Pipe testing machines are designed to simulate the large variety of pipe conditions that prevail in the industry and other manufacturing environments. The machine helps in detecting problems before they lead to large scale structural failure. In case of internal piping the machine provides information on pipe strain testing, visual inspection of pipe joints, diameter testing, freezing/ thaw testing and hydrostatic testing. These tests can easily be conducted without human supervision and within a short period of time. The machine is ideal for non-continuous inspections. It provides fast and reliable data and is ideal for pretest completion and maintenance.
The Pipe Testing Machine is built with two independent tests and a bench mounted diagnostic instrument for detecting problems in a wide range of standard and flexible pipe materials. The machine is equipped with the latest instruments and control systems and has been designed to meet the most stringent international standards. The machine has a user-friendly control panel and with the optional accessories it can perform a number of advanced tests. The bench mounted diagnostic instrument facilitates the user to carry out pretest, posttest, maintenance inspection and repair services.
The machine uses high-precision sensors for hydrostatic testing and offers fast, reliable and economically-sound results. The hydrostatic testing machine can also test pipes of the drain and sewer lines, concrete pipes and box culverts (STD-STD-L) when employed with optional accessories. The bench-mounted diagnostic instrument facilitates the user to do precision measuring and to prepare comprehensive reports. The bench-mounted pressure transducer is available in a number of different types including digital, polygonal, line, and flexure-flexure types, and it can be used for many different pipe applications including: hydrostatic testing, pre-tension testing, and pipe sizing and wall panel sizing.
The pipe testing machine is also useful for detecting the presence of soil in the joints. It helps in reducing the downtime required for this important maintenance process. During this process, the operator inserts a PVC edge clamping device and clamps the plastic pipe to the appropriate joint or series of joints. The clamping pressure increases as the pipe ages, and the metal or plastic pipe is then tested for shrinkage, internal pressure, stress cracking, as well as the formation of mild steel rust.
The hydrostatic test pressure that is applied on the plastic pipe depends on the legal analysis issued by the USPMS. The USPMS assigns a production code number to a product, and if the plastic pipe meets the guidelines set forth by the USPMS it will be assigned a legally-defined production code number. For a product to be valid for manufacturing in the US, the PVC pipe must pass all three of the following codes:
This machine is a useful tool for inspectors and engineers who perform hydrostatic testing of piping systems because of its ease of use and speed. The push plate and movable cylinder make it easy to perform the precise tests needed to determine the stresses and strain levels within a piping system. The plastic pipe is inserted into the push plate and connected to the cylinder to determine the amount of material that will be pulled away from the pipe wall. Then, the cylinder is moved up and down to increase or decrease the distance between the inside surface of the pipe to the outside surface of the cylinder and vice versa. The PVC pipe is then tested under different pressures to determine the amount of strain it can withstand before breaking.
