Setting Flange 1 Carrara, gaskets with value Always ask the best. Carrara gives you more Carrara believes in the modern SUPPLIER meaning: active subject that actively takes part in the value chain! A value that emerges from: competence, flexibility, innovation and availability, always being oriented to the customer’s necessities and the continuous interaction with them. Thanks to the experiences made in the field of the seals systems for flange, Carrara proposes a very complete and eterogeneous Product Range of flat and metal gaskets. For the most general applications as for the most severe...

2 Carrara, a partner for the future Carrara S.p.a. is one of the most important worldwide packing producer and of operating seals systems for valves operating in the western world. With quality as always, Carrara also produces flat and metal gaskets. While many other Big Players of the sector move their production activities in other areas, Carrara S.p.a. invests in Italy and in the European Community, because it considers that the customers of this mature market want and will want to buy, integrated with the product, also attributes that are and will be essential prerogatives of this...

Setting Flange 3 Certainty In a market strongly Price Oriented, the risk of a progressive reduction of the qualitative standards is always present. The certainty to have bought the corresponding product to the requested qualifications is a customer's right and a duty of the Supplier. Guarantee Guarantee means keeping control on the productive process and those where the product is involved to guarantee the conformity to certify their performance. Efficiency Efficiency means to manage the production process and those correlated to the product optimizing the resources in order to create value...

6 Planigraph® Competitive quality Whoever manages daily graphite products, a quick glance is enough to notice the difference between two gaskets from different production, apparently equal. The CARRARA S.p.a. products are always identifiable and certified. Just by touching it you notice the intimate adhesion between graphite and steel of the reinforced product and the extreme compactness of the product in pure graphite. Carrara offers performance, not only product. Carrara S.p.a. products are recognizable by colour: green identifies LG/C, rose identifies LGR/C and blue identifies LGRF/C....

Setting Flange 7 The pure graphite without insertion The gaskets in pure LG graphite are perfect for applications on flanged couplings at low pressure or used as a seal element with a metal support. The pure graphite has poor resistance to traction; therefore it is always advisable the use reduced thickness (by 0.4 to 1.0 mm) to obtain a perfect seal. Planigraph® LG Size 1.000 x 1.000 40” x 40” 1.500 x 1.500 60” x 60” Thickness 0.4 ÷ 5.0 1/64” ÷ 3/16” Not usable with oxidizing stream. With oxygen and air, the maximum temperature is 400°C.

8 The pure graphite with smooth insertion The gaskets in pure LGR graphite offer excellent performances in the applications on the Bonnet of the valves and for flanged couplings of heat exchangers. A better resistance to the permeability can be obtained with the internal edge of the gasket. To obtain a perfect seal with this kind of gasket, the thickness use of 1.5 mm is recommended. Planigraph® LGR Size 1.000 x 1.000 40” x 40” 1.500 x 1.500 60” x 60” Thickness 0.4 ÷ 5.0 1/64” ÷ 3/16” Not usable with oxidizing stream. With oxygen and air, the maximum temperature is 400°C.

Setting Flange 9 The pure graphite with tanged insertion The gaskets in pure LGRF graphite are the most versatile and of universal application on the flanges and flanged couplings of heat exchangers. A better resistance to the permeability can be obtained with the internal edge of the gasket. To obtain a perfect seal with this kind of gasket, the thickness use of 2 mm is recommended. Planigraph® LGRF Size 1.000 x 1.000 40” x 40” 1.500 x 1.500 60” x 60” Thickness 0.4 ÷ 5.0 1/64” ÷ 3/16” Not usable with oxidizing stream. With oxygen and air, the maximum temperature is 400°C. Graphite density...

10 The protection ring Planigraph® Metalbond is a Planigraph® gasket, with an inside reinforcement ring that increases the effectiveness of the seal, a solution that allows minimal spread of the fluid through the most stressed part of the gasket. Economy and long duration The steel ring prevents the erosion of the inner edge of the seal and at the same time precludes the infiltrations between the graphite and the reinforcement sheet. Since the graphite does not enter directly in contact with the fluid, the mechanical property of the seal remains unchanged within the time. A longer operating...
