ASTM A105 tee corrosion and heat resistance
These sturdy fittings connect the piping and other components at a 90-degree angle. An ASTM A105 tee resembles the English letter “T” and is known for moderate to good corrosion resistance in pressure systems. This property stems from its chemical composition: nickel, chromium, and also molybdenum. It can resist pitting, crevice corrosion, and stress-induced cracking.
The heat resistance of the material is also satisfactory. An ASTM A105 lateral tee can withstand high temperatures. It can operate at temperatures from -29 to -450°C. This material undergoes forging at around 2200°F and subsequent heat treatments, like quenching and normalizing.
What is the extrusion method for manufacturing an SA105 equal tee?
Manufacturers produce equal tees with two outlets at 90 degrees and one primary connection. The extrusion method for an SA105 equal tee uses raw material with greater diameters than the desired tee. The component gets pushed or extruded from the pipe, the body undergoing pressing at the time. This method can produce tees of different wall thicknesses but is better for small to medium sizes.
The mandrel method is also a popular production technique for these fittings. An ASME SA105 forged tee produced by hot forming can be production-efficient and defect-free for varied applications.
What are the disadvantages of A105N unequal tee annealing?
Annealing is a popular heat treatment to enhance the chemical and mechanical properties of the material. An A105N unequal tee (normalized for use in low temperatures) can undergo annealing to meet specific characteristics. The process involves cooling to below 1000°F and reheating to 1700°F. The final step is slow cooling in a furnace. However, annealing can incur some disadvantages, so you should weigh it with caution.
