The product is made of high strength aloy steel and heat treatment,so it has the advantages of long service and can ensure the rated working pressure, the elbow is equipped with steel ball in quenched track ,therefore it can rotate flexibly.The ends of elbow not ony can use LP box connection but also can use union connection ;It is suitable for installment in different kinds of pipelines .

The structure of long radius can minimize the corrosion of medium flow ; the first layer sealing is synthetic rubber with the BOP ring of binder metal ,if the sealing appears exudation , the Grease check rng of pressure reduction automatic will prevent the pressure from accumulating in the raceway.Steamlined bore minimizes flow resistance,the diameter is designed as gradual circle which will turbulent flow and pressure drop ,Semi major anxis movable elbow can gain better liquidity
