Manufacture process of high pressure tee

Pipe tee is a type of pipe fitting which is T-shaped having two outlets,at 90° to the connection to the main line.It is a short piece of pipe with a lateral outlet.Pipe tee is used to connect pipelines with a pipe at a right angle with the line.The manufacture process of high pressure tee as follows:

The raw materials prepared by high-pressure tee should be baked at high temperature,and the high-quality white ash should be used in the refining furnace,but the white ash mixed with impurities should not be used.The content of pig iron in the ingredients should be higher than 30%.

During the exercise,we should try our best to increase the full-melt carbon to ensure that impurities and bubbles are discharged.The tapping temperature of tee steel is higher than 1650 degrees Celsius.After the slag is converted, it needs to be deoxidized.After chromization,the slag is whitened by deoxidation of aluminium particles.In this process,mix with nitrogen.Sampling and analysis should be carried out when the composition adjustment is appropriate until the pouring conforms to the specifications.

In the future,ingot demoulding will be sent to casting within one and a half hours.After 20-60 hours in the pit,the high-pressure tee should be heated in the high-temperature furnace when the temperature is 650-750 degrees Celsius.Then forging and annealing are carried out.In order to prevent deformation,there is a certain demand for tempering temperature to ensure that tempering temperature can not be too high and tempering uniformity.Then sampling and dissecting.
