Waiting for Raw Water (Actiflo) Pic. 1 Re-Start Again

It's been too long for Piping and Fabrication to wait Raw Water Line drawing 1 to continue again, there is still much work to do on Raw Water Line, including huge pipe size which is DN800 or 32 inch that we have to fabricate and erection.

Below here is an isometric drawing for Raw Water Line and almost 70% from that line is not finish yet, and we hope we can have enough man power to finish those line.

Isometric for Raw Water Line drawing No. 1

Can we finish those line in time? we hope we can do it, it's up to many circumstances, technical or non technical situation.

This is Piping & Fabrication write for you all just for information and share. Thanks for visiting!

THE PROCESS OF JOINT INTEGRITY

THE PROCESS OF JOINT INTEGRITY
This is what we want to see and this is also what Piping and Fabrication mean to keep ON AIR until now, to provide us with valuable information like this, enjoy it.

To assist in managing a process, ask yourself the following questions: why, what, who, and how? Why do we need a Flange Joint Integrity program? This was addressed in the previous section, ‘‘Cost of a Leak.’’ The stakes are enormous. A Flange Joint Integrity program will help improve plant safety and reliability while reducing its environmental impact. What do we need to control? The operating environment, the components, and assembly all need to be controlled. Who do we need to control? The designers, field operatives, and supervisors. How do we control? Train personnel to required competency. Design components using latest engineering standards. Develop best practices for assembly and maintenance. Implement a quality assurance program that provides traceability and ensures compliance to specifications. There are over 120 variables that affect flange joint integrity. These can be controlled through the following categories:
● Environment (internal and external)
● Components
● Assembly

The internal environment outlines the design and operating conditions of temperature, pressure, and fluid. With the external environment, consideration is given to location of the flange, whether it is operating in air or sub-sea, and externally applied piping loads. An understanding of the environment is crucial to the design and selection of the appropriate components with the correct assembly methods. The components include the most appropriately designed and selected flange, gasket, and bolting, commensurate with the risk dictated by the environment. Assembly includes checking the condition of the components and proceeding according to established procedures. Proper assembly requires that
● Flange faces meet the standards
● Gasket-seating stress is achieved
● Bolts, nuts, and gaskets are free of defects
● Appropriate lubrication is used

Execution requires trained, competent people using the correct tools and following procedures.

Thanks for Visiting Piping and Fabrication and see you always.

Fabrication Practices which is Cutting and Bevelling

Fabrication Practices

Now Piping and Fabrication will start again to write about all what we need in Piping System, and now we entering with Fabrication Practices which is Cutting and Beveling. 

The methods of cutting plate or pipe to length can be classed as mechanical or thermal. Mechanical methods involve the use of saws, abrasive discs, lathes, and pipecutting machines or tools. Thermal methods are oxyfuel gas cutting or electric arc cutting. Oxyfuel gas cutting is a process wherein severing of the metal is effected by the chemical reaction of the base metal with oxygen at an elevated temperature. In the cutting torch, a fuel such as acetylene, propane, or natural gas is used to preheat the base metal to cutting temperature. A high-velocity stream of oxygen is then directed at the heated area resulting in an exothermic reaction and severing of the material. Oxyfuel gas cutting is widely used for cutting carbon steels and low alloys. It does, however, lose its effectiveness with increasing alloy content. For higher alloy materials, some form of arc cutting is required. Plasma arc cutting is the process most frequently employed. It involves an extremely high temperature (30,000 to 50,000°K), a constricted arc, and a high-velocity gas. The torch generates an arc which is forced to pass through a small-diameter orifice and concentrate its energy on a small area to melt the metal. At the same time a gas such as argon, hydrogen, or a nitrogen-hydrogen mixture is also introduced at the orifice where it expands and is accelerated through the orifice. The melted metal is removed by the jetlike action of the gas stream.

