Skid-mounted equipment (the literal translation of skid-mounted means being installed on the sliding bottom plate, and the meaning of “skid” is utilized); skid-mountingmeans to fix a group of equipment on a chassis made of angle iron or joist steel, and the equipment can be moved and put into space through a crow bar and the modern hoisting equipment; skid-mounting is a form for integral combination of an equipment framework and the equipment thereof. A loading skid is an overall integrated part of an integrating loading controller, flowmeter valves, pipelines, accessory equipment, crane pipes, middle connectors and cables and cable traies on an overall steel-constructed platform with a process connector, a control power supply and a communication interface reserved only.
1. Flexible and small in size
The skid-mounted equipment is optimized and designed generally in the factory and is small in size as a result. With skid-mounting is used, the equipment is made into an entirety; therefore, the equipment can be moved and relocated conveniently.
2. Integration ratio is high, installation in place is achieved and convenient maintenance is realized.
The loading skid integrates a controller, a flowmeter, valve, a pipeline, an accessory equipment, a crane pipe, a middle connecting piece, cables, cable trays, etc., and the loading skid can be installed conveniently on site as well as maintained and repaired easily.
The troubles of on-site installation are eliminated, cost is low, the construction period is short, normalization is high, error is less and materials are saved.
T he comparison between the loading skid and traditional on-site installation
Selection of types of the loading skid
Types of loading skid group:
In conventional use, loading skidding group can be divided into following types according to different mediums and loading-unloading methods:
A. Bottom loading skid-mounted group
B. Top loading skid-mounted group
C. Mobile-type loading skid-mounted group
The bottom loading skid-mounted sets
Alkanes, ammonia, hydrocarbons, ethers and other closed skid-mounted
