Development of high pressure critical hydrogen valve

Recently, PERFECT factory produced a small batch of high-pressure hydrogenation valves. High-pressure hydrogenation is an important process in petroleum deep processing and coal chemical industry. It can not only improve the recovery rate of crude oil but also improve the quality of fuel oil. The dielectric environment of a high-pressure hydrogenation device is characterized by high pressure and hydrogen (with hydrogen sulfide), with flammable and explosive high-pressure gases (hydrogen or hydrocarbon + hydrogen) which store large pressure energy. Once its storage and transportation equipment (including pipeline valves) damage will cause a catastrophic safety accident.

Hydrogen can cause a number of different adverse effects in metallic materials. It can penetrate into the metal material and cause material embrittlement and deformation at normal temperature. Hydrogen sulfide corrosion of metal materials is a very difficult problem, it can cause stress corrosion cracking of metal materials at room temperature and high temperature. All these features have required a strict need for material, structural design and strength design of high-pressure hydrogenation valve. Therefore, the high-pressure hydrogenation valve must face the problems of hydrogen embrittlement and hydrogen corrosion and must pay attention to the problem of leakage under high-temperature and high-pressure conditions. Valves with high-pressure hydrogenation, generally including ball valves, gate valves, globe valves, check valves and plug valves, ASME CL900~2500, room temperature to 400℃.

Valves used in industrial hydrogen applications like petrochemical processes are often made of Cr-Mo steel and Inconel alloy. The main materials of high-pressure hydrogenation valve are A182 F11/F22/F321, A216 WCB, A217 WC6 / WC9, A351 CF8C, Inconel 725 with a diameter DN15-400 mm.

The design and manufacture of hydrogenation valves shall conform to API 600, API 602, BS 1868, BS 1873, ASME B16.34, NACE MR0175, NACE MR0103 and this standard. Our manufacturing center has the ability to produce high-pressure hydrotreating valves and has been successfully applied in hydrotreating equipment (operating pressure 8~10 MPa).

New products: Intelligent voice-activated valve

There are too many types of valve in industrial fields. Intelligent valve transmission command information through digital communication and network, such as valve opening, operation times, operation speed, output torque and other valves. It can remotely set the valve opening range, change valve characteristics, adjust blind area and remote adjustment.

The PERFECT factory has developed a unique intelligent voice-controlled valve. The in-ear earphone has the ability to sense the environment and can connect the external cavity of the earphone with the internal cavity. Most products on the market receive external sound through the electrical signal of the microphone, which will increase the power consumption, while the first miniature acoustic control valve will not. Due to the fact that the micro-acoustic electronic valve is a physical channel, the ambient sound received by it has not been processed twice. Compared with the electrical signal of the microphone, it sounds more natural without delay and distortion.

Over the past years, PERFECT has cooperated with many research and development institutions to make every product in good faith. With our unique technical advantages and rich production experience, coupled with strict product testing, our company has always been committed to providing innovative solutions to optimize the user experience.
