
Pulp and paper industry – digesters, bleaching equipment, and stock-handling systems
Cargo tanks for ships and trucks
Food processing equipment
Biofuels plants

FAQ
Q1: What is your major market?
A1: 95% of our tubes export. We mainly sell to America, Canada, Australia, Japan, Russia, Germany, France, Dubai, Brazil, Chile, India, Thailand, South Africa, Egypt, Nigeria, etc.
Q2: What's the annual output?
A2: We can produce more than 21,000 tons stainless steel tubes in a year.
Q3: What is your welding method?
A3: All of our tubes are welded by TIG welding methods. Our tubes can get fully welding and smooth inner welding, without blisters, leak welding or black line. All of our tube are good for tube bending.
Q4: How do you control the quality during the polishing process?
A4: 1)As for the mirror polish square/rectangular tube, we will polish it as least four times.
2)During the polishing processing, we set a special sanding wheel to polish the welding part.
3)To avoid scratches, after polishing, the tubes will be lay out on a steel crate then we could lift the whole steel crate instead of the tube.
4)On the other hand, we use the gunny bags to protect the tube's surface when the tube laying-out.
Q5: How do you inspect the tubes?
A5: The Quality inspectors inspect the tubes during each production processes from raw material, tube welding, polishing, packaging.
1) Before the production of each machine, we will have the first checked and record the data.
2) During the production, our inspector and engineer have been carefully moniting and we record the data every two hours.
Q6: What is the MOQ?
A6: 2ton.
Q7: What’s the delivery time for the tubes normally in your company?
