The HFP 36V uses only propane, no oxygen is required, reducing costs and reducing the total weight to carry on site.
The HFP’s built-in timer increases accuracy, improving quality and reducing the defect rate of weld due to preheating.
Providing a uniform preheat between the head and bottom of the rail reduces stress in the weld.
As the system is fully automated it is easy to use. Less training is required and it is straightforward for new welders to learn to operate.
The use of propane rather than oxygen results in significant cost and weight savings.
The preheater does not require any specific maintenance which makes it easy to manage during daily welding operations.
The HFP is a complete system that can be used to replace most existing preheating equipment.
The preheat technology used by the HFP is less sensitive to pressure adjustment than oxy-propane. It provides a uniform preheat between the head and bottom of the rail.
The HFP is fully automated, with automatic ignition, built-in timer and automatic stop. No manual flame adjustment is required.
The built-in timer can be pre-set by the welder for accurate preheating time.
2 long lasting batteries of 18V with 8.0 Ah, for a safer autonomy up to 8 – 10 preheats depending on the welding process.
The HFP system operates with propane rather than oxygen, saving money and weight.
There is a single torch height for all welds and no adjustment is needed.
With its compact size (L: 740mm, W: 300mm, H: 295mm) and light weight (19kg), the HFP can be easily handled by only one person.
Tested and approved against the European Standard EN 14730-1 Norm, the PLA Evo delivers improved metallurgical and mechanical behaviour, to optimise quality, lengthen the life of the weld and save time for the welder.
Performing checks and adjustments is an important part of the welding and maintenance process, particularly on the ends of rails.
AutoSeal® moulds are Pandrol’s newest aluminothermic welding innovation that streamlines the welding process.
HWR is suitable for repairing railhead defects between 25mm and 90mm wide and 25mm deep (depending on the rail profile), it can be used on both the parent rail and on electric flash butt welds, which often suffer from squats. It is also suitable for transversal defects, shelling and corner gauge. The aluminothermic weld process is carried out using specially designed moulds.
Beyond offering welding processes for all standard rail profiles, we also collaborate with customers to engineer bespoke solutions for special rail types that are less commonly used, such as the special rail grades used on metro lines including rubber-tyred rail, guide bar rail, conductor rail, and rack rail. We can offer portions, moulds and crucibles designed to your exact specification.
The process involves casting molten steel (produced through the reaction of iron oxide and aluminium) at a temperature exceeding 3,500 ˚F (1,950 °C) into refractory moulds designed to the rail specification.
This flat-bottomed rail is typically larger and designed to continuously support high volumes of weight.
Our vignole rail welding processes equip the user to perform new welds as well as wide-gap and head-wash repairs.
Pandrol Connect consists of three modules: a mobile version for welders to record on-site data and for welding controllers to review data, an online monitoring app to review weld information from the office, and an online administration tool to apply settings to local standards.
The ignition system is engineered to fit precisely into the round opening in the lid of the Pandrol Crucible. Once the crucible is prepped and ready to pour, the Startwel® Ignition System can be placed in the lid and deployed safely by removing the metal clip grounding the prongs.
