Manufacturing Capabilities


Design Codes and Standards

We have one of the largest resource base for process design, engineering and execution. Also for mechanical and piping design we are operating with well-set practices and infrastructure.
As a participant in the global chemical industry, it is imperative that we follow the stringent codes and standards that meet the designing and safety norms of the industry.
We follow the below mentioned codes and standards -

  • ASME Section VIII – Div I & Div II
  • Pressure Equipment Directive (PED)
  • TEMA
  • BS 5500
  • API 650 / API 620
  • AD-Merkblatter
  • IS 2825
  • PD 5500


Understanding of metallurgy and the fabrication skillset are the two most important factors determining the quality and aesthetics of the equipment. Over the years, Praj has developed the capability to work with a variety of metals. We have climbed the complexity level on every parameter – material of construction, thickness and also, the scope of work.

  • Carbon steel – all grades, including NACE, SSC, HIC
  • Alloy steel – various grades & combination of Cr, Ni, Mo, Ti etc
  • Non ferrous – Cu, Ni, Brass, Co, Ti and their alloys
  • Stainless steel – Austenitic, Ferritic, Duplex and Super Duplex
  • Clad steel – CS and LAS with Cu-Ni, Monel, Inconel, SS, Ti, Ni cladding

Quality Systems


  • ISO 9001 : 2015
  • ISO 14001 : 2004

Health, Safety and Environment


At Praj, we believe that safety is a way of life and is not optional. At all our locations, including various project sites, we follow stringent practices for safety and well-being of everyone. We have a thoughtfully documented HSE policy and have adopted ISO 9001:2008, ISO 14000 and OHSAS certification.

During the FY 2016-17, Praj Sanaswadi factory was bestowed with the prestigious National Safety Council Award 2016. This annual award is institutionalized by the National Safety Council (NSC) to acknowledge efforts in the area of health, safety & environment. NSC is a premier, apex body with the goal of creating a preventive and scientific approach to HSE issues.
