Valve manifold is intended for routing, discharge and pressure measuring of the water which is injected to injection wells of the pressure maintenance system (PM).
Valve manifold can be performed in macroclimatic areas with mild (M), and boreal (B) climate as well as in areas with frigid (F) climate. Climatic modification of the valve manifold is chosen regarding the developing area according to the GOST 15150-69 standard requirements.
Explosion hazardous zone class is B1a. Process unit is assembled beyond explosion hazardous area.
Valve manifold consists of two units: process and instrumentation units. VM is fulfilled in modular construction. VM construction meets OST 26.260.18-2004 “Process units for gas and oil industry. General technical conditions”. The unit’s equipment is assembled in a heat-insulated house. Block-boxes are fulfilled on a welded basis (the basis material – steel shape) with fencing.
Process unit encloses:
- Discharge (general) manifold;
- Head conduits;
- Drain system with drain manifold;
- Shut-off and control valves of the manifold, conduits and drain system;
- Automation sensors and annunciator (on automation and conduits);
- Ventilation and lighting system.
The technological house electric equipment (house heaters, lighting, air conditioning, sensors) control is performed by a control cabinet of the instrumentation unit.
For the service to be convenient VM is equipped with manometers on every discharge pipe and with interconnecting walkway above discharge pipes.
VM unit components and its positioning options are determined by the customer according to the technical data sheet or the design engineering assignment.