Because oxyfuel gas and arc cutting involve the application of heat, preheating may be advisable in some cases. Weld end bevels can also be prepared by the mechanical or thermal methods just described. Both mechanical and thermal methods are used to apply the V bevel, which is used in the vast majority of piping applications. For compound and U bevels or those which may involve a counterboring requirement, horizontal boring mills are most appropriate. Various factors to be considered in selecting a weld end bevel are discussed in the section, ‘‘Welding Joint Design.’’

Finished Hydro Test for Sand Filter or Multigrade Line

Finally we can completed the Sand Filter Line with finished Hydro Test 10.7 Bar. Piping and Fabrication just want to inform all of you that Sand Filter Line is Done, just few more Joint to the Suction Pump and we plan that will finish fabrication and install in this week.

 10.7 Bar Pressure on Hydro Test Display on Pressure Gauge at 14.45 WIB

Pressure still remain 10.7 Bar on the one hour Holding Time

And now we can focus to the Additional Work for WTP Project such as Fill Softener Tank with Resin, Modification Frontal Piping on Softener Tank, etc.

We never boring to Thanks to the teams and anyone who get involves in this WTP Project. Congratulations Teams, We still have Raw Water Drawing 1 waiting to get our touch. 

Evaluation for Water Treatment Project

In the end of Water Treatment Project for all the lines such as Filter Water, Soft Water, Raw Water, Sand Filter, Dynasand and etc, including all the Equipment or Tank, Multigrade Tank, Softener Tank and Demin Water Tank, there is so many thing we can learn from that project.

It's really hard to control people or can we call Man Power, because we have a big hope to them, when we hire them, they will do as professional worker, but the fact is we have to make them work, teach them how to work, and told them how to work and that's really such a big problem for me and my team. But, we have to take that responsibility, because we can't hire another worker, they all the same, mostly they can't work especially helper.

Luckily that we had very competent and good leader, so they can arrange all that worker, even we know that's really hard but we have to use them. Not mention the users want to do this, want to do that, like they never know the problem on the field, everything can goes wrong if we push them too much.

Piping and Fabrication only hope everyone will understand that we already work as maximum as we can, as hard as we can and we can do nothing more than it, this is the best what we can do for now. We hope, we really hope.

Thanks for everyone who supporting us to finish this WTP Project, especially my teams, once again thank you very much.

Soft Water Line is Done

Same like Filter Water, Raw Water and Dynasand, Soft Water is Done and we already finish Hydro Test for Soft Water too. Piping and Fabrication will inform this to all of you just to inform to anyone who involve with this process.

But, still there is still plenty of work that we must done in short of time, next is Sand Filter and Softener Tank. Under my supervise and Mr. Fandi, we will try to finish Softener Tank this week, because next week all line has to running to supply water for Fiber Plant Line 5.

Once again, thank you to everyone who involve with this project and of course my team, congratulation Teams! I don't know how to thanks to all of you, because I've seen myself that Soft Water Line drawing is really different with actual site condition, there is too many modification we have to do, such as cut and re-weld, different size, different elevation, etc.

Filter Water Line is Completed with Successful Hydrotest

I know it's been a little bit late when I inform this, because probably it's almost few weeks ago that Filter Water Line is completed. We are glad that we can finish the Filter Water on time, of course with much help from my teams and the others. Without them, we are nothing. Filter Water Line completed with Hydro Test process with almost 11 Bar Pressure and we found no leakage.

Here it is the pictures of Hydro Test, we start from 16.45 to fill the water in, and at 17.50 the pressure start stabilize and we start holding time about 1 hour and finish about 19.00 WIB. This is Piping and Fabrication Reporting.

Pressure at 11 Bar for Filter Water Hydro Test

Starting Holding Time at 17.50

Filter Water is Completed

Once more we are thanks to someone always helping us which is Mr. Pandi, because he always lead us and warn us if there is some problem with our job, and of course to my teams, Congratulations Teams!
