Posisi Piping Material atau Piping Engineer merupakan jabatan penuh tantangan dan memberikan harapan yang sangat bisa dibanggakan…

 

Please read it and meet the requirement and you have a chance to be expert with good remuneration packaged.

 

 

 WHAT IS A PIPING MATERIAL ENGINEER

 

The piping engineer, who is responsible for the quality of piping material, fabrication, testing, and inspection in a project and the major activities such engineers are expected to perform. This individual can be employed by either the EPC (engineering, procurement, and construction) contractor or the operator/end user.

 

Job Title

 

The piping engineer, the individual responsible for creating the project piping classes and the numerous piping specifications necessary to fabricate, test, insulate, and paint the piping systems, is titled either the piping material engineer or the piping spec(ification) writer.

 

Job Scope

 

Whatever the title, the piping material engineer (PME) is a very important person within the Piping Design Group and should be dedicated to a project from the bid stage until the design phase has been completed. He or she should also be available during construction and through to mechanical completion.

 

The lead piping material engineer, the individual responsible for all piping engineering functions, usually reports directly to the project lead piping engineer, and depending on the size of the project, the lead piping material engineer may be assisted by a number of suitably qualified piping material engineers especially during the peak period of the project. This peak period is early in the job, while the piping classes are being developed and the first bulk inquiry requisitions are sent out to vendors.

 

The Piping Material Engineer’s Responsibilities

 

The piping material engineer’s responsibilities vary from company to company. Here is a list of typical functions that he or she is expected to perform:

 

a.       Develop the project piping classes for all process and utility services.

b.       Write specifications for fabrication, shop and field testing, insulation, and painting.

c.       Create and maintain all data sheets for process and utility valves.

d.       Create a list of piping specials, such as hoses and hose couplings, steam traps, interlocks.

e.       Create and maintain data sheets for these piping special (SP) items.

f.        Assemble a piping material requisition with all additional documents.

g.       Review offers from vendors and create a technical bid evaluation.

h.       Make a technical recommendation.

i.        After placement of a purchase order, review and approve documentation from vendors related to piping components.

j.        When required, visit the vendor’s premises to attend kickoff meetings, the testing of piping components, or clarification meetings.

 

 

 Qualities of an Engineer

Not only is it essential that a piping material engineer be experienced in several piping sectors, such as design, construction, and stress, he or she must also be a good communicator, to guarantee that everyone in the piping group is aware of the materials of construction that can be used for piping systems. The PME must also have a basic understanding of other disciplines having interface with the piping, such as mechanical, process, instrumentation, and structural engineering. He or she should also be aware of the corrosion characteristics of piping material and welding processes necessary for the fabrication of piping systems. Both corrosion and welding engineering are specialist subjects, and if the PME has any doubts, he or she must turn to a specialist engineer for advice.

 

 

Experience

 

There is no substitute for experience, and the piping material engineer should have strengths in several sectors and be confident with a number of others disciplines, to enable the individual to arrive at a suitable conclusion when selecting material for piping systems. Strong areas should include piping design layout and process requirements. Familiar areas should include the following:

 

.  Corrosion.

. Welding.

. Piping stress.

. Static equipment.

. Rotating equipment.

. Instruments.

 

 

PIPING MATERIAL ENGINEER’S ACTIVITIES

 

Outlined here are the principal activities of a piping material engineer. These are listed in chronological order as they would arise as a project develops from preliminary to detailed design. The Piping Material Engineer

 

Development of the Project Piping Classes

 

All process plants have of two types of principal piping systems:  process (primary and secondary) piping systems and utility piping systems. Process piping systems are the arteries of a process plant. They receive the feedstock, carry the product through the various items of process equipment for treatment, and finally deliver the refined fluid to the battery limits for transportation to the next facility for further

refinement. Process piping systems can be further divided into primary process, which is the main process flow, and secondary process, which applies to the various recycling systems. Utility piping systems are no less important. They are there to support the primary process, falling into three groups:

 

·         Support—instrument air, cooling water, steam. .

·         Maintenance—plant air, nitrogen. .

·         Protection—foam and firewater.

 

There are other utility services such as drinking water. Piping Classes. Each piping system is allocated a piping class, which lists all the components required to construct the piping. A piping class includes the following:

 

. Process design conditions.

. Corrosion allowance.

. List of piping components.

. Branch table.

. Special assemblies.

. Support notes.

  1. dear MR.novembri

    saya sangat tertarik dengan tulisan 2 bapak,
    pak bagi ilmu tentang piping stresss analysis.

    thanks
    best regard
    martion

    • Pak Syofyan..bicara ttg piping stress analysis , mulai dari mana ya…? Secara general piping perlu dilihat dia stress atau nggak? Sama dengn manusia yang suka stress. Kalau mereka mengalami banyak beban hidup dan nggak ada cara untuk mengurangi beban hidupna maka manusia akan jadi stress…. kalau masih sedikit bisa langsung di obat, kalau sudah berat mungkin bisa macam macam, bunuh diri, gila, dll.
      Pipingpun demikian, dia mengalami stress karena beban yang dialaminya. Untuk mengetahui pipa stress atau tidak maka perlu dianalisa…bagaimana cara menganalisanya….? Disamping dengan caramanual dengan calculation sifat material dan beban yang akan diterimanya maka bisa ketahuan dia fail atas pass. Tapi cara ini khan untuk yang sederhana…namun kalau sudah masuk ke element yang komplec maka bisa dengan menggunakan software. Unutk pipa bisa dengan mengguakan Caesar II.
      Bagaimana cara menjalankan software ini dan perhitungan perhitungan dan data yang di input….kita perlu mentor dan sebaiknya bapak ikut traiing Caesar II saja. Karena banyak yang harus di pelajari.

      Saat ini demand untuk pipe stress sangat tinggi khususnya di perusahaan eng company. kalau melirik ke S pore tiap hari bisa 20 posisi yang dicari di internet…

      Untuk informasi trainig oil dan gas bisa ikut di offsore technology institute alamat web http://www.batamtraining.com

      salam sukses

  2. Pak Nov isa ga ngadain workshop di itb mengenai pelatihan software caesar II ?

  3. found very useful.thank you

  4. ada ga training pipa d jkta
    kira kira biayany brp?
    Thanks

  5. Artikel yang bagus pak Novembri..
    Kira-kira kalau yang background experiencenya QC inspector untuk penerimaan material fi fabricator untuk masuk bidang ini skill apa yang perlu diperkuat pak?

  6. Salam
    Mohon masukannya.
    Saya lulusan S1 Teknik mesin sekarang bekerja di pembangkit listrik.
    Saya tertarik melanjutkan S2 ke Universitas Indonesia Program studi Teknik Metalurgi dan material. namun saya bingung memilih antara kosentrasi material atau korosi. dilihat dari prospek pekerjaan mana yang lebih terpakai di industri, terutama di migas.
    terima kasih
