Paper & Pulp Mills
Continuous-run turbines, expansion joints & process filtration for paper mills
Industry Overview
Paper and pulp mills operate steam turbines around the clock, 350+ days per year, making planned maintenance windows extremely tight. The process also involves corrosive bleach, hot water, and high-pressure steam, all demanding filtration and sealing products rated for aggressive media. Keshav Enterprises supplies the complete range of products needed to keep paper mill steam and process systems running.
Key Applications
- Continuous-operation turbine maintenance planning
- Duplex basket strainer supply for process lines
- Expansion joint and bellows supply
- Turbine spares manufacturing to OEM standards
- Machine alignment services
- Vibration monitoring equipment supply
Key Challenges We Solve
Minimal Downtime Windows
A paper machine shutdown costs lakhs per hour. Turbine overhauls must be planned months ahead and executed with zero rework: every component must be right the first time.
Corrosive Process Media
Bleach, chlorinated compounds, and caustic process fluids attack standard materials. Filtration and hose products must use compatible media and seals.
High-Temperature Steam Piping
Paper mill boilers generate high-pressure steam at 250–400°C. Steam piping expansion joints must handle both high temperature and cycle fatigue.
Vibration from Paper Machines
High-speed paper machines generate continuous broadband vibration. Anti-vibration mounts and flexible hose connections are essential to isolate equipment.
Products We Supply for Paper & Pulp Mills
Duplex Basket Strainers
Installed on process water, white water, and cooling water lines. Duplex design allows basket cleaning without stopping flow, critical in continuous-run plants.
- SS316 baskets for corrosive media
- Plug cock bypass valve included
- ANSI 150 to 600 flange ratings available
SS Metallic Bellows Expansion Joints
Absorbs thermal expansion in high-pressure steam piping, pulp process lines, and bleach plant piping without transferring stress to equipment nozzles.
- SS316L bellows for corrosion resistance
- DN15 to DN1200 range
- EJMA design standard, pressure tested
Rubber Expansion Joints (Double-Arch)
Provides flexible connection on pump suction and discharge in water treatment, white water, and effluent systems, isolating pump vibration from piping.
- Natural rubber or EPDM tube options
- PN10/16 flanged ends
- Up to 150°C service temperature
PTFE-Lined Hose Assemblies
Chemical transfer hoses for bleach, caustic, and acid lines in the bleach plant: PTFE lining provides total resistance to aggressive process chemicals.
- PTFE inner core, SS braid reinforcement
- Full vacuum rated
- EN14420-compliant end fittings
Custom Extruded Rubber Profiles & Seals
Custom extruded rubber damping strips fitted under paper machine drives, pumps, and turbine pedestals to isolate and dampen machinery vibration transmitted to the building structure.
- EPDM, Neoprene, Nitrile, or Natural Rubber compound
- Custom cross-section extruded to drawing or sample
- Hardness range 40-80 Shore A per application
Turbine Spares (Siemens, BHEL, Triveni)
OEM-equivalent turbine spares manufactured from certified materials for planned overhaul kits: nozzles, diaphragms, gland rings, and bearing housings.
- Reverse-engineered from OEM drawings
- Material certificates supplied
- CMM dimensional inspection report
