Products

     In production unit of Ltd. “Valmiera-Andren" are manufactured vertical liquid storage tanks of glass reinforced plastic (GRP) in various diameter and volume  from 1m3 - 800m3, which mainly are intended for storage of chemicals with temperature range from -40°C up to +120°C. Diameter of reservoirs, manufactured in our plant, is up to 8 meters in diameter. 
The main application types of reservoirs:
Storage of chemicals
Storage of various types of water (drinking, fire fighting, rain, sewage)
Storage of food products
Storage of petroleum products (except petrol) 
Advantages of glass reinforced plastic (GRP) material: 
Excellent chemical resistance towards various aggressive substances, where other materials are non-persistent. High ratio of mechanic strength – weight. Small coefficient of thermal expansion. Long service life – excellent resistance to material aging and impact of atmospheric effects. Monolithic bulky constructions. Is not required often maintenance.  
Constructions:
Lower ends - flat, elliptical, conical
Upper ends - flat, elliptical, conical.
Cylindrical parts are manufactured with winding method, but attachments and connections – with contact forming method.
It is possible insulation of product with polyurethane foam plates, to which glass reinforced plastic is glued.
It is possible to provide electrical, water or steam systems for maintenance of constant temperature. 
Information, required for performance of product strength calculation and product cost calculation:

Desirable diameter or height of product.
Substance, intended for storage.
Location of product (in premises, external environment).
Actual size of working overpressure.
Actual size of working vacuum.
Actual temperature of working environment, °C.
Need for insulation.
Requirement of stairs, rails.
Painting requirements (colour).
