Upcopming Webinar: Repairing the Irreparable

Advanced in-situ machining and metal-stitching repair solutions

 

In the marine sector, every time a machinery component is worn out or damaged, an important decision needs to be made: To either repair or replace the component with a new one.

Factors such as technical or operating possibilities, lead time for a replacement component, size or weight of the damaged component, the downtime required for the replacement works, loss of revenue, cost of the repairs etc need to be carefully evaluated before deciding to repair or replace a key component with a new one.

Join QuantiServ and Wärtsilä on the 7th of July 2021 at 14:00SGT to explore:

  • Possibilities and benefits of repairing a damaged machinery component with advanced in-situ machining, instead of replacing it.
  • Possibilities and benefits of repairing a damaged machinery component with metal stitching, instead of replacing it.

Key Data 2020 – Number of Customers and Orders Increased

We have steadily grown our reach and our customer base during recent years. In 2020, our 356 staff have successfully processed close to 3’000 Reconditioning, In-situ Machining, Metal Stitching, Epoxy Resin or Mobile Team orders from nearly 700 individual customers.

We carried out 70% of these orders in one of our 14 workshops. The remaining 30% of orders we processed on board ships or in customers’ plants.

The customers that we served stem from a wide range of industries. On average, we commenced a new in-situ machining assignment every three hours, anywhere in the world.

Metal Stitching: Why we Use the Best Stitching Pins in Existence Today

The Castmaster stitching pins that we use for our metal stitching repairs are manufactured by Lock-N-Stitch in the United States. They feature the patented Spiralhook thread, which makes them the best choice to carry out very strong, permanent metal stitching repairs.

This animation shows the working principle of the Spiralhook thread and explains why, unlike other products, these stitching pins do not create a radial spreading force during tightening.

 

These stitching pins are available in various diameters and lengths and are suitable to repair cast iron, steel, aluminium and bronze parts that are from 4 to 200 mm (1/6 to 8 inches) thick.

QuantiServ at the Sea Asia 2017 Exhibition in Singapore

Sea Asia Exhibition 4Our participation at the recently held Sea Asia 2017 in Singapore was a big success. We displayed our metal stitching and in-situ machining solutions, as well as the refurbishment of four-stroke cylinder covers by furnace brazing, which we are particularly proud of. These solutions created quite a lot of customer interest and led to many interesting discussions.

Our next stop will be the Norshipping Exhibition in Oslo, 30 May – 02 June 2017, where we will be at booth D 05-34. Come and visit us there.

No job too small – if it solves the customer’s problem

A ship’s crew received a new cylinder liner in a mid-eastern port. Unfortunately, while lifting it onto the vessel, a sling came lose and the liner crashed hard on to the deck. Luckily no one was injured, but it caused a piece of cast iron at the circumference to be chipped off, rendering the liner unusable.

Instead of scrapping the liner, the Superintendent contacted QuantiServ and sent us pictures. After we confirmed that we could salvage the liner, he shipped it to our workshop in the Netherlands.

There our skilled machinists milled off a section of the liner and confirmed that there were no further cracks in the material. They then produced on a CNC milling machine a new piece that perfectly resembled the size and shape of the missing material. This they locked in place with glue and screws, thus saving a liner that otherwise would had to be scrapped.
