Tender Summary

Objectives

The primary objective of this tender is to procure control valves for the Oil Waste Plasma Gasification Project, specifically for the Gas Supply System. The supply aims to ensure reliable regulation and control of oxygen pressure within the plasma gasification process, supporting the safe and efficient operation of the contaminated waste oil plasma gasification facility.

Scope

The scope of the tender includes:

  • Supply of control valves (specifically pressure regulators) suitable for oxygen gas regulation in the plasma gasification system.
  • Provision of valves compliant with specified mechanical and process requirements, including materials, pressure ratings, and connection types.
  • Supply of associated pressure indicators and necessary instrumentation for inlet and outlet pressure monitoring.
  • Ensuring valves meet specified safety, quality, and operational standards as detailed in the technical specifications.

Technical Requirements

The technical specifications for the control valves include:

  • Valve type: Pressure regulator (PCV1602D) for oxygen gas supply.
  • Measurement range: 0 - 1500 kPa(g) (upstream and downstream).
  • Inlet pressure: Minimum 400 kPa(g), normal 600 kPa(g), maximum 1000 kPa(g).
  • Outlet pressure: Setpoint at 400 kPa(g), with a maximum differential pressure of 600 kPa.
  • Flow capacity: Up to 42.93 kg/h.
  • Materials of construction: Body, bellows, spring, seat, disk, and stem made from stainless steel (304/304L SS), with anti-extrusion rings.
  • Connections: Flanged (Class 1500) and NPT threaded connections per ASME standards.
  • Pressure ratings: Valve rated at Class 1500, with maximum shut-off differential pressure of 1000 kPa.
  • Additional features: Local pressure indicators, display capability, and alarm/switch interlocks as specified.

Skills Requirements

The successful bidder should possess:

  • Expertise in the supply and installation of high-pressure control valves, particularly for oxygen service in plasma gasification systems.
  • Proficiency in materials selection and valve design to meet chemical and thermal conditions specified.
  • Capability to provide valves with appropriate mechanical and process connection fittings, including flange and threaded options.
  • Experience in integrating instrumentation such as pressure indicators, alarms, and switches for process safety and control.
  • Knowledge of relevant standards and safety classifications applicable to high-pressure oxygen systems.
  • Ability to supply documentation, drawings, and certifications demonstrating compliance with technical and safety standards.

Joint Ventures, Consortia and Subcontracting:

Most large tenders are composed of tasks in a number of different fields, and it is not always possible for a single company to cater for all of them, and therefore Joint Ventures and Consortia are formed to then submit a tender together.

Government tenders are also requiring the subcontracting of a percentage of the tender work, and the trouble is then finding Subcontractors to comply with the tender requirements

To assist companies with finding tender partners and subcontractors, you can now submit your contact details and company information on this page, so other interested parties can contact you for purposes of forming Joint Ventures and subcontracting
