Growing numbers of overseas pipe fabricators select JHH hydrostatic pressure testing machine, which originates from Beijing, China, to complete pipeline performance assessment. This test unit features 0.1 % full‑scale measurement precision and supports test pressure up to 10 MPa (100 bar,1450 psi). It is capable of testing plastic pipes and composite pipe products such as PP‑R, PP‑B, PP‑A, PVC, PE, PE‑X, generating valid data for hydrostatic endurance and burst‑resistance performance judgement during product certification and production batch inspection.
