Pipe tee is a kind of pipe fittings used at the branch of the pipeline.For the manufacture of tees with seamless tubes,there are two commonly used processes:hydraulic bulging and hot pressing.
ASME B16.11 threaded equal tees
Hydraulic bulging of tee is a forming process of expanding branch pipe by axial compensation of metal material. Use special hydraulic press machine to inject liquid into the billet with the same diameter of the tee.The billet is extruded synchronously through the two horizontal side cylinders of the hydraulic press.The volume of the billet becomes smaller after extrusion.The liquid pressure in the billet increases with the decreased volume of the billet. When the pressure required for the expansion of the tee branch pipe is reached,the metal material flows along the die cavity and expands the branch pipe under the dual action of liquid pressure in the side cylinder and tube blank.
EN10253-2 P265GH sandblasting equal tees
The hydraulic bulging process of tee can be formed in one time with high production efficiency.Wall thickness of tee head and shoulders are both increased.Because the hydraulic bulging process for seamless tee require large equipment tonnage,the current domestic tee production used mainly for less than the standard wall thickness of DN400.The applicable forming materials are low carbon,low alloy steel,stainless steel,including some non-ferrous metal materials,such as copper,aluminum,titanium,etc.
The lateral tee is threaded reducing tee
Haihao Group supply pipe tee more than 30 years,according to the manufacturing process which can be divided into butt welding tee and forged tee,according to their shape which can be divided into equal tee,reducing tee,lateral tee,straight tee,barred tee.The products materials are carbon steel,stainless steel,alloy steel.The size of tee we provide is 1/2″-96″(DN15-DN2400).We supply the tee according to standard:ASME/ANSI B16.9,MSS-SP-75,DIN 2615,EN 10253-2,JIS B2311,GOST 17378,GOST 17379 etc,.If you want to know more about pipe tees and other piping products,please email us:sales@haihaogroup.com
