The Importance of Pre-Made Shims during your Outage

Having a premade set of shims for the diaphragm moves saves valuable resources

Precise quick diaphragm moves significantly shortens the diaphragm alignment duration, and having a pre-made shims kit accomplish that mission.

…We stock shim kits for several turbines, i.e. GE D11, GE C17, GE D9, GE G3.

Turbine outage success is determined by planning and preparation. Meticulous thought is put into a turbine outage months before it begins. Hard limitations are considered and mitigated to maximize the amount of work that can be performed per shift. These include:

  1. Crane Time
  2. Staging area space
  3. Labor Available
  4. Component rework/delivery timing

The internal alignment is one of the elements that is considered in this schedule. To complete an internal alignment, we can acquire readings and calculate diaphragm moves quickly. Then it comes time to move the diaphragms. Diaphragm moves can occupy crane time, staging area space and labor available. Often, valuable millwright time is spent cutting shim stock with tin snips. This process can consume hours and even shifts. Having a premade set of shims for the diaphragm moves saves valuable resources. A complete shim kit is important because only 2 to 3 shims should be used underneath each key. Precise quick diaphragm moves significantly shortens the diaphragm alignment duration.

ACQUIP Shim Kits
Turbine Shim Kits

ACQUIP can provide a premade shim kit for your diaphragm alignment, saving you time and resources. Don’t pay skilled labor to cut shim stock when they can be moving the internal alignment off the critical path. We stock shim kits for several turbines, i.e. GE D11, GE C17, GE D9, GE G3. If we don’t have your diaphragm shim sizes you can send us a drawing and we can make a kit within 8 business days or expedite in as few as 3 days. Kits are in their own boxes and labeled for each thickness.

All shims are 302/304 Stainless Steel and profile tolerances are within 0.005” contact us for more details. Info@acquip.com +1 305 538 7101.
