Large Diameter Pile Casing Manufactured in the UK
Large diameter pile casing can be supplied by John Lawrie Tubulars in up to 914 mm diameter x 2.7m effective lengths. Our standard range of rotary casing is as follows but contact our team to discuss options further.
Pile Casing is used as a support structure for a bored piling system, it can be permanent or temporary. It’s typically used when deeper, unstable soil conditions are present. Our repurposed steel pile casing is manufactured (in-house) from surplus or redundant steel tubulars (sourced form the oil and gas industry). We design, manufacture and supply large diameter and micropile casing pipe which is normally utilised during the drilling stage of construction. Once installed, the tubes are filled with concrete / reinforced steel to offer connection to the reinforced foundations, which are cast on top.

Frequently Asked Questions
The tubulars arrive at our yard mainly by lorry but occasionally also unload containers. The loads go across the weighbridge before being taken into the yard to be unloaded. The tubulars are visually inspected for any noticeable defects or excessive wear. Wall thickness is checked to make sure it meets our specification. Material is then split into carbon steel or %CR material. Any material which requires cleaning is put to our high-water pressure cleaner before going to storage bays awaiting an order.
We operate two fully automated saws for the cutting of the tubulars to the customer’s specifications. The tubulars require cutting for many reasons including access at the site or the pitch of the rig. We have also had custom made machined spud joints manufactured for use with plain end pipe.
John Lawrie Tubulars have a large inventry of stock on the ground and take pride in our close working relationships with our haulage companies. We can deliver to site as quickly as the next working day!
For the safe and easy unloading of steel pipe at site, we offer customers the option of having the pipe slung with fully certified slings prior to departure from our operations yard. For orders where shorter material is required – 2.5 meters and under – we palletise the load.
