Critical Process Piping Fabricated to ASME B31.3 Standards
In modern industrial complexes, piping is the circulatory system. A single defect in a high-pressure hydraulic line or a failed fire hydrant weld can trigger catastrophic production downtime or life-safety violations.
Krishna Engineering Works delivers full-spectrum fluid handling solutions: from heavy seamless carbon steel and stainless steel spools, to corrosion-resistant HDPE butt-fused piping and chemical pickling circuits. Our qualified pipe fitters and TIG/MIG welders assemble lines that withstand extreme pressure cycles, thermal expansions, and corrosive media.
For Keihin Fie India, we designed and routed seamless hydraulic pipelines feeding high-tonnage aluminum die-casting machines. For India Japan Lighting (IJL), we fabricated a monolithic 150KL Industrial Fire Water Tank & Hydrant Network, delivering 100% hydrostatic compliance on first pressurized charge.
Industrial Piping & Fluid Handling Disciplines
Seamless Hydraulic Lines
Precision bent seamless heavy carbon steel piping (ASTM A106 Gr. B) for automated die-casting machines, hydraulic presses, and high-pressure fluid power loops.
Fire Fighting & Hydrant Networks
Complete TAC-compliant fire hydrant lines, sprinkler headers, deluge valves, pump houses, and high-capacity fire water reservoir tanks (150KL+).
HDPE Process & Effluent Piping
High-Density Polyethylene (HDPE PE100) butt-fusion welded lines for chemical transfer, industrial effluent handling, and cooling water circuits.
Chemical Pickling & Passivation
Multi-stage chemical cleaning, acid degreasing, rust scale pickling, and citric/nitric passivation conforming to ASTM A380 to guarantee internal cleanliness for sensitive hydraulic media.
Specialized Field Services
High-hazard technical procedures executed under strict permit-to-work (PTW) protocols.
Spark-Free Cold Cutting
Pneumatically and hydraulically driven cold-pipe cutters for cutting and beveling live or hazardous chemical lines without open flames or sparks.
Flange Bolt Tensioning & Torqueing
Hydraulic bolt tensioners calibrated to ensure zero flange leakage on high-pressure steam, thermal oil, and chemical transfer lines.
Instrument Calibration
Certified testing and calibration of pressure gauges, differential transmitters, temperature sensors, and safety relief valves (SRV).
Thermal Insulation & Cladding
Mineral wool, rockwool, and ceramic fiber pipe insulation clad in 24G aluminum or stainless steel jacketing for energy efficiency.
