Welded steel pipes
When considering the deliveries of welded steel pipes, we mostly do deliveries of longitudinally welded pipes and, to a lesser extent, of spirally welded pipes. When considering the dimensions and materials, our abilities are practically unlimited. In many cases we are able to offer welded pipes as an alternative to the seamless pipes, with the same characteristics and at a much lower price, and this is primarily related to the large diameter welded pipes (406,4 mm to 7000 mm), designed for extreme working conditions (e.g. at the plants for production of electricity and the facilities for processing crude oil and natural gas). We have specialized in the deliveries of welded pipes according to API 5L specifications for gas pipelines of high, medium and low pressure.
| Minimum quantity: | Depending on the pipe type, it ranges from a single pipe to 10 tons per dimension. |
| Standards / materials: | According to all applicable national and international standards |
| Dimensional range: | 6mm - 7000mm |

Steel flanges and other forged parts
We started with a stock of welding neck forged steel flanges. Today, in addition to the stock-sale, we are also able to provide flanges and other forged pieces according to project’s / client’s specific requirements.
From the moment you submit a drawing of the required part, to putting the signature on the purchase contract, together we look into a range of issues relevant for obtaining a quality product. After the contracting, and if necessary, we are able to provide: A preproduction inspection of the equipment and the quality of raw materials, the production inspection and the final inspection, which consists of monitoring the process and writing the results of factory tests, testing / comparing the documents and goods according to the type and quantity, and checking the dimensions and tolerance on a series of samples.
Inspection can be done in two ways: either on-site or through the exchange of relevant documents (with the recognized suppliers).
| Types: | See references and stock-sale |
| Dimensional range: | DN15 - DN 5000mm |
| Minimum quantity (from the stock): | 1 pc. |
| Minimum quantity (from the production): | 1000kg |
Other
Sheets, hot-rolled profiles, reinforcing steel bars, square and rectangular welded pipes, welding powder and welding wire.
| Standards / materials: | According to all applicable national and international standards |
| Min quantity: | Depending on the manufacturer’s conditions |
