Christmas Tree

♦ Commonly used pressure levels are divided into 21MPa, 35MPa, 70MPa, 105MPa, etc.
♦ The commonly used rated temperature grade is PU (-29℃-82℃).
♦ Material grade: Christmas trees are classified into AA, BB, CC, DD, EE, FF, and HH grades. Among them, grades AA-CC are applicable to environments where the hydrogen sulfide partial pressure is less than 0.3 KPa; grades DD-HH are applicable to acidic environments where the hydrogen sulfide partial pressure is 0.3 KPa or higher. Gas trees are classified into EE, FF, and H grades according to material grades.
♦ Product specification level: Christmas tree specification levels: PSL1, PSL2, PSL3, PSL4; Gas tree specification level: PSL3G.

♦ Product performance levels are divided into PR1 and PR2.
