HIGH DEMAND APPLICATIONSHIGH PERFORMANCE SANITARY PROTECTION
Since 1965, Continental Disc Corporation has consistently led the industry in the design and manufacture of innovative, high-quality bursting disc (rupture disc) devices employed in a range of process industries worldwide. These applications include chemical, petrochemical, and petroleum refining, pharmaceutical, beverage, food and dairy, aerospace and electronics industries. CDC maintains an ongoing commitment to providing the products, services, and quality, which customers have come to expect from the leader in over-pressure safety devices. An autoclave is another example of a crucial tool that greatly benefits from the high quality, and durable bursting discs (rupture discs) engineered and manufactured by CDC.
Autoclaves are steam sterilising chambers designed to maintain a sterile atmosphere, contain and withstand extreme conditions of positive pressure, vacuum, heat and moisture. They play an essential role in a wide range of laboratory and industrial applications, specifically the sterilisation of surgical tools, medical equipment and process media.
Consequently, when autoclaves fail to function properly, the resulting down time leads to extremely expensive and time-consuming inefficiencies. Proper mechanical upkeep of autoclave technologies thus represents a major necessity in developing and maintaining efficient, cost-effective operations. A common source of autoclave malfunction is bursting disc (rupture disc) leakage or premature burst due to fatigue. CDC offers a solution to this problem with the SANITRX HPX bursting disc (rupture disc).
Most autoclaves require bursting discs specified to protect the sanitary chamber against system over-pressure. The bursting discs which are not specifically designed to withstand the frequent pressure to vacuum cycles required in these demanding applications can leak or burst prematurely. CDC’s SANITRX HPX Bursting disc (rupture disc) have proven to be durable enough to meet this critical industry need.
CDC’s technical team recently created a solution for a process engineer at a biotechnology facility who was experiencing costly shutdowns. These shutdowns were found to be due to leakage in the bursting discs (rupture discs) used in the autoclave sterilisation equipment at the facility. The CDC team determined that the root cause of this failure was the facility’s utilisation of bursting disc (rupture disc) technology that was developed over 20 years ago and thus no longer the leading technology for the extreme cycle conditions of the autoclave. The result was a fatigued bursting disc (rupture disc) that failed prematurely. CDC solved the problem by replacing all outdated bursting discs (rupture discs) with SANITRX HPX. Built on years of research and development, the HPX Bursting disc (rupture disc) Product Family has proven to withstand over 5,000,000 cycles from full vacuum to 95% of the marked burst rating. Performance at this level represents greater than a five-fold increase over previous industry standards. This extreme durability makes the SANITRX HPX the perfect solution for autoclave pressure protection.
CDC engineers, manufactures and tests each lot of SANITRX HPX bursting discs (rupture discs) to match the precise specifications required to provide the essential over-pressure protection for the equipment and withstand the operating conditions inherent in normal day-to-day autoclave operations. SANITRX HPX bursting discs (rupture disc) incorporate the latest technology features to optimise material thickness, score depth and dome configuration to insure the high performance, flow capacity and durability demanded by today’s process industries. In addition, all SANITRX HPX bursting discs (rupture discs) are designed and manufactured to meet critical ASME BPE criteria including dimensional characteristics required for use in industry standard tubing connections, SF1 or better surface finish, full trace-ability of all materials of construction and FDA/USP Class VI gasket material compliance.
For monitoring burst discs due to an over pressure event, CDC’s BDI or BDI-Flex burst disc indicators are frequently used as part of the SANITRX HPX bursting discs (rupture discs) to automate activation of the over pressure alarm functions in the autoclave control system.
Assentech- Geodesic Dome Installation
Assentech were subcontracted to assemble and install a 25m geodesic dome for Shaft G on the Lee Tunnel project. My experience with Assentech from pre-contract through to assembly has been very positive. Unlike other subcontractors I have experienced on this project, Assentech had a very positive attitude to producing the level of documentation required for a project of this scale. Leading to a high quality pre construction packaged approved in a timely manner. The communication regarding the manufacturing process was first class allowing us to easily plan our works and prepare the site. Dome assembly was carried out very efficiently and completed to programme. The task was correctly resourced and well supervised. The work force had a positive attitude and carried out the task safely. In summary from my perspective it has been a very easy subcontract to manage with a high quality finished product.
We were extremely pleased with the level of service and professionalism demonstrated by Assentech, right from our initial enquiry, through delivery and post installation. As a recipient of only two of these awards made by Eastman Chemical Company in the UK, based on performance in 2014, Assentech are rightly proud of their achievements.
As you said “you delivered what it said on the tin”. On time and on budget. Your up front engineering to determine the suitability of your product for our application was second to none, i have not seen anyone else in the industry pay as much attention to detail before you get the purchase order number as Assentech.
Assentech have supported our Navigator Terminal (formerly known as Vopak Teesside) on two important ~
projects by providing technical assistance and supplying and fitting a total of 11 Internal floating roofs. Both projects have been completed on schedule and on budget. Assentech have provided an excellent level of experience and front end engineering support with high quality drawings and documentation. Their specialist on site labour have worked collaboratively with us and Assentech have proven to be open, honest and flexible partners.
We have experience of both their Heavy Duty Pontoon type and Full Contact IFR’s and we continually monitor operation and performance of all lFR units Installed on site and consider the Assentech supplied Matrix brand to be the best in the market with exceptional build quality and rigidity. Our clients have inspected the installations and have always remarked upon the build quality and have been impressed with their strength in fully supporting up to four people without noticeable deformation. The design and construction of their stainless steel shoe seals continue to prove to operate excellently with no noticeable reduction in performance or flotation ability over the time since Installation.
Assentsch have proven to be extremely competitive on price and their installation and inspection activities have always been thorough. Navigator therefore have no hesitation in recommending Assentech to other companies considering their services.
