What do you do with used thread protectors? Do you put them to landfill? That is a costly exercise. And environmentally damaging. Most operators in the North Sea use Norkram as an alternative to landfill.
Not only is it a more cost effective way to dispose of thread protectors, but it also guarantees that none of them go to landfill. You can rest assured that they will either be reused or recycled.
Process
- Protectors are received in containers from an off-shore location
- Containers are emptied by our operators
- Contents are sorted by:
- Connection Type
- Size
- Colour
- Manufacturer
- Pin / Box
- Good / Damaged
- A report is then sent to the customer detailing their returns
- Customers are only charged for protectors why we can’t reuse.
Key Features & Benefits:
- More cost effective than landfill
- Environmentally-friendly
- Goes towards your ISO 14001 accreditation
- For purchasing, refurbished protectors are better value compared with new products

The Norkram brushing and coating unit is a portable solution for the removal of external rust, loose coating & scale and applying a UV cure coating (Mill Varnish) on your pipe, on-site, anywhere around the globe.
When pipe is stored for long periods of time in an outdoor space, it will inevitably rust and potentially loose traceability. The usual method of refurbishment is to have the pipe transported offsite for either brushing or shot blasting and then coating. It then needs to be loaded and transported back to site. This is a lot of handling and transport.
With the Norkram brushing and coating unit, all of this can be done on site which negates the need for excess transport and makes the process quicker and more cost effective. Also maintaining traceability of the pipe markings back to Mill Certificates is essential.
With the use of UV light technology, our coating will cure in minutes ensuring that when the pipe has passed through, the coating will be completely dry, protecting the pipe and the markings.
As the unit is completely containerised, Norkram can transport it easily to your pipe yard anywhere in the world and complete the rejuvenation of your pipe in a quick and efficient manner without having to handle pipe more than is necessary, saving time and money.
Key Features and Benefits:
- On-Site brushing and coating – No need for unnecessary handling or transport
- Fully transportable and compact
- Cost effective
- Protecting the pipe and the mill markings
- Thicker than mill applied coating – longer lasting protection

Bumper rings are another form of pipe protection product designed to stop pipe from touching / banging together along the the body length during transport and handling / bundling.
Our bumper rings are manufactured on-site and are made from the plastic which we recycle from thread protectors. This ensures that the plastic we use is of the best quality given it’s previous use. And is environmentally friendly given that there is no waste and no miles attached to the plastic (meaning almost carbon neutral production given there is no transport for raw materials)
Construction
The bumper ring is coiled plastic construction and is made to fit snugly around the pipe. This ensures there will be no contact between pipes meaning no metal to metal contamination.
The design of our outer profile also means that the ring is extremely stable on the pipe and does not spring off.
The material is predominantly HDPE which is from our own recycled stock.
Types & Colours
Unlike thread protectors, bumper rings do not have any kind of connection compatibility issues. But they can come in different thicknesses and heights to help protect:
- Large OD Couplings
- Centralisers
- Tool Joints
- Down Hole Tools
With the above in mind, we can manufacture bumper rings to customer specifications. They can also be manufactured in a range of corporate colours.
Sizes
The size of the bumper rings correlate directly to the outer diameter of the pipe. If the OD of the pipe is 13.3/8”, the ID of the bumper ring will also be 13.3/8”.
Sizes range from 2.3/8” up to 20” and all sizes in between. As mentioned above, we cam manufacture ID’s specific to customer requirements.
Key Features & Benefits
- Protects pipe from damage in transit or while bundling
- Designed to be very stable on the pipe body
- Manufactured from excellent quality recycled material
- Can manufacture bumper rings specific to your needs

A thread protector is a screw on cap that helps prevent damage to the threads of OCTG and drill pipe.
The types, designs, and manufacturers of thread protectors are many and varied, and we have refurbished most of them.
Open End / Driftable 
Closed End, Non-Liftable 
Closed End, Liftable
Types of Thread Protector
- Open End – where the threads and pipe ends are protected but the bore of the pipe is open to the atmosphere. These are primarily used for protecting the thread during shot blasting or cleaning the bore, or for drifting the ID of the pipe.
- Closed End Non-Liftable (CENL) – which protect the thread and pipe ends, and also prevent any ingress of water, moisture and debris by sealing the pipe ends.
- Closed End Liftable (CEL) – which are the same as the above, closed end protectors, but also allow the pipe to be lifted using pipe hooks
Pin & Box
There can be some confusion about pin & box terminology when it comes to thread protectors:
- PIN – Male thread on pipe
- PIN PROTECTOR – Female cap which screws onto the male pipe thread
- BOX – Female thread on pipe
- BOX PROTECTOR – Male cap which screws into the female pipe thread
