why GLEN hook ensure quality

a) The arms shall be hydraulic operated by a hydraulic power pack consisting of stainless steel reservoir, electric motor driven hydraulic pump, valves/fittings and gauges, and hydraulic pipings. All tubings on the arms shall be of stainless steel 316L and prefabricated. Tubings provided for interconnection of hydraulic units shall be of stainless steel 316L and the fitting shall be compression type. b) The hydraulic system shall be sized to provide for full range movement of any component of the loading arm in a maximum of two (2) minutes. The total time required to move each loading arm from its parked position to the tanker's manifold flange shall not exceed five (5) minutes. The hydraulic and electric controls shall be designed to allow manual movement of the loading arms in the event of failure of the hydraulic or electrical systems. Failure of the hydraulic components in one arm shall not render the remaining arms in the bank inoperative.

a) The all swivel joint assemblies shall be made up of ball bearings in at least two replaceable surfaces races with provision for lubrication and maintenance. The swivel joints at the arm riser and apex shall be flanged for maintenance access. Alternatively, swivels shall be of split flange design enabling ease of maintenance. The packing material for all loading arm swivel joints shall be Viton or better material suitable for the intended service and loading products, such as gasoline, pyrolysis gasoline with benzene content, MTBE, toluene and xylenes. The outboard swivel joint shall be self-leveling and with the packing riding on a stainless steel inlay. The stainless steel inlay shall be on both packing faces of the swivel joint. The improved version of swivel joints may be accepted if there are technical and commercial advantages. b) Swivel joints shall be capable of being lubricated without dismantling. A lubricant relief port shall be provided to safeguard against over-press...

This type of filling arm makes liquid phase and gas phase pipeline be concentrated in FB type arm steel structure, adopt hose at the end to connect the boat needed to be filled has a pull off valve. Compared with hanging structure,it is more simple and manual operation, and is suitable for the loading of LNG fuel in a small cargo ship.

This type of filling arm makes liquid phase and gas phase pipeline be concentrated in folding arm of the hose crane, adopt hose at the end to connect the boat needed to be filled and has a pull off valve. Advantages: with a lifting function; can use the hose crane hoisting and unloading drum etc..; electro hydraulic control; be suitable for irregular modified cargo ship to fill LNG fuel.

This type of filling arm is the single arm structure. It is used in group of two sets, one of which transporting LNG and the other transporting NG. At present, the caliber developed is DN100 with Emergency Release System   (PERC). Electro-hydraulic control system is suitable for filling LNG fuel for a large cargo ship, and loading and unloading LNG from the LNG transport ship.

► El ectrical testing ◎ firstly to perform the appearance checking, to ensure there are no any crack, fall off and fault in relation to the anti-explosion cabinet and cable in anti-explosion facilities (include electric motor, cable), and ensure all the connection bolts(pin) and some cable fixed sleeve shall be tightened.   ◎ the resistance between electric part and no electric part in electrical facilities shall not be more than 1M Ω (1000v) ◎ the resistance between the whole equipment and the earth shall not be less than 10 Ω .   ► H ydraulic control system testing The testing pressure shall be 1.5 times of designing pressure, and the testing time will be 5 minutes. ► O peration testing ◎ start-up the electrical and hydraulic control system, to operate the gangway ladder and lifting platform to make them rotating or luffing. ◎  it will take not less then 15 min to performing all the operation activities, the gangway shall meet all the requirements enum...
