Overview
Seals, gaskets, bearings and fasteners are small and relatively inexpensive components, yet their failure is behind a large share of leaks, machine breakdowns and unplanned shutdowns in oil, gas and industrial plants. A leaking flange gasket can release flammable or toxic fluids, a failed bearing can destroy a pump or compressor, and incorrectly tightened bolts can cause joints to loosen or fail. Most of these failures are preventable through correct selection, careful installation, good lubrication and proper maintenance practices carried out by skilled technicians.
This course provides practical knowledge of seals, gaskets, bearings and fasteners used in industrial machinery and static equipment. Participants learn the types and selection of gaskets, flange joint assembly and bolt tightening, and the main types of static and dynamic seals, including O-rings, lip seals, packing and an introduction to mechanical seals. The course covers rolling element and plain bearings, bearing selection, mounting and dismounting, lubrication and failure analysis. It also explains fastener materials, grades and coatings, thread types, torque and tension, locking methods, corrosion of bolts, inspection of components and the root cause analysis of repeated failures.
Objectives
- Select gaskets for different services, pressures and temperatures
- Assemble flanged joints correctly and apply controlled bolt tightening
- Describe static and dynamic seals and their correct installation
- Select, mount, lubricate and dismount rolling element and plain bearings
- Analyse bearing failures and identify their root causes
- Select fasteners by material, grade, coating and thread type
- Inspect components and prevent repeated seal, bearing and bolt failures
Who should attend
Mechanical technicians, fitters, maintenance supervisors, rotating equipment engineers, planners and storekeepers responsible for spare parts.
Training methodology
The course combines explanation of component design and selection with hands-on demonstrations using real gaskets, seals, bearings, bolts and tools where available. Participants select gaskets and fasteners for typical services, calculate bolt torque values, practise bearing identification and mounting methods, and examine failed components to diagnose causes. Photographs of failed bearings, seals and bolts are analysed against failure charts. Case studies of flange leaks and machine failures are discussed in groups. Each day ends with a short quiz and review of key installation practices.
Programme outline
Day1Gaskets and Flanged Joints
- Why flanged joints leak and the role of the gasket, flanges and bolts working together
- Gasket types such as non-metallic, spiral wound, ring type joint and kammprofile gaskets
- Gasket selection based on fluid, pressure, temperature and flange facing type
- Flange face inspection, surface finish requirements and the effect of damage on sealing
- Joint assembly steps, gasket handling and the correct alignment of flanges before tightening
- Gasket storage, identification and the avoidance of reuse and wrong substitutions
- Practical exercise: selecting gaskets for a range of process services and flange types
Day2Static and Dynamic Seals
- O-rings, their materials, groove design and common installation mistakes to avoid
- Lip seals, oil seals and V-rings used to protect bearings and gearboxes
- Compression packing for pumps and valves and the correct installation and adjustment
- Introduction to mechanical seals and the operating conditions they need to work reliably
- Elastomer compatibility with hydrocarbons, chemicals, steam and high operating temperatures in plants
- Seal failure modes such as extrusion, swelling, hardening, wear and installation damage
- Practical exercise: diagnosing seal failures from photographs and operating conditions
Day3Bearings
- Rolling element bearings: ball, cylindrical, tapered and spherical roller bearings compared
- Bearing designations, clearances, fits and how to read bearing numbers correctly
- Mounting and dismounting methods using heaters, presses and hydraulic tools
- Bearing lubrication with grease and oil and the dangers of over-greasing and contamination
- Plain and tilting pad bearings in large machines and their lubrication requirements
- Bearing failure analysis using wear patterns, discolouration and damage marks
- Practical exercise: analysing failed bearings and identifying the root causes of failure
Day4Fasteners and Bolting
- Fastener materials, grades, markings and their suitability for different services
- Thread types, thread engagement and the use of washers and nuts with correct ratings
- Bolt preload, torque and tension and why accurate tightening matters for joint integrity
- Torque tightening, hydraulic tensioning and the use of lubricants and torque charts
- Corrosion of fasteners, coatings and the risks of hydrogen embrittlement in high strength bolts
- Locking methods, vibration loosening and the inspection of bolted connections
- Practical exercise: calculating bolt torque and preparing a tightening sequence for a flange
Day5Inspection, Storage and Failure Prevention
- Inspection of seals, gaskets, bearings and fasteners during maintenance work
- Storage and handling of spare parts to prevent damage, ageing and contamination
- Root cause analysis of repeated leaks, bearing failures and bolt failures
- Standardisation of parts, cataloguing and the control of counterfeit components
- Training, competence assessment and work quality checks for maintenance technicians and fitters
- Group exercise: investigating a repeated flange leak and proposing corrective actions
- Final assessment and discussion of component issues at participants' own plants
