Announcement: P-D and BRCC long-term exclusively distribution alliance


JIAOZUO BEIXING REFRACTORIES CO., LTD (BRCC) and the P-D Refractories Group (PDR) have established  a long-term and exclusive sales alliance, cooperating in the fields of manufacturing, distribution and the further development of special refractory materials, such as silicon carbide (SiC), light weight insulation firebricks, carborundum ramming materials, high alumina castables and graphite products for the global aluminium industry.
Extensive long-term groundwork leading to this cooperation has now reached a synergy between the two companies, resulting in a synchronization of our quality control and R&D departments. By sharing our know-how, we can now assert that products from our Chinese partner are of the same high quality as of those our customers expect from the P-D Refractories Group.

Since November 20th 2018, marketing and the accountability for technical support and sales, have now been divided into regions: BRCC focusing their marketing activities mainly in China and a few outlying regions, PDR focusing worldwide, but excluding the above mentioned BRCC fields of operation.

This alliance allows us to provide our customers a complete package of refractory products for aluminium reduction cells, thus simplifying the tendering and ordering process for our customers and ultimately resulting in considerable cost reduction.

We are delighted to make this new announcement and are looking forward to our new joint venture.

P-D Refractories congratulates P-D Valmiera Glass USA Corp. for the successful inauguration of the fiberglass bath


In December 2017, the Ɛpsilon Solution™ basin delivery in P-D fused mullite was concluded and then, as reported on site by Mr. Uwe Pottetz, Project and Product Management P-D Glasseiden GmbH Oschatz, it was “wonderfully” heated. The heating of the floor and the basin of the bath quickly reached an even temperature, owing to the superior energy radiation of the Ɛpsilon basin. Now that it has been in use for a few months, the energy consumption to date is proving to be significantly lower than expected! We are delighted, Ɛpsilon is an excellent solution for us!

Under the direction of Valmiera Glas AG, a new fiberglass plant was built up in Dublin/Georgia USA within two years, from the planning to the opening on April 11, 2018.

On January 30, 2018, the first fiberglass was produced. A great performance that is unique in the world. Valmiera Glas AG as the main shareholder and the P-D Group have a long-term cooperation on the US market. For the Valmiera Glas stock company and its shareholders it is a further step forwards.

Record – hand-moulded drip rings made in Bochum

PD Refractories News

Hand-moulded drip rings ensure that a correctly dosed bottle of the right size and quality is made out of each drop of glass. This is a very critical product for glass makers, as quality and durability are of exceptional importance.
After relocating the manufacturing of hand-moulded drip rings from the former P-D plant DYKO in Düsseldorf in 2014 to the “Bochum hand-moulding” team at the P-D Dr. C. Otto plant in Bochum Dahlhausen, an annual record was set in Bochum in 2015:

On 14 December 2015, Mr. Helder Pereira Domingues showed the 7000th two-hole drip ring he had manufactured.

Whether single-hole, two or three-hole, our drip rings are guarantee durability. Whether they are made of zirconium mullite or corundum, only hand-moulded and highly densified drip rings guarantee superior heat corrosion resistance. With these products, hand-moulded and made in Germany, we are contributing to the profitability of glass bottle manufacturers.

Resumée Glasstec 2012

P-D Refractories | Glasstec 2012

The leading global exhibition for the glass industry – the glasstec 2012 – took place in Düsseldorf from 23rd to 26th October. Although the volatile economical situation also effects the global glass industry, this year’s glasstec set a clear and optimistic sign into future. This positive balance is drawn up by the representatives of the glasstec – and so do we!
The duties arising from the economic slowdown in the glass industry are clear: saving resources by energy and cost efficiency. Exactly this point is taken into account, by our activities and product developments which we presented at the glasstec: Our concept “Low-E Crown” for the lining and insulation of crowns of glass furnaces leads to a reduction in heat loss of at least 25%. In addition to this new concept, also our new solutions in areas of soldier blocks and tank superstructure generated positive response.
For further information please use the link to our exhibition newspaper.

To provide an easy access to our new developments we built a counter that was set on a lying crown, soldier lining and superstructure of a glass melting tank.
This 16 sqm exhibit led to great surprise and much discussion with our visitors.
