304 Stainless is a low carbon (0.08% max) version of basic 18-8 also known as 302.
Type 316 is more resistant to atmospheric and other mild environments than Type 304.
310S Stainless Steel has excellent resistance to oxidation under constant temperatures to 2000°F.
317L is a molybdenum bearing austenitic chromium nickel steel similar to type 316, except the alloy content in 317L is somewhat higher.
Alloy 321 (UNS S32100) is a titanium stabilized austenitic stainless steel with good general corrosion resistance.
Type 410 is a martensitic stainless steel which is magnetic, resists corrosion in mild environents and has fairly good ductility.
ASTM A213 ASME SA-213 TP347H Seamless Steel Tubes contains NB-Cr-Ni austenitic stainless steel.
Duplex 2205 (UNS S31803), or Avesta Sheffield 2205 is a ferritic-austenitic stainless steel.
Duplex 2507 (UNS S32750) is a super duplex stainless steel with 25% chromium, 4% molybdenum..
Material to UNS S32760 is described as a super duplex stainless steel with a microstructure of 50:50 austenite and ferrite.
ASTM A269 / A269M Standard Specification for Seamless and Welded Austenitic Stainless Steel Tubing for General Service
ASME SA 249 Standard Specification for Welded Austenitic Steel Boiler, Superheater, Heat-Exchanger, and Condenser Tubes.
904L stainless steel consists of chromium, nickel, molybdenum and copper contents, these elements give type 904L...
It refers to the state of final plastic deformation or final heat treatment of the delivered product. The hot-rolled or cold drawn (rolled) state or manufacturing state generally delivered without heat treatment; the heat-treated state after heat treatment delivery, or the normalizing, tempering, solid solution, annealing according to the type of heat treatment status.
| Delivery status | Abbreviation | Description |
| Cold-finished/hard (cold-finished as-drawn) | BK | No heat treatment after the last cold-forming process. The tubes therefore have only low deformability. |
| Cold-finished/soft (lightly cold-worked) | BKW | After the last heat treatment there is a light finishing pass (cold drawing) With proper subsequent processing, the tube can be cold-formed (e.g. bent, expanded) within certain limits. |
| Annealed | GBK | After the final cold-forming process the tubes are annealed in a controlled atmosphere or under vacuum. |
| Normalized | NBK | The tubes are annealed above the upper transformation point in a controlled atmosphere or under vacuum. |
Silicon carbide, mainly consisting of SiC, also known as carborundum, is a hard chemical compound containing silicon and carbon.
Rare earth alloy wear-resistant pipe has the characteristics of fast velocity and high flow rate.
The ceramic sleeves lined pipe as a whole part, and then assemble it into the steel pipe with our high-strength-temperature-resistant epoxy adhesive.
Ceramic tile lined pipe and Bend are cast with mold vanishing vacuum suction casting cladding process.
Cast basalt is a kind of silicate crystalline material after producing and processing
Ceramic lined pipe is made through self-propagating high-temperature synthesis (SHS) technique.
Bimetal clad pipe is cast with mold vanishing vacuum suction casting cladding process.
Tubes Erosion Shields are used to protect boiler tubing from the highly erosive effects of high temperatures.
UHMWPE is well suited for pipe applications that demand high abrasion resistance combined with low friction.
Ceramic lined pipe is made through self-propagating high-temperature synthesis (SHS) technique.
Cast basalt lined steel pipe is composed by lined with cast basalt pipe, outside steel pipe and cement mortar filling between the two layers.
Ceramic tile lined pipes have very uniform coating of specially formulated ceramic material that is affixed to the inner of the pipe.
The material of the rare earth alloy wear-resistant pipe is ZG40CrMnMoNiSiRe, which is also the grade of rare earth alloy steel.
Tubes Erosion Shields are used to protect boiler tubing from the highly erosive effects of high temperatures and pressures thereby greatly extending tube life.
The ASTM A213 T91 seamless tubes are primarily used for boiler, superheater, and heat-exchanger.
