Hermes-Ural LLC produces elliptical heads, an important component of reservoirs operating under high pressure. An elliptical head with flanged edges is used for tanks, vessels, and boilers of various modifications. These plants are intended for oil-and-gas and oil refining, agricultural, food processing, chemical, and other enterprises.
Hermes-Urall heads can have a base with a diameter of 1 to 3.4 mm and wall thickness of 0.4 to 2.6 cm. Actual dimensions are chosen based on the climatic conditions of operation, materials, and a number of other factors.
Elliptical heads are made of steel selected in accordance with GOST 34347-2017 and individual calculations considering the system pressure, characteristics of the medium, maximum and minimum temperature of the conditions a tank, vessel, or machine operates.
Manufacture employs the cold forming technique. As a result, the customer gets a durable stainless flanged accurately designed unit (dimensional deviations do not exceed 1%) with a flawless surface.
- Designing parts in accordance with the expected operating conditions.
- Production of elliptical heads, tanks and vessels according to the specified dimensions.
- Quality Assurance of end products.
- Product testing in the accredited laboratory.
- Delivery of standard-size and oversized cargos all over Russia.
- Large-scale production capacity. The manufacturer makes flanged and non-flanged products of stainless steel, carbon steel, and other types of steel. You can order receivers, LPG, industrial separators, and products of other types in any volume.
- Guaranteed quality. Since Hermes-Ural’s production plant is furnished with certified European equipment, we can guarantee the high grade of any product we manufactured. The minimum warranty period for an elliptical head of any type is 18 months.
- Flexible approach. Products can be manufactured using materials provided by the customer or Hermes-Ural (stainless steel, carbon steel, cold-resistant steel), according to customer’s ready-made drawings or specifications. Our extensive experience allows us to develop optimal solutions even in intricate situations—to provide customers with the appropriate, desired result.
Heads are made without side cutting, heat-treated, with high tempering.
We can cut the side with chamfering for further welding according to the customer’s design documentation, and weld the central technical hole on heads 1000-8-250 and 1200-8-300 with 100% ultrasound inspection of the seam.
Extreme head size and shape deviation:
- deviation of the inner/outer diameter of the cylindrical part of the flanged bottom: no more than +/- 4 mm
- relative ovality: up to 1%
- thinning: up to 15% of the initial thickness
- other specifications are compliant with GOST 34347-2017
The warranty period is at least 18 months from the commissioning date, but not more than 24 months from the date of shipment from the manufacturer.
