Backpack Elbow
Wear resistant alloy backpack elbow for complex slurry conveying and discharge systems.
15NiCuMoNb5 is a low alloy steel that contains Nickel, Copper, Molybdenum, and Niobium as its primary alloying elements.
15NiCuMoNb5 is commonly used in the manufacturing of pressure vessels, boilers, and piping systems for the power generation and petrochemical industries, due to its high strength, toughness, and resistance to corrosion and high-temperature environments.

Note: WB36 (15NiCuMoNb5) is a fine-grain quenched and tempered low-alloy steel developed for high-pressure boiler drums and thick-walled pressure vessels. Values apply to normalized and tempered condition per EN 10028 / VdTÜV Material Data Sheet 377.
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.
