safety of DIAMANT products has been proven by practice and 

intensive laboratory test. 

The Russian oil company GAZPROM simulated the ageing of renovated defects under different 

mechanical impacts as pressure and vibrations as well as under weathering and thermal load. The 

studies resulted in a 10 year guarantee for repair areas in pipelines, valves, compressors etc. (full 

test report available on request; the summary is attached to this brochure). 

This brochure is aimed at exemplifying the application of DIAMANT products in the oil and gas 

industry as well as chemical companies. 

It also provides for each product group a short technical description. More detailed information can 

be obtained from our technical brochures which are available on request.

1. Sealing of corroded welding seams 

Leakages of welding seams of an empty oil storage tank have been repaired with 

UltraMetal Steel. 

UltraMetal Steel was applied on the exterior wall after thorough cleaning and roughening of the surface. 

Extreme protection is achieved by the following procedure with Dichtol and UltraMetal Steel: 

The cleaned and sand blasted welding seams are 

first impregnated with Dichtol which penetrates in the porosities (without pressure or vacuum) thus 

sealing them inside; after curing of Dichtol 

the remaining spot is then UltraMetal Steel applied. 

Example 1: 

The requirements were: 

longterm corrosion protection, resistance to gasoline, resistance to temperature cycles between –30 and 

60°C. 

The pressure resistance to 10 bar was checked by an independent test institute. 

Example 2:

2. Repair of pitching in a corroded storage tank with UltraMetal Steel 

The holes in the tank were closed with paste-like UltraMetal Steel P and glass fibre reinforcement. 

The surface was subsequently covered with a top coat of liquid UltraMetal Steel FL. 

3. Repair of a pipeline with UltraMetal ST (Superthixo) 

A gas pipeline with a wall thickness of 16,5 mm and diameter of 1320 mm showed corroded areas at the 

underside. The depth of the defects were 4 to 10 mm. The repair was carried out by the service 

company Spezneftegas (Russia) with UltraMetal ST (“Superthixo”) which provides a very high sag 

resistance. Curing was accelerated by a tent covering the spot and heating by a mobile heater to about 

50°C. 

4. Pump station – repair on oily surfaces with UltraMetal Rapid and Steel 

The renovations were carried out on oily surfaces with the special grade UltraMetal Rapid which is the 

ideal material for emergency repairs. 

UltraMetal Rapid has been approved by Lloyds.

5. Repair and long term protection of a storage tank with 

UltraMetal Steel, FlexCoat and ProChem 1931 

After repairing of the corroded areas with UltraMetal Steel, the outside of the tank was coated with 

FlexCoat. FlexCoat was specificly developed for large tanks which require flexible coatings due to the 

cyclical mechanical and thermal loads they are subjected to. 

For the coating of the inside of storage tanks – in particular the heavily corroded bottom of crude oil 

tanks – DIAMANT developed ProChem 1931. It offers the broadest resistance against a variety of 

aggressive chemicals. ProChem 1931 can be sprayed. Applications see below. 

6. Protection of large areas against chemical attacks with ProChem 1931 

Extreme protection of large areas is carried out with ProChem 1931 which offers the unique capability to 

protect against a very broad range of chemicals; i.e. highly concentrated acids, lyes and aggressive 

organic compounds. 

ProChem can be sprayed with a 2-component spray equipment at about 50°C and 300 bar. The photos 

below show a tanker for the transport of concentrated sulphuric acid and the coating of an exhaust 

system which is operated at 155°C.

7. DIAMANT pressure tests of 

UltraMetal 1250 on oily surfaces 

Hole sizes between 6mm and 26mm were filled in a special process. Pressurizing until burst was 

videotaped enabling DIAMANT researchers to analyse and optimize the safety of the materials. The burst 

pressure ranged between 150 and 250 bar. 

Further systematic studies have been conducted investigating the parameters which have an impact on the 

burst pressure. Based on these tests, DIAMANT can provide a great deal of Know How and technical 

support to its customers. 

