Single-Direction Connection Bushing-40

Product details

Product Introduction
The Single-Direction Connection Bushing-40 is a special connection and protection component made of high-quality epoxy resin via the APG molding process, specially designed for one-way fixed connection and sealing protection of pipelines, conductors and other scenarios. Its integrated molding structure ensures the stability of one-way connection, precisely adapting to the size of DN40 pipelines/conductors. The sealing groove design, combined with special sealing materials, can effectively prevent medium leakage and external impurity intrusion. The inner wall of the bushing is treated with an anti-corrosion coating to enhance rust and corrosion resistance, with standard connection interfaces reserved at the ends, adapting to one-way connection methods such as welding and flanging. It is widely used in water supply and drainage, power, petrochemical and building pipeline systems, providing a reliable, sealed and durable solution for one-way connection of various pipelines and conductors.
Product Overview
Based on high-quality epoxy resin, the Single-Direction Connection Bushing-40 is manufactured by combining precision APG molding and anti-corrosion treatment processes, specially designed for the one-way fixed connection and sealing protection needs of DN40 pipelines and conductors. Through structural optimization and material upgrading, the product achieves multiple improvements in connection stability, sealing reliability and environmental adaptability, with the following core characteristics:
1. Structural Features
- One-way adaptation design: Precisely matching DN40 specification, adopting a one-way integrated structure, focusing on one-way connection and fixation, eliminating connection loosening caused by two-way displacement, and adapting to various one-way force-bearing scenarios.
- Sealing protection structure: Built-in special sealing groove that can be filled with sealing materials, withstanding water pressure of 0.3MPa and above without leakage, effectively isolating medium leakage and external dust and moisture intrusion, and ensuring long-term stable operation of the connection part.
- Integrated connection interface: Standard welding or flanging interfaces are reserved at the ends, which can be directly docked with DN40 pipelines and conductors without additional accessories, simplifying the connection process and ensuring the sealing and conductivity of the connection (in conductor connection scenarios).
- Installation adaptability: Suitable for embedded and exposed installation in construction, industrial and other scenarios, can be directly buried underground without setting maintenance wells, with small installation tolerance. The perpendicularity deviation between the central axis of the bushing and the installation surface is ≤3‰, adapting to various construction environments.
2. Performance Advantages
- High connection strength: High-quality epoxy resin has excellent compression and tensile properties, and the tensile strength of the joint meets relevant standards, which can resist pipeline vibration, medium pressure and external impact, ensuring no loosening or fracture of one-way connection.
- Corrosion resistance and durability: Epoxy resin itself has excellent corrosion resistance, and the inner wall is treated with a special anti-corrosion coating process, with outstanding rust and corrosion resistance, no special requirements for chloride ion content, suitable for corrosive environments such as acid-base media and industrial pollution, with no obvious damage after 3 months of outdoor storage.
- Environmental adaptability:
- Operating in a wide temperature range (-40℃～+120℃), no low-temperature embrittlement or high-temperature deformation, adapting to severe cold and high-temperature working conditions;
- Wear-resistant and anti-aging, can be used for a long time in complex environments such as underground embedding and outdoor exposure, achieving maintenance-free operation for more than 20 years.
3. Typical Application Scenarios
- Building water supply and drainage systems: One-way connection and sealing protection of DN40 water supply and drainage pipelines through walls and buried parts, preventing wall water seepage and dampness, adapting to humid areas such as toilets and kitchens.
- Power system: Protection of one-way connection parts of medium and low voltage conductors, adapting to the fixation and auxiliary insulation protection of DN40 conductors in switchgear and distribution boxes, improving connection reliability.
- Petrochemical field: One-way connection of light chemical pipelines, adapting to transmission pipelines without strong corrosive media, realizing stable connection and sealing protection, complying with industry safety standards.
- Embedded pipeline projects: One-way connection of DN40 pipelines in building and municipal embedded pipelines, adapting to various pipes such as PE pipes, PPR pipes and galvanized steel pipes, simplifying the construction process and reducing project cost.
4. Core Values
- Reliable connection: The one-way integrated structure and standard interface design eliminate connection loosening and medium leakage, reduce the incidence of pipeline and conductor connection failures, and extend the service life of the system.
- Efficient construction: Adapting to multiple installation methods, no additional accessories are needed, and it can be directly docked with DN40 components, reducing construction complexity, improving on-site operation efficiency, and adapting to all-weather construction.
- Compliance with standards: Meets GB/T 700, GB/T 3280 (stainless steel material) and other relevant industry standards, adapting to the compliance requirements of various industrial and construction scenarios, and ensuring the safe operation of the system.
