EQUIPMENT SPACING The spacing guidelines can vary based on the type of plant (e.g., oil and gas, chemical, power plant), regulatory requirements, and industry standards. However, common factors influencing equipment spacing include: 1. Safety and Hazard Prevention: Flammable Materials: Safe distances between equipment handling flammable or hazardous materials to prevent chain reactions in case of fire or explosions. Firefighting Access: Space for firewater systems and firefighting equipment to maneuver. Ventilation: Adequate spacing for natural ventilation and dispersion of hazardous gases. 2. Maintenance and Operations: Access for Maintenance: Space for personnel to access equipment for repairs, inspections, and routine maintenance. Lifting and Handling: Space for using cranes, forklifts, or other handling equipment during installation or maintenance. 3. Industry Standards and Codes: API 610: Standards for spacing related to pumps. NFPA (National Fire Protection Association): Fire protection standards. ASME (American Society of Mechanical Engineers): Equipment-specific guidelines. Company/Client Standards: Often, companies have internal guidelines based on experience or specific regulatory requirements. 4. Types of Equipment Spacing: Tanks and Vessels: Typically, large storage tanks need to be spaced based on diameter (e.g., 1.5 to 2 times the tank diameter between tanks). Pumps: Pumps need enough clearance around them for maintenance, often ranging from 1 to 2 meters. Heat Exchangers and Compressors: Space for removal of tube bundles or compressor parts during maintenance. Electrical Equipment: Spacing requirements for cooling, safety from fire hazards, and access for electrical panels. 5. Typical Spacing Distances (General Guidelines): Vessels and Towers: At least 5 to 10 meters apart, depending on size and operational hazards. Process Units: 20 to 30 meters between major units for safety and operational efficiency. Fire Hazardous Areas: Spacing of at least 15 to 20 meters from other equipment. Access Roads and Walkways: Generally, 3 to 5 meters wide for ease of access. In summary, proper equipment spacing in industrial plants is essential for safety, efficient operations, and ease of maintenance. By following industry standards and considering factors like fire safety, accessibility, and operational hazards, optimal plant layout can be achieved, ensuring both functionality and long-term reliability.

Just finished the course “Mechanical Systems: Reading HVAC, Plumbing, and Other Drawings and Schematics” by Christopher Randall! Check it out: Christopher Randall explains how to read the drawings and schematics for heating, venting, and air conditioning systems as well as plumbing and piping plans. Learn the difference between process flow diagrams (PFDs) and piping and instrument drawings (P&IDs), how to read and name components of both a simple and a complex P&IDs, and how to read the specific symbols and marks on hydraulic diagrams.

Great article on one of HGG's top shelf mechanical contractors. These guys are no nonsense and put out more spool and structural work than you can fathom. Well done to everyone at Coenen, especially Jim Forbes and Jeff Johnson!!! Thanks for partnering with HGG!

Steam Blowing Acceptance Criteria These criteria will be used to determine when a piping segment has been thoroughly cleaned. The acceptance criteria are: Service Blow These criteria shall apply to vents, drains, auxiliary systems, and any pipe not specifically identified as requiring a Target Blow. Blow the piping until the steam plume/drain is visibly clear of debris. Visually inspect the permanent and temporary piping for abnormal expansion levels. Target Blow These criteria and/or the Steam Turbine Manufacturer’s criteria shall apply to all sections being steam blown that are targeted and require certification. In the case of a conflict between the two criteria, the more stringent of the two will be applied. Blow the pipe until the steam plume is free of visible dirt and debris. The Disturbance Factor during this steam blow period shall equal or exceed 1.05 unless limited by boiler restrictions. Targets may be inserted at any time once the plume has cleared. A minimum of 2 consecutive acceptable targets shall be taken for each steam blow. The final acceptance target must be inserted after a minimum 3hour time period has passed. Successful completion of a target steam blow shall be witnessed and signed off by the Startup Manager. The target bar shall be fabricated of brass polished to a surface texture R max. 6.3 μ. The target bar area subject to inspection shall be 30 mm in width and middle 85% of the internal pipe diameter. The target shall remain in the steam flow path for 10 minutes. A target bar shall be judged acceptable if the following criteria are met. ? No marks > 0.5mm in length or depth. ? No more than two (2) marks < 0.5mm in length and depth on entire target surface and no more than one (1) mark on any 25mm square area on target. ? There are no more than five raised surface marks between 0.3 mm and 0.5 mm per 25 mm square area. ? All marks under 0.3 mm and unraised marks under 0.5 mm shall be ignored. ? The target area corresponds to the middle 85 percent of the pipe inside diameter. ? The above criteria are met in two consecutive steam blows. #Commissioning #Powerplant #CFSPP #CCPP #Boiler #HRSG #Mechanical #Engineer #Expert

#Piping Engineers and #NDT Technicians #How do you #know if a #pipe #failed due to #excess #pressure? Pipe stress engineering covers a wide range of topics. A proper pipe stress analysis requires you to be familiar with various concepts, which are best explained by means of possible failure mechanisms. One of the principle failure mechanisms to be designed for is plastic collapse. This happens when the primary stress occurring in the pipe wall exceeds the yield strength of the material. The internal pressure within the pipe exerts a primary load on the pipe wall. Therefore, it is important to understand the effects of pressure on the behaviour of the induced stress in the pipe. It can be shown that for pressurised piping, the hoop stress is always twice the magnitude of the longitudinal stress. When examining failed piping, it is immediately clear if it failed due to excessive pressure. This can be concluded by looking at the direction of the crack in the material. The crack direction is always perpendicular to the direction of the stress which caused it. This explains why cracks caused by extreme internal pressure always run in the longitudinal direction of the pipe.

Contract advice sought. A good mate of mine makes electric control systems and cabinets. However, he has taken a subcontract job of a main mechanical contractor, to wire up ALL the mechanical plant, to allow it to run Contract value of around ￡150k. "He has said 50% deposit before he starts. and 50% when the job is done" I suspect the Main Mechanical Contractor will never complete the job, so he may never get the final 50%, based upon the fact - the job is NOT done! What are your thoughts on this? #CONTRACT Please click #thecatgetsit ????

** INDUSTRY SAFETY ALERT ** Summary: A worker was being lifted in a quick detach system (QDS) bolter basket attached to a load haul dump (LHD) when the crowd cylinder holding the platform levelled suddenly and unexpectedly extended.?The basket was about 1.8 metres above the ground at the time.? Recommendations to industry:? Mechanical engineering control plans must set out the control measures for the unintended operation of plant. This must include function testing as part of the introducing plant to site process, and pre-use inspections by operators. Mine operators should ensure: - equipment is maintained in accordance with a suitable maintenance strategy considering the original equipment manufacturer’s recommendations and relevant Australian Standards. For elevated work platforms (EWPs) this should include AS 1418.10 and AS 2550.10. - all pieces of hired equipment have a thorough mechanical and electrical inspection to assess the plant’s operation - thorough pre-work inspections are carried out by competent people Source: NSW Resources Regulator - Weekly Incident Summary - Week ending 23 February 2024 #incident?#safety?#underground?#attachments
