Structures

In refinery operations, structures refer to the engineered steel frameworks and support systems that provide physical stability, access, and protection for process equipment, piping, and personnel. These include pipe racks, platforms, stairways, walkways, equipment foundations, and shelters, all designed to withstand operational loads, environmental conditions, and safety requirements.

Description

Structural systems in refineries are essential for safe and efficient plant functioning. They support critical equipment such as columns, reactors, heat exchangers, and tanks, while also facilitating maintenance access and operational mobility. These structures are typically fabricated from carbon steel or galvanized steel and are designed in accordance with IS, ASTM, and API standards to meet load-bearing, wind, and seismic criteria.

Inspection & Assessment

  • Visual and dimensional inspection of steel structures, platforms, and supports
  • Non-destructive testing (NDT): ultrasonic, magnetic particle, and dye penetrant for weld joints and load-bearing members

Maintenance & Repair

  • Welding repairs on beams, columns, braces, and connections
  • Replacement of corroded or damaged members
  • Bolt tightening and fastener replacement
  • Protective coating and painting for corrosion prevention

Fabrication & Erection

  • Fabrication of structural steel components: pipe racks, platforms, ladders, handrails, and walkways
  • On-site erection and alignment of steel structures
  • Installation of cable trays and pipe supports

SnC Infratech offers a full range of structural services, beginning with inspection and assessment of existing frameworks using visual checks and non-destructive testing methods to identify corrosion, deformation, or weld defects. Our maintenance services include welding repairs, replacement of damaged beams, braces, and supports, as well as bolt tightening and protective coating applications to prevent corrosion. We also specialize in the fabrication and erection of new structures, including pipe racks, platforms, ladders, handrails, and cable trays, ensuring precise alignment and secure anchoring.

Cleaning & Surface Preparation

  • Surface cleaning using sandblasting or hydro jetting
  • Rust removal and surface treatment
  • Application of fireproofing or anti-corrosive coatings

Documentation & Compliance

  • Fabrication records
  • Inspection and repair reports
  • Compliance with IS, ASTM, and API standards
For modification and upgrade projects, we reinforce existing structures to accommodate new equipment, reroute piping systems, or improve load distribution. Our team is equipped to retrofit access systems such as staircases and catwalks, and to install fireproofing or anti-corrosive coatings for enhanced durability. All work is executed under strict safety protocols and documented with as-built drawings, inspection reports, and compliance records. With a focus on precision, safety, and turnaround efficiency, SnC Infratech ensures that refinery structures remain robust, compliant, and ready to support continuous operations.

At SnC Infratech, we deliver comprehensive structural services that support the safe and efficient operation of refinery facilities. Our expertise covers the inspection, fabrication, erection, maintenance, and modification of steel structures such as pipe racks, platforms, stairways, walkways, equipment foundations, and shelters. We begin with detailed assessments using visual inspection and non-destructive testing techniques to evaluate corrosion, weld integrity, and structural alignment. Based on these findings, we perform welding repairs, replace damaged beams and supports, and apply protective coatings to extend service life. Our fabrication and erection capabilities include the production and installation of custom steel components, ensuring precise alignment, secure anchoring, and compliance with IS, ASTM, and API standards. For upgrade and expansion projects, we reinforce existing structures to accommodate new loads, reroute piping systems, and retrofit access systems such as catwalks and ladders. We also install fireproofing and anti-corrosive coatings to enhance durability in harsh operating environments. All work is executed under strict safety protocols and documented with as-built drawings, inspection reports, and compliance records. With a focus on precision, safety, and turnaround efficiency, SnC Infratech ensures that refinery structures remain robust, compliant, and ready to support continuous operations.
