New upgrade RGR, more durable with stainless steel coil spring

After 2 years of R&D, testing and domestic field application, Retractable Grounding Reel 's (RGR for short) new stainless steel spring version was fully launched to the international market and won an order for 36 sets of Saudi ARAMCO.

 RGR is widely used for lightning protection and grounding of outside floating roof oil storage tanks. Currently the main measure is to install:

1. Conductive shunt:

2. Soft copper twisted-pair wire of escalator:

However, there are certain hidden safety hazards, so many scenes are equipped with lightning current shunts. The Retractable Grounding Reel is developed for the lightning protection of the external floating roof tank. It can realize the reliable connection of equipotential between the tank wall and the floating disc, make the distance between the floating disc and the tank wall the shortest, provide the lowest impedance channel for the safe discharge of lightning current and bound charges, and reduce the distance between the floating disc and the tank wall The instantaneous over voltage protects the sealed annular area from arcing, which minimizes the possibility of sparks from combustible gases, thereby reducing the possibility of potential safety hazards.

Since our company's Retractable Grounding Reel was launched in 2016, it has exported more than 2,000 sets to the market every year. Taking into account the higher requirements of the oil and gas environment, we strive for excellence, so we make improvements.

What advantages does the new version of the Retractable Grounding Reel have compared with the old version?

1. As we all know, the key to the good operation of the Retractable Grounding Reel lies in the coil spring. The original carbon steel coil spring slowly corrodes the spring after entering the spring cavity under the impact of high temperature and rain, until it breaks, the spring loses its tension, and the device cannot operate. The service life is 2-3 years. 301 stainless steel coil spring is more durable, waterproof and corrosion resistant.

2. The original shell thickness is 1.2mm, now it is increased to 2.0mm, which is more durable.

3. Add anti-air transfer adapter to prevent insufficient pre-tightening force after transport braid.

Being able to win an order from Saudi ARAMCO this time also marks a good start for the cooperation between our company and the international oil company. ALPTEC constantly breaks through itself and improves its equipment to better meet customers' on-site needs.
