Darchem Nuclear Systems
Darchem Engineering has held a prominent position in the design, manufacture and installation of thermal insulation systems for nuclear steam raising plant for almost fifty years.
Involvement with the nuclear industry has been extended over that period into passive fire protection systems and major fabrications such as pool liners.
Backed by the parent company Esterline Corporation, investment and continuous product development, Darchem has all the attributes to provide the highest service to the Nuclear Industry.
Encapsulated Thermal Insulation
Darchem Engineering have an enviable reputation in the supply of thermal insulation systems to nuclear power plant since the earliest Magnox Stations in the UK which has now extended worldwide to over 160 reactors.
With a commanding expertise in the design; comprehensive testing of actual systems rather than single panels; an understanding, borne from expertise, of installation and a manufacturing facility using modern methodologies, Darchem offers its customers a "turn key" service.
Over 40 years continuous experience in metallic reflective insulation applications to nuclear power plant.
The Darchem system for fabricating pool liners ensures that they will be leak proof for their complete life.
The pool liners methodology for assembly has been achieved by close co-operation between Darchem design and manufacturing engineers so that there is a modular approach thereby enabling thorough NDT of all welds and reduced site installation time. This modular approach also allows a high degree of automation.
In addition Darchem can provide fuel storage racks and other pool furniture.
KM1 Cable Protection
The KM1 system of fire protection to cable trays and cables was developed specifically to meet the challenges of fire hazards in nuclear power plant. Available in one hour and three hour standards, KM1 has one of the lowest ampacity derating factors for a fire barrier with an equivalent capability and protection duration.
Extensively supplied and fitted to 29 nuclear power plant in USA and Korea KM1 provides the customer with a reliable system of fire protection.
The Darshield is a robust passive fire protection unit aimed at specific plant items such as valves, actuators and control cabinets where ready access is essential.
The Darshield design has mainly evolved in the petrochemical industry and therefore has a proven reputation to accommodate the most demanding of environments.
High Grade Fabrications, Piping Systems And Specialist Equipment
High Grade Fabrications
With Darchem design and manufacturing engineering expertise Darchem is able to provide equipment to the highest standards. Tightly toleranced and high grade materials are where Darchem core skills are most utilized.
Darchem have a blend of manufacturing and production engineering ability that provides the ideal solution for supply of medium volume waste containers. A manufacturing cell with the appropriate degree of automation ensures a high quality is continually reproduced.
The more complex and demanding pipe systems with some specialist unit operations are sought by Darchem Engineering. With design, manufacture and installation co-ordinated by proficient project management the customer can be assured that the system is right first time and on time.
Honeycomb Crush Pads
Wherever there is the possibility of a dropped load the provision of a stainless steel honeycomb crush pad can prevent damage to the equipment dropped on the floor beneath. The Darchem crush pad gives a guaranteed maximum force to both floor and equipment with precise predictions of energy absorption.
Similarly a crush pad is used in pipe whip restraints to absorb the energy of a pipe break.
