Equipment skids

Piping, valves and actuators in a process plant, next to a walkway with handrail

A plant that gets built in the shop

Skid (noun): a steel frame on which equipment, piping and instruments are mounted so they can be moved and installed as a single unit. That is the dictionary definition. What it leaves out is the important part: a skid is a way of moving work from the field to the shop, where it gets done better, faster and under a roof.

At Indumor we build the frame: welded structural members, machined pads for each piece of equipment, engineered lifting points, a tray or supports for the internal piping, and the coating the destination calls for. Your plant or your integrator mounts the pumps, motors and panels; or, if you prefer, we deliver it with the shop-built piping included.

The skids we build

Pumping and transfer

Frames for pumps with their motors, valves and suction and discharge headers.

Dosing and filtration

Compact skids for chemical dosing or fluid filtration, with drains and a drip pan to contain spills.

Compressors and hydraulic units

Rigid bases for vibrating equipment, with leveled pads and anchor holes that match the civil drawing.

Complete pump rooms

Several units with their piping on a single frame, ready to lift, set and connect.

What the drawing says and what happens in the shop

On the drawing

A frame has to carry the weight of the equipment and the operating loads: vibration, pipe thrust, motor start-up. With those numbers the members are selected, and the calculation closes.

Why in the shop

Field hours are the most expensive and the slowest: wind, dust, scaffolding and a crew waiting for the crane. In the shop the same work is done on a level floor, under an overhead crane, with the welder within reach, and quality is easier to control. The skid is also assembled and checked complete before it ships: whatever would have shown up at commissioning shows up here, where fixing it costs far less. And if the plant changes tomorrow, it gets disconnected and moved.

Don't do this: weld the pads by eye and let the field crew align with shims. Every shim added on site is a misalignment the pump will later charge you for in bearings and seals.

What we need to quote it

  • Equipment list with weights, dimensions and anchor drawings.
  • Layout or piping diagram, if you have one.
  • Scope: frame only, or with shop-built piping.
  • Destination: indoor, outdoor or corrosive environment, to define the coating.
  • Lifting and transport: which crane lifts it and which truck carries it.

Frequently asked questions

No. We build the frame and, if you ask for it, the shop-built piping. The equipment is mounted by your plant or the integrator, on pads that arrive ready to receive it.
Because welding distorts steel. Machined at the end, the surfaces where pump and motor sit end up in the same plane and the shafts align without shims.
Yes, that is one of its advantages: it gets disconnected, lifted by the same points and reinstalled somewhere else.
Whatever the destination calls for: an indoor pump room is not the same as an outdoor wellsite or a corrosive environment. The coating system is defined with you when quoting.

The best compliment a skid can get is that nobody talks about it on installation day.

It arrives, gets lifted, sits on its anchors and gets connected. Send us the equipment list and we will quote the frame, with or without piping. Or email tecnica@indumor.com.
