Modular Bolted Steel Storage Tanks

Richard Alan’s range of bolted, glass fused-to-steel, fusion-bonded-epoxy and stainless steel tanks, for water, liquid & dry bulk storage

As existing customers will know Richard Alan has manufactured cylindrical welded steel tanks, silos and pressure vessels for many years and this comes as a natural extension of its range, adding the ability to service greater storage volumes with an on-site, bolted, modular steel tank product.

A range of products is available with glass-fused-to steel, fusion-bonded-epoxy and stainless steel options being offered, along with a full range of tank roofs and the ancillary items that have been provided on its welded tanks for years. Pipework, access steelwork, launders and distribution chambers, all provided in-house.

These new products meet or exceed expected industry specifications and design life requirements, with the added benefit of Richard Alan’s outstanding reputation for customer support, first-class engineering, project delivery and safety.

Sales and engineering teams will work closely and collaboratively with clients to deliver competitive packages, incorporating the full range of Richard Alan products in order to provide enhanced value to the end user and reduce the number of sub-contractor interfaces on site.

Richard Alan’s Glass-Fused-to-Steel Tanks (GFS) are produced in partnership with a leading manufacturer and have been proven over many years to provide excellent service and design life with the minimum of maintenance.

This is the only tank finish where two materials are fused together to take advantage of the properties of both materials; the strength and flexibility of the steel combined with the corrosion resistance of the glass. The high-temperature fusion of glass to steel through a furnace results in an inert, durable finish.

GFS tanks can be supplied with DWI-approved coatings for drinking water applications and fully comply with the newest industry quality standard ISO 28765:2016.

The range of Stainless Steel Bolted Tanks has been developed in response to a growing demand for a large-volume steel tank solution that is not dependent on coatings but still offers a high level of corrosion resistance.

Whilst there has been a preference for Stainless Steel Bolted Tanks in certain industries over the years (food processing, distilleries, breweries, etc.), Richard Alan has witnessed an increasing demand outside of those industries, in particular on Biogas schemes with very specific requirements.

Applications such as Buffer Tanks, Pasteurisation Tanks and the Gas Zone in Primary Digesters are particularly suited to this solution, which provides the speed of on-site installation associated with a bolted tank, but with increased levels of corrosion resistance.

Richard Alan’s Fusion Bonded Epoxy coated steel tanks are manufactured in partnership with world-leading coating specialists to ensure that, through continuous technology and process improvements, only the finest epoxy coating available in the industry is achieved.

Fusion Bonded Epoxy (FBE) coatings offer a very durable and cost-effective option to GFS technology and are becoming a popular choice for many applications.

Richard Alan offers a range of Tank Covers, each designed to suit the client’s specific application.

The GRP Conical or Beam & Infill Covers are produced in partnership with leading GRP manufacturers in the UK, providing a quality tank cover for odour control.

Glass-Fused-to-Steel & Stainless Steel Roofs are available for Anaerobic Digestion applications, where the loading requirements and corrosion resistance may exceed the limits of GRP.

Aluminium Geodesic Domes are offered as highly-engineered alternatives to GRP and provide maximum durability with minimum maintenance cost. The low weight of the aluminium dome roof has a decisive cost advantage, being designed to fit onto new and existing tanks, often without the need to be reinforced.
