PRESSURE TEST BENCHES

Purpose:
Used to test the integrity, pressure capacity, and leak‑tightness of valves, fittings, hoses and pressure‑containing components.

Key Features:

  • Designed for hydrostatic and pneumatic pressure testing.
  • Available in manual, semi‑automatic, or PLC‑controlled configurations.
  • Equipped with high‑pressure pumps (air‑driven, electric, or diesel).
  • Pressure capacity up to 30,000 psi.
  • Integrated digital or analog pressure recording system for traceable results.
  • Includes safety enclosures, burst discs, and pressure relief valves.
  • Uses stainless steel tubing and fittings for corrosion resistance.
  • Provides low‑pressure filling and high‑pressure testing modes.
  • Compatible with water, oil, or nitrogen as test medium.
  • Fully skid‑mounted and portable for workshop or field testing.

Applications:

  • Testing of valves, flanges, BOPs, hoses, manifolds, and pipeline sections.
  • Factory Acceptance Tests (FAT) and Site Acceptance Tests (SAT).
  • Used in maintenance bases, OEM workshops, and offshore platforms.

Chemical Injection Skids

CHEMICAL INJECTION SKIDS

Purpose:
Used to inject precise amounts of specialty chemicals into pipelines and process systems for corrosion prevention, scale inhibition, and flow assurance.

Key Features:

  • Incorporates chemical dosing pumps (plunger or diaphragm type, API 675 compliant).
  • Flow rates typically from 0.1 to 500 LPH, with adjustable metering.
  • Pressure rating up to 15,000 psi, suitable for high-pressure injection lines.
  • Includes chemical storage tank (SS or FRP) with level gauges and drains.
  • Equipped with pressure relief valves, backpressure valves, and check valves.
  • Integrated flow meters, pressure gauges, and sample points for monitoring.
  • Material options: 316SS, Duplex, or Inconel, NACE MR0175 compliant.
  • Skid-mounted, pre-piped, and pre-wired for plug-and-play installation.
  • Manual, pneumatic, or PLC-based control systems for precise regulation.
  • Optional secondary containment and spill trays for environmental protection.

Applications:

  • Corrosion inhibitor, demulsifier, scale inhibitor, and methanol injection.
  • Used in production facilities, pipelines, and subsea injection systems.
  • Supports EOR (Enhanced Oil Recovery) and flow assurance operations.

HIGH PRESSURE TESTING UNITS

Purpose:
Designed to generate and control high pressure for testing critical well control and production equipment such as BOPs, choke manifolds, and valves in the field.

Key Features:

  • Dual-pump configuration for low-pressure fill and high-pressure test modes.
  • Pressure capability up to 30,000 psi (depending on pump type).
  • Utilizes air-driven, diesel, or electric pumps.
  • Constructed as a compact skid or containerized unit for easy transport.
  • Equipped with precision gauges, pressure transducers, and recording instruments.
  • Provides hydraulic or manual control for pressure buildup and bleed-off.
  • Integrated pressure relief and check valves for safe operation.
  • Compatible with water, hydraulic oil, or glycol as test medium.
  • Includes hose reels, quick-connect couplings, and safety barriers.
  • Complies with API 16C, ASME BPVC, and other relevant standards.

Applications:

  • Hydrostatic testing of well control and flow control equipment.
  • BOP stack, choke manifold, and Xmas tree pressure testing.
  • Pipeline and vessel commissioning during installation or maintenance.
  • Used by service companies, testing contractors, and rig operators.

TEST MANIFOLD

Purpose:
Controls, directs, and measures the flow of produced fluids during well testing, cleanup, or production operations.

Key Features:

  • Designed for high-pressure service (typically 5,000–15,000 psi).
  • Fitted with gate valves and choke valves (fixed and adjustable types).
  • Provides multiple flow paths — test line, production line, and bypass line.
  • Equipped with pressure and temperature gauges, sampling points, and flow indicators.
  • Constructed from high-strength alloy steel, NACE-compliant for sour service.
  • Flanged, hub, or hammer union end connections per API 6A standards.
  • Heavy-duty skid-mounted frame for mobility and field use.
  • Optional hydraulic actuation for remote valve operation.
  • Fully hydrotested and function tested before deployment.
  • Designed for safe isolation and controlled flow regulation.

Applications:

  • Used during well testing and flowback operations.
  • Regulates and diverts flow to test separators, burners, or tanks.
  • Monitors pressure, temperature, and flow rate of produced fluids.
  • Essential for production evaluation and well performance analysis.
