Mechanical

Above-ground piping fabrication involves a structured workflow of design, material preparation, welding, inspection, and installation, all governed by ASME B31.3 and OISD safety standards. It ensures leak-free, durable systems for industrial plants, firewater networks, and LPG facilities.

ASME Section II – Materials is the backbone of the Boiler and Pressure Vessel Code (BPVC), providing the official library of approved material specifications, properties, and allowable stresses used across all ASME construction codes. It is divided into four parts: Part A (Ferrous materials), Part B (Nonferrous materials), Part C (Welding consumables), and Part D (Material properties and stress values).

ASME Section IX – Welding, Brazing, and Fusing Qualifications is the part of the Boiler and Pressure Vessel Code (BPVC) that governs how welding and brazing procedures, as well as the performance of welders and welding operators, are qualified. It ensures that joints made in pressure equipment are safe, consistent, and meet code requirements.

ASME Section V – Non-destructive Examination (NDE/NDT) is the part of the Boiler and Pressure Vessel Code (BPVC) that establishes the rules, procedures, and acceptance criteria for non-destructive testing methods used in pressure equipment fabrication, inspection, and certification. It ensures that welds, materials, and components are free from unacceptable defects without destroying the part.

ASME Section VIII Division 1 is the most widely used part of the Boiler and Pressure Vessel Code (BPVC). It governs the design, fabrication, inspection, and certification of pressure vessels and heat exchangers operating at pressures above 15 psig. Division 1 provides rules for vessels built with relatively straightforward design methods, making it the industry standard for LPG storage tanks, heat exchangers, and process vessels.

ASME Section VIII Division 1 – Pressure Vessel Fabrication lays out the rules for how vessels are physically built after design approval. It ensures that every stage of fabrication—cutting, forming, welding, inspection, and testing—meets strict safety and quality standards.

Casting & Forgings Inspection is a critical quality assurance step in pressure vessel, piping, and machinery fabrication. It ensures that raw components meet mechanical, dimensional, and metallurgical requirements before being welded or assembled.

Heat Exchanger Fabrication Inspection is a structured process ensuring that shell-and-tube, plate, or finned exchangers meet ASME Section VIII Div. 1 requirements for safety, performance, and durability. It combines dimensional checks, material verification, welding inspection, and pressure testing.

Heat treatment is a controlled process used to alter the physical and mechanical properties of metals—improving strength, hardness, ductility, or toughness. It is essential in fabrication of pressure vessels, piping, and heat exchangers to relieve stresses and achieve desired material performance.

Hot Dip Galvanizing (HDG) is a protective coating process where steel or iron components are immersed in molten zinc to form a metallurgically bonded layer that resists corrosion. It’s widely used for piping, structural steel, tanks, and outdoor equipment.

LPG Cylinder Design and Manufacturing is governed by stringent safety codes (IS 3196, IS 5841, ISO 4706, and ASME Section VIII Div. 1 principles). The process ensures cylinders can safely store and transport LPG under pressure, with robust design, fabrication, and inspection.

Inspection NDE/NDT Level II procedures are structured inspection practices carried out by certified personnel to ensure welds, castings, forgings, and fabricated components meet code requirements. A Level II inspector is qualified to set up equipment, conduct tests, interpret results, and supervise Level I technicians.

Pipeline laying and testing is a critical process in oil, gas, water, and LPG distribution systems. It involves careful planning, execution, and inspection to ensure safety, reliability, and compliance with ASME B31.4/B31.8 and IS codes.

Storage Tank Fabrication involves a highly controlled process to ensure tanks used for petroleum, LPG, water, or chemicals meet ASME Section VIII Div. 1, API 650/620, and IS 803 standards. It covers design, material preparation, welding, inspection, and testing before commissioning.

ASME Section II- Materials ASME Section II – Materials is the backbone of the Boiler and Pressure Vessel Code (BPVC), providing the official library of approved material specifications, properties, and allowable stresses used across all ASME construction codes. It is divided into four parts: Part A (Ferrous materials), Part B (Nonferrous materials), Part C (Welding consumables), and Part D (Material properties and stress values).
