Oil and Gas pipelines are used in harsh environments and regular cleaning of the pipelines prevents the build-up of waste in the pipelines, improves the total flow and efficiency of the system and also helps to prevent corrosion and other forms of damage. The cleaning pigs are designed to clean pipes effectively and usually contain many powerful giant neodymium magnets.
The powerful permanent magnets are a vital component in cleaning pigs. They have high magnetic force, capable of attracting ferrous debris from a distance. They are usually in the form of components for easy mounting. The use of multiple rows of magnet boxes in the cleaning pigs is to ensure that they cover the maximum internal diameter of the pipe.
The neodymium magnets have higher remanence, coercivity, and energy product, increasing magnetic force and making the product more compact. But they are sensitive to oxidation and require surface treatment, like NiCuNi.
NdFeB magnets are available in various temperature ratings, from 80-220ºC. The specific application determines the choice between ambient and high-temperature magnets. The current range of magnet materials for pipeline cleaning pigs includes grades N35 and N42 (80°C), N52 (60°C), N50M and N52M (100°C), N40H, N48H to N52H (120°C).
While expensive, the benefits of utilizing neodymium magnets on pipeline cleaning pigs far outweigh the cost, as they can remove ferrous debrisfrom a pipeline, ensuring the line is ready for an In-Line Inspection.
Ferrite magnets are another type of permanent magnet used in cleaning pigs, with low cost and high corrosion resistance. Though not as powerful as neodymium magnets, their high coercivity and low cost make them ideal for high temperature applications.
The most common shape of the permanent magnets we currently produce for pig accessories is in block form. However, if you require segment or round magnets, we can customise them to your specific requirements.
Strength testing of neodymium magnets for cleaning industry:
Following is our standard sizes for your choice, if there is no size you need or some different requirement, please contact us.
Shipment: Magnet can be shipped by Air, Express, Truck and by sea. But it must be shielded if by air or Express.
How to promise the quality: Quality is our culture! To ensure our quality, all magnets are produced with 100% new standard material rather than recycle or bad material. Besides our professional QC department will inspect the magnet for each stage, including magnet grade, coating, dimension, tolerance and pulling force for pot magnet, magnetic hook, fishing magnet or other magnetic assemblies. So that our magnet pass rate is as high as 99.5%.
Feedbacks on our magnets
Testing reports of magnet
Sample:Sample of magnet is available to provide within 2 days if we have it in stock. Otherwise, it takes 7days to produce.
MOQ of rubber coated pot magnet: Usually we don't require special MOQ of regular size for you, small order is available to accept. If you ask for special custom size and it needs mold to produce, MOQ is decided according to detailed product.
Custom service: Custom service is our advantage. Multimagnets has a professional technical team to support our customers. We can provide professional CAD drawing, strength simulation of magnet / pot magnet, even that Multimagnets can assist you to design a new magnet. For some Amazon customer, Multimagnets always provide free labeling and professional photos taking.
