Generally also contain small amounts of silicon, manganese, sulfur, phosphorus and carbon steel, in addition to carbon use can be divided into carbon steel and carbon structural steel, carbon tool steel, and ease of cutting structural steel three categories. Carbon structural steel is divided into building structural steel and machinery manufacturing structural steel two kinds.
Although machinable, the high strengths of these Carbon Steel Elbow Butt Weld Pipe Fittings make machining difficult. As an example, machining of our Carbon Steel Tee Butt Weld Pipe Fittings is around 20 % slower than for stainless steel. These Carbon Steel Cross Butt Weld Pipe Fittings cannot be hardened by heat treatment, which further can however be work hardened. Solution treatment or annealing of our Carbon Steel Reducer Butt Weld Pipe Fittings can be carried out by rapid cooling after heating to around 1100 Degree C.
These Carbon Steel Bend Pipe Fittings have good weldability, where all standard welding processes can be used. Our Carbon Steel Stub End Butt Weld Pipe Fittings are not quite as easily welded as the austenitic grades but low thermal expansion in duplex grades reduces distortion and residual stresses after welding.
Steel pipe elbow is an important parts in plumbing pipeline systems and used to change the fluid directions. It ranges in different types as per body material there are stainless steel elbow, carbon steel elbow, and alloy steel; As per fluid directions there are 45 degree , 90 degree elbow and 180 degree; As per elbow length and radius there are short radius elbow (SR elbow) and long radius elbow (LR elbow); As per connections types there are butt weld elbow, socket weld elbow and threaded steel piping elbow.
