The Unsinkable Navy Ship: The Origin of the Subsafe Program and its Impact on Civilian Ships Today

Navy ship CPV Manufacturing’s products meet government standards and can be found in many areas of the vessels of the US Navy. These high-quality valves and fittings are used on the heavy-duty winches, the anchor windlass of the shops, the Freon-based refrigerator and air-conditioning systems, and the elevator systems that lift aircrafts to the flight deck and in the arresting gear that catch the aircraft.

The US Navy can’t afford to rely on a product that will fail, that’s why they’ve turned to CPV since the 1950s. CPV’s Quality Management System is certified in the areas of Design, Material, Fabrication and Testing and has been approved to meet the requirement of MIL-I-45208, SUBSAFE Level 1, EB 2678. The SUBSAFE Program was put in place after a tragic incident occurred and the USS Thresher was lost at sea in 1963.

Disappearance of Thresher

First launched in 1960, Thresher was the first ship of her class and US submarine technology with nuclear power and a modern hull design. During a deep test dive approximately 200 miles off the northeastern coast of the United State on April 10^th, Thresher was lost at sea with 112 naval personnel and 17 civilians on board.

The immediate cause was unknown, so the Navy restricted all submarined until they could determine the reason behind the loss of the Thresher.

The Thresher Design Appraisal Board reviewed the Thresher’s design and provided recommendations for improvements. The exact cause of the vessel’s loss is unknown, however, it was found that there were deficient specifications, ship building practices, maintenance practices and operational procedures.

Members of the navy attribute the disappearance of the Thresher to the following:

Thresher had 3,000 silver-brazed piping joints that were exposed to full submergence pressure. After testing these joints, results showed that fourteen percent of the joints were substandard. This indicates that possibly more than 400 joints were substandard and could have failed, resulting in the flooding of the engine room.
The crew could not access necessary equipment to stop the flooding.
There was saltwater spray on electrical components that caused short circuits, reactor shutdown as well as loss of propulsion power.
The tank blow system did not operate properly and the submarine couldn’t overcome the weight of water in the engine room.

Birth of the Subsafe Program

Nearly two months after the loss of Thresher, the Subsafe Program was created and has shown a lot of success. Between 1915 and 1963, sixteen submarines were lost in non-combat causes. Since the Subsafe Program, only one submarine has been lost.

The US Navy relies on CPV Manufacturing products to deliver high quality products to keep their vessels running smoothly, and these standards far surpass commercial requirements. All CPV products are delivered to customers meeting all standards of performance, reliability and quality.

The Secret to Long Lasting Valves and Fittings

Customers in need of high-quality valves and fittings are looking for products that are reliable, sustainable, and long lasting. There are specifications that companies must meet, so they’re counting on quality materials that perform well and are safe.

CPV Manufacturing offers the most sustainable products in the market. Find out more about the benefits of these products.

Interchangeability and Durability

Valves and Fittings The original CPV valves were designed in the 1950s and have evolved over time. Since its “original” design, CPV has continued to update and improve on its original design as materials have improved, manufacturing and best practices have evolved. However, every CPV valve manufactured today is backward compatible and interchangeable with similar CPV valves installed in the past. Their long-lasting success is proof of this as CPV products have been in the market for 30-50 years. When your product begins to wear, you can just replace the valve rather than having to replace the entire part.

CPV products don’t fail or wear out. So you’ll rarely need to replace them or have them repaired. In the case that your products do need to be repaired, CPV can service them. Repairs would be determined by the engineering team affiliated with CPV, while CPV provide the valves for specific manufacturers.

These valves and fittings increase the lifecycle and provide the ability to change out the individual part. So, the lifecycle costs are much lower. These long-lasting products are crucial for shipbuilding, since the life of navy ship is between thirty and fifty years.

Reigning over Competitors

When people are using competitors’ products, they aren’t having the same success with their valves and fittings as CPV customers. There is a significant difference between CPV valves and fittings and competitors valves and fittings. Competitors could have issues with their valves in just a year, causing the customer to need to continually purchase more. This means customers are spending a fortune purchasing more products, but they’re also spending their money on products that they are only sure will fail quickly.

While there’s a significant difference between the quality of CPV products and competitors’ products, there’s also a significant different in price. CPV may cost more, but it delivers longevity for every project.

Meeting Standards

CPV Manufacturing serves the following industries: ship building, petrochemicals, and industrial gases. In these industries, valves and fittings must be high-quality and perform efficiently and accurately. A faulty product could result in disastrous damage, that’s why companies in these industries rely on CPV for their non-failing valves and fittings.

The US Navy counts on CPV to equip their vessels with valves and fittings that meet government standards. CPV Manufacturing’s Quality Management System is certified in the areas of Design, Material, Fabrication and Testing and has been approved to meet the requirement of MIL-I-45208, SUBSAFE Level 1, EB 2678.

3 Ways the FloMaster Air Operated Valves Have Improved Industrial Gas Manufacturing

In the oil and gas industries, the products must operate as they were designed to in order to minimize risks that could end up in injuries and damage.

CPV Manufacturing’s FloMaster Air-Operated Valves, are used in conjunction with automated PLC controls in industrial gas-filling facilities. These facilities are increasing their efficiency, profit and accuracy, even for complex, specialty gas mixtures that are filling and mixing by weight gravimetrically. Find out more about the FloMaster Air-Operated Valves and learn how you can benefit from them.

Automated Valves

Air Operated Valves While most valve systems require the man power of a human to manually open and close the valves, FloMaster Air-Operated valves are automated valves. Human controls created an inconsistency in the filling of compressed gas mixtures, causing fills to be rejected. As part of an automated filling system using PLC’s and customized software which controls when to open and close the valves, maximizing operator efficiency and consistent fills minimizing the chance of mistake and human error.

Air Actuation

The FloMaster Air-Operated Valves utilize the pneumatic valve actuator with proven positive shutoff technology. This provided a more accurate way for industrial gas distributors and producers to control their cylinder filling and mixing operations. The air-actuated valves are used with the O-Seal System leakproof valves and fittings for optimum safety and efficiency.

Precision Mixing

Because of the automated valves used in conjunction with automated cylinder filling equipment, the FloMaster provides the ability to fill a precise mixture of gas based on predetermined programmed recipes so you can be certain you’re getting the right mixture every time.

Today, CPV is known around the world for not only the FloMaster air operated shutoff valves, but also the O-Seal Leak-proof System of high pressure valves and fittings, the Mark VIII system or tube size valves and fittings, and the new G-Series stainless steel shutoff, needle and check valves.
