Elbow manufacturers summarize the performance comparison of national standard 90 degree elbows

In piping systems, 90-degree elbows are fittings that change the direction of a pipe. They are one of the most commonly used elbow fittings in pipeline engineering, accounting for approximately 80% of all elbows. 90-degree elbows are made from materials such as cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals, and plastics. National standard 90-degree elbows are those produced according to national standards, including GB12459 "Steel Butt-Weld Seamless Pipe Fittings," GB/T14383 "Forged Steel Socket-Weld Pipe Fittings," GB/T14626 "Forged Steel Threaded Pipe Fittings," and GB/T13401 "Steel Plate Butt-Weld Pipe Fitt

Advantages and disadvantages of slip-on flanges

Slip-on flanges are a common flange type. During installation, the pipe is inserted into the flange's inner hole and secured with a fillet weld. Due to its simple structure and relatively low price, it is widely used in low-pressure piping systems. Below, I summarize the main advantages and disadvantages of slip-on flanges:
