A medium sized well cover with some big features The 180 Nondo cover contains a high quality machined cast iron lid and base, with a strong plastic skirt. It is ideal for 50mm monitoring wells and has been tested to exceed load bearing requirements for traffic suitability for Australian Standard AS3996 Class D. The small 180mm OD makes it ideal for drillers who typically use a 200mm concrete corer.
General principles The Shelby sampler is a thin-walled soil sampling system. The system is used to sample soils that are particularly sensitive to sampling disturbance, as it has a very low wall thickness-to-sample area ratio. The sampler consists of a thin walled steel tube whose lower end is shaped to form a cutting edge.
Fieldtech Solutions is now stocking U63 and U50 Shelby Tubes and drive heads. Drive Heads are available in AW, AWJ, or NWJ box threads.
These pressure tanks are ideal for remediation projects where groundwater is to be treated with granulated activated carbon (GAC). Made of high performance composite materials, LLDPE liner with FRP filament winding outer shell, this design provides a continuous seamless inner liner shell with a fibreglass / polypropylene inlet for higher strength, temperature and pressure capabilities. A range of tank sizes are available (see table below) with diameters from 762mm to 1600mm. An LLDPE liner with FRP is also available for Industrial water filtration and softening applications. Flanged tanks are made with a continuos seamless inner liner shell with a solid anodized aluminium cast flange. This design provides excellent strength, durability and leak free service.
