Features
- Pioneering in China:Since 2009, HNA has been the first manufacturer in China to design and fabricate polyurethane - bonded valves for American customers. This early - entry advantage showcases HNA's technological prowess and innovation in the valve - manufacturing industry.
- Valve Body Structure and Materials:The valve features a high - pressure forged one - piece integral valve body with a bottom guide (valve leg/wing). It is crafted from AISI 8620(20CrNiMo) or AISI 8620H(20CrNiMoH). Customized materials are also available, catering to diverse engineering requirements.
- Advanced Treatment Processes:World - class heat treatment and carburizing technology are employed. This ensures optimal mechanical properties, including tensile strength, yield strength, Charpy impact strength, elongation, etc., with a surface hardness of 60 - 65 HRC. The temperature and corrosion resistance performance exceed API standards, significantly extending the valve's service life.
- Precision Machining:Utilizing world - top - class precise machining crafts, high - precision components with a close - tolerance fit are produced. This meticulous machining not only enhances the valve's performance but also reduces wear and tear, ensuring long - term reliable operation.
- Exceptional Performance:HNA valves adhere to the API standard for cementing and fracturing media such as sand and man - made resin - coated sand proppants. They deliver unparalleled performance under extreme conditions, like pumping high - strength ceramic proppants or sintered bauxite proppants at pressures over 15,000 psi and pump rates exceeding 1,000 SPM. Multiple elastomers are available for customized applications, meeting the specific needs of different projects.
- Valve Body Design Advantages:Based on an extreme - pressure well - service valve design, the one - piece forged valve body can meet the demands of the most hostile drilling environments globally. The tough integral valve body with a tapered leg guide boosts the structural strength of the valve body due to its high tensile strength, thus extending the operational lifespan. It also increases the flow area, reduces abrasion, and decreases fluid velocity, providing superior strength, longer run - times, and cost - savings.
- Bottom Guide Design:4 - wing, 3 - wing, and custom - designed bottom - guide valve bodies can be paired with full - open valve seats. When pumping abrasive mud liquid, the tapered bottom - guide legs increase the flow area and reduce fluid velocity, creating a smoother flow. This reduces abrasion and extends the valve's service life. The design with tapered bottom - guide legs is more suitable for high - speed pumping. The precisely tapered and balanced design of the bottom guide ensures uniform loading characteristics, guaranteeing better sealing performance.
- Benefits of Bonded Valve Type
- Enhanced Structural Strength:The bonded valve type increases structural strength with very high tensile strength, ensuring a longer operation life. This is crucial for withstanding the harsh conditions in well - service applications.
- Improved Shock Absorption:It improves shock absorption and minimizes shock when the valve closes. This not only protects the valve itself but also reduces the impact on the entire system.
- Superior Sealing Capabilities:By reducing the possibility of fluids penetrating between the polyurethane insert and the valve body, it enhances sealing capabilities and prevents sealing failure.
- High - Performance Polyurethane:The high - performance polyurethane imported from the USA exhibits the following excellent properties:
- Outstanding Extrusion/Abrasion Resistance:It has extremely perfect high extrusion/abrasion resistance, enabling it to withstand the abrasive forces in drilling operations.
- Exceptional Chemical/Corrosion Resistance:The high chemical/corrosion resistance is extremely perfect, making it suitable for use in environments with corrosive substances.
- High Pressure Resistance:It can resist a maximum pressure of 15,000 Psi, ensuring reliable performance under high - pressure conditions.
- Temperature - Rated Polyurethane Options:There are two temperature - rated polyurethane valve inserts available: a regular - temperature 220°F (105°C) (yellow) insert and a high - temperature 300°F (150°C) (white) insert. This allows users to select the most appropriate insert according to the operating temperature of their applications.
- Sealing Design:The precisely tapered design of the insert, which matches the seat, provides evenly distributed loading characteristics, ensuring better sealing performance. Double - angle designs of 55°, 45°, or other specified tapers are available to accommodate different valve types, pump types, and applications.
- Valve Seat Compatibility:The valve is compatible with both API valve seats and non - API modified valve seats. When paired with the HNA valve seat, the large metal - to - metal bearing area on the valve - seat surface enables maximum fluid flow and a longer service life.
- Shelf Life:Under proper storage conditions, the valve has a perfect shelf life of less than 36 months. This ensures that the valve remains in good condition until it is put into use.
- Extra - Long Service Life:The HNA bottom - guide valve body - one - piece forged with bonded polyurethane is the supreme type of valve available today for the toughest well - service environments, boasting an extremely super - long service life. This long - lasting performance makes it a reliable choice for demanding applications.
- Polyurethane Material Options:Customers can choose between domestic high - quality polyurethane and USA high - performance polyurethane. This provides flexibility in meeting different performance requirements and cost - effectiveness considerations.
- Interchangeability:The valve is fully interchangeable with SPM 2.0 Valve and other major bonded valve types. It is available in API 3# through API 9# sizes, as well as non - API modified types and sizes. This interchangeability simplifies maintenance and replacement processes, offering convenience to users.
- Customized Rubber Option:Customized bonded NBR/HNBR rubber is available as an option. This allows for further customization to meet specific application requirements, such as better chemical resistance or enhanced sealing in certain conditions.
