What is Component testing?: Component testing is a method where testing of each component in an application is done separately.
Threaded joints may be permitted in the above ground stations or above ground section of SV stations only if a welded isolation valve is provided before it. The number of threaded joints for station piping shall be to the extent minimum.
The threaded joints, after tightening, may be seal welded. The number of flanged joints for station piping for LPG shall be to the extent minimum. All tapping or opening shall be minimum 20 mm dia.
The specification of Electrical equipments shall be in line with IS: All electrical equipment operating above volts shall have two separate and distinct connections to earth grids. Separate earthing grid shall be provided for instrument and electrical system.
Self conducting structures having metal thickness of more than 4. They shall, however, be connected to the earthing system, at least, at two points at the base. SIS protects against the possibility of a process excursion developing into an incident and limits the excursion potential.
Emergency Shutdown ESD iii. Alarm for hydrocarbon level in the tank iv. Online water analyzer may be installed at the originating pump station to detect any free water in the LPG being pumped.
LPG Pumps shall be provided with a high point vent to safe height minimum 3 meters above the pump in case of no pump shed or 1. Wherever pumps are installed in series, shall have check valve in the header isolating the suction and discharge piping connection.
The last pump in the series shall have check valve on the discharge piping. Additional common check valves shall be installed in the outlet header of the series pump configuration.
The suction and discharge side of the main pumps and booster pumps shall have actuated valves. Low suction pressure of booster and main pump. High discharge pressure at main pump. Low discharge pressure trip on pump against pipe rupture to avoid liquid vaporization. High Casing temperature e.
High bearing temperature f. Tripping of main or booster pump in case of closure of suction or discharge MOVs. Pump shall operate in sequence with defined logic at starting and shut down.
Screwed pipe fittings shall not be used on any part of the fuel system piping or on the day service tank. Seamless tubing with stainless compression fittings are recommended. If the flame arrestor or traps are installed on the exhaust, it shall comply with BS In addition to this, provision shall be made for shut down of the engine on high coolant or lubricating oil temperature.
Electrical motor driven or engine driven air compressors shall be used. Air receivers, air storage bottles and instrument air dryer units shall be provided.
The audio visual indication shall be provided at local panel and the pipeline control room.
Operation of the emergency shutdown system shall also shutdown all Pumps, Prime movers, Control valves and delivery manifold valves except those that are necessary for protection of the equipment. The discharge of TRVs shall be connected to blow down drain connected to a sump tank of appropriate capacity.
These TRVs shall have isolation valves on both sides of safety valve.
All TRV isolation valves upstream and downstream shall be lock open. In this case, isolation valves on downstream of PSVs are not required. A weep hole with nipple at low point shall be provided on the vent pipe in order to drain the rain water which may get accumulated otherwise. Weep hole nipple shall be so oriented that in case of safety valve lifting and consequent fire resulting from LPG coming out from weep hole does not impinge on the structure or equipment.Industry is the production of goods or related services within an economy.
The major source of revenue of a group or company is the indicator of its relevant industry. When a large group has multiple sources of revenue generation, it is considered to be working in different industries.
