Piping or pipes are objects that are used for various types of fluid. More in detail, piping or pipe is an integrated system with that of one with laainya enabled to transport the fluid from one location to the other location. In the world of engineering, plumbing is a discipline of its own in order to obtain good design, proper material and considerable flexibility.
In the industrial world, the piping system is subdivided into three disciplines. The three are:
1. Piping Design
It is the discipline that designs equipment piping system from one equipment to another or from one location to another. In addition, there are adult as the design specification has been using PDMS or PDS software so there is no design errors made several designers.
2. Piping Materials
This discipline is more to the selection of the pipe material, other specifications such as welding, specification insulation, painting specification, fabrication specifications, and others.
3. Piping strees and Flexibility
This section will analyze the design of certain pipe sections desin (critical piping). The discipline required for some types of software, among others Autopipe and Caesar.
Purging and pigging usually used at the time of discharge pipes (for replacement chargo or there will be modififikasi pipe). Purging and pigging is to ensure no entrapment of gas or flammable liquids in the pipes. The purging process is the process of blowing the rest of the gas / liquid - chemical / mogas / olie- in the pipe using N2 or Air Compressor gas or steam depending on the MSDS (material safety data sheet) it, for example purging flammable chemical use N2 but if Olie Air Compressor can be used, or if a gas such as VCM use Steam after purging / blowing usually do 'Shocking' by way meng'keep 'pressure to limit certain pressure and then thrown away suddenly so that the rest of the gas / liquid can then be carried on last-process is pigging by entering the type of rubber bullets or polyurethane size according pipe tool launcher called PIG Launcher and the recipient is called PIG receiver after a few times in pigging and seen no gas / liquid then carried gas test, and if the results of gas test new good may be done cutting and welding sometimes we blew Air Compressor or steam pipe leading to the farthest to ensure no residual gas trap that led to the pipe being in welding / cuttin.

Purging and Leak Test Procedure
Leak Test
To ensure that the pipeline has been completed dialakukan welding / welding necessary / required to do testing of the quality of welding is one of them to perform a leak test on the piping (leak test), daiantaranya dialalui stages are as follows:
Checking line pipe leak test to be performed, that is by inspecting the pipe if there weldingan left, the component is not installed or not in welding and line pipes that have not been installed.
Doing bolts, nuts if it is appropriate firmness specified standards, as well as check the gasket attached.
Making a connection by means of a jumper on the necessary plumbing.
Closing the pipe by installing a blind flange to the line pipe line that goes into the engine, control valve, appliance instrument, tanks and other components.
Installing a point for the placement of the pressure gauge (usually using two pressure gauges are placed above and below), and to install pipes to inject air or water.
