Hydro Testing Machine

It adopts two lifted rollers to hold the tested steel pipe, 
using the thrust of master cylinder to press the pipe between the thrust plate and the pressure plate, 
so that the pipe two ends can be sealed(end face seal or radial seal).

1. Introduction

The equipment is used for kinds of steel pipe pressure-bearing and testing non-standard equipment.

It adopts two lifted rollers to hold the tested steel pipe, using the thrust of master cylinder to press the pipe between the thrust plate and the pressure plate, so that the pipe two ends can be sealed(end face seal or radial seal).

Based on high-volume low-pressure pump to complete the water injection, and then use high-pressure pump to complete high pressure test.
