As a mainstream matching accessory for global liquid storage & transportation equipment, it guarantees long-term safe operation of tank equipment with reliable sealing performance.

Model

HT.RKGKSS-500

Nominal Diameter

DN500

Main Material

Integrally forged 304 stainless steel

Rated Working Pressure

0.3Mpa

Operating Temperature Range

-40℃ ~ +180℃

Equipped with multiple quick-release buckles and a small inspection auxiliary cover, the whole set features evenly stressed locking structure and stable sealing. It can be opened & closed rapidly without extra tools, matching standard tank installation dimensions.

The whole cover is integrally forged from 304 stainless steel, which provides strong resistance to acid, alkali, rust and oxidation. It works well with clean water, edible oil, liquid feed, chemical additives and various stored media.

It will not rust, leak or deform after long-term contact with corrosive materials, extending the service life of tank accessories effectively. It helps overseas terminals cut extra costs on frequent part replacement and shutdown maintenance, ideal for harsh working conditions including coastal areas, high humidity environment and chemical material storage.

The DN500 large nominal diameter reserves sufficient operating space. Workers can enter tanks, feed materials, clean tank walls and inspect internal equipment without repeated disassembly. One single operator can finish all operations independently, greatly improving loading, unloading and maintenance efficiency. It is the standard matching size for global liquid tank trucks and vertical storage tanks.

The rated pressure of 0.3Mpa meets the working conditions of atmospheric and low-pressure storage tanks. With a wide applicable temperature range from -40℃ to 180℃, it maintains stable sealing performance in both cold outdoor transportation and high-temperature liquid filling scenarios, eliminating risks of sealing failure and medium leakage caused by temperature fluctuation.

1. Bulk liquid tank trucks: Edible oil transport tanks, chemical liquid tanks, fresh milk storage tanks, purified water delivery tanks
2. Vertical industrial storage tanks: Food raw material tanks, daily chemical buffer tanks, low-temperature storage tanks
3. Sanitation & special transport equipment: Sewage storage tanks, additive tanks, liquid fertilizer storage tanks
