Produced in Beijing, China, JHH hydrostatic pressure testing machine is widely adopted within plastic pipe manufacturing labs. It boasts 0.1 % full‑scale measurement precision and can execute tests under pressure levels as high as 10 MPa, equivalent to 100 bar (1450 psi). This test apparatus targets hydrostatic endurance and burst‑resistance evaluation, covering PP‑R, PP‑B, PP‑A, PVC, PE, PE‑X and composite pipe variants. Many global component producers rely on this unit to acquire repeatable test data for new‑product R&D and batch‑release inspection.
