In-situ Machining is a service performed when the plant is off-line. It assists to renew a surface or surfaces, without having to remove the item.

Our in-situ machining services include:

  • Flange Facing
  • Flange flatness surveying
  • Milling
  • Journal Turning
  • Keyway Milling
  • Line Boring
  • Drilling and Tapping (including stud removal)
  • Pipe Cutting / Weld Prepping (including Pressure Vessels)

Flange Facing

Equipment to machine sizes from 0 – 126” (3.2 metres) diameter is carried in stock. Outside of this diameter, we have access to equipment through a supplier relationship.

Flange facing can be used on a multitude of applications. Traditionally it is used to re-machine flange or heat exchanger faces in-situ when they have become warped, worn or damaged. The newly machined surface then allows for an improved seal, preventing leaks to atmosphere.

Flange facers can also be used for machining manways, pump bases, crane pedestals, in fact any flat surface that is contained within the swing of the machine.

Flange Flatness Surveying

This service is generally provided utilizing a special surveying tool, such as a clocking arm or laser. Alternatively it can be provided using a flange facing machine.

Clocking arms are used to check flange flatness quickly and accurately. Once flanges are opened, visual inspection and flatness checking can be completed, allowing for quick identification of flanges requiring re-machining.

Milling

We mill surfaces up to 3m x 2.4m in size.

There are several different types of milling, from single milling beds to milling machines that travel in the X and Y direction, called XY Mills. Milling heads can also be attached to some of the flange facing machines for circular milling.

Typically milling is undertaken on surfaces that are out of flatness or surface finish. Milling these surfaces brings them back to their design or specified flatness and finish for the application at hand.

Journal Turning

We stock equipment for journal turning up to 12” diameter.

Journal turning is machining the outside diameter of a shaft to bring it within the desired specification for concentricity, surface finish, squareness and/or circularity tolerance.

Keyway Milling

Keyway milling is the cutting of a keyway into a shaft or other item.

We machine key ways in shafts up to 24" (610mm) outside diameter.

Line Boring

We stock line boring equipment up to 6” diameter bars. 6” diameter boring bars will machine up to approximately a 1 metre diameter bore.

Drilling & Tapping

Drilling and tapping equipment stocked provides the capacity for 2” threads to be tapped.

Drilling and tapping is used in many industries, from power to marine. There are numerous applications. In fact anywhere there exists the need to bolt items together using a blind hole.

Pipe Cutting & Weld Prepping

From 4” – 120” OD pipe cutting and prepping equipment is kept in stock. This enables from small diameter pipes right up to large diameter vessels to be cut and prepped in-situ, potentially saving enormous amounts of time and money in transportation of equipment.

Linishing

Linishing is the machining of tyre surfaces on kilns.

Custom Machine Build

BLJ In-Situ Solutions personnel are able to provide Specialised Machine Build services. This service can be required when an unusual application requires machining or restrictions make it impossible to fit a standard machine in the space provided.

This involves BLJ In-Situ Solutions personnel inspecting the item for machining, taking detailed measurements of the restrictions and scope and building a special machine to complete the job. Each machine would be quoted for either outright sale or for rental, subject to the needs of the customer.