8. Extreme repair with DIAMANT products at Gazprom 

The Russian oil- and gas company GAZPROM tested the reliability of extreme repairs as shown below: A 

hole in a corroded test specimen was widened to a slot. A steel reinforcement was introduced inside and 

fixed with UltraMetal Steel. The tube was then pressurized and simultaneously subjected to mechanical 

impact. 

Long term tests showed crack forming only after a few years at a pressure above 100 bar (see also attached 

summary of the test report).

9. Pump and valve repair 

A broad variety of pumps and valves have been repaired with DIAMANT materials. 

9.1. Repair of a crack in a valve with UltraMetal Iron 

The pictures show the preparation of the repair area by widening the crack V-shaped, drilling holes at the 

end (to avoid propagating of the crack) and sand roughening of the surrounding surface. UM Iron was 

then pressed into the gap and onto the surface. 

9.2 Precise adjustment of a shaft with PlasticMetal Steel 

MM 110, 

DIAMANT PlasticMetal products are composed of metal powder and hardener liquid which can be 

mixed in a free mixing ratio to a viscosity fitting exactly the individual requirement. Due to the fast curing 

within one hour, the precision adjustment of the loose shaft could be done within 1,5 h altogether. 

9.3. Repair of a heavily worn housing with PlasticMetal Ceram or UltraMetal Ceram 

Extremely worn casings can be repaired with both, PlasticMetal Ceram or UltraMetal Ceram. 

Repaired areas often show a longer service life than the original parts due to the firm embedding of 

special ceramic fillers. 

PlasticMetal products have a much faster curing in addition to the free mixing ratio whereas 

UltraMetal Ceram is more resistant if the repair-area is subjected to high mechanical impact, vibrations 

and cyclical loads. UltraMetal is also preferred if the repair spot is larger than 100 cm 2 . 

The photos show the repair of an extremely worn housing with PlasticMetal Ceram and a steel mesh 

reinforcement which is additionally fixed with screws.

Cast Iron, Steel and Ceram 

The UltraMetal series consists of cold curing 2 component polymer systems with selected fillers. 

UltraMetal has an excellent adhesion and almost no shrinkage on curing. 

As a result there is no tension in the repaired area and it is the ideal material for machines and equipment 

which are subjected to mechanical stress or vibrations and the like. As the processing time is at least 40 min 

UltraMetal is also the preferred material for large areas. 

UltraMetal Iron and Steel are general purpose materials for high quality repairs of iron or steel respectively. 

UltraMetal Ceram provides a long term wear resistance due to firmly embedded ceramic fillers.

Cast Iron and Ceram 

The PlasticMetal series consists of a liquid hardener and a powder containing metals, fillers and additives. 

Both components can be mixed in a free mixing ratio. 

As a result almost any viscosity from liquid to paste can be mixed with one package. 

Further advantages are the high chemical and thermal resistance. Due to the short curing time PlasticMetal 

is mostly used for smaller areas. The repair spots can be machined after half an hour. 

PlasticMetal Ceram is a special grade for highly wear resistant repairs. 

DIAMANT offers a great variety of further metal powders and special hardeners to meet individual requirements 

(see technical brochure).

Dichtol is a one component ready-for-use liquid with the unique property to seal microporosities and hairline 

cracks without pressure or vacuum. 

Dichtol is simply applied by brushing, spraying, dipping or filling the item to be impregnated. As Dichtol 

seals inside, the surface film can be removed without loss of tightness. Consequently, Dichtol is the ideal 

material for the impregnation/sealing of parts which are subjected to severe chemical and mechanical 

conditions on the surface. 

Dichtol Standard seals porosities up to 0.1 mm; 

Dichtol Macro up to 0,5 mm. 

The WF-grade has an improved thermal resistance. 

Dichtol HTR is resistant up to 500°C continuous load. HTR is the only grade which requires annealing at 

250°C for a few hours after application. 

Dichtol is being used in the industry for decades. It has been approved by a lot of classification societies as 

well as public and private research and test institutes.
