The plastic-lined elbow is a composite of a carbon steel or malleable iron outer layer and a plastic inner lining, combining the strength of metal with the corrosion resistance of plastic. The lining material can be selected from PE (for clean water), PP (for high temperature), PO (for strong corrosion), and PTFE (for ultra-strong corrosion), meeting the needs of different media. The product is widely used in pipeline systems such as tap water purification, environmental protection sewage, chemical acid and alkali, electroplating acid pickling, pharmaceutical clean, desulfurization and denitrification, HVAC water supply and drainage, and is an economical pipe fitting for low-pressure anti-corrosion, water quality preservation, and scale prevention. We provide all sizes, support non-standard customization, and can confirm specific configurations according to project requirements.

| Outer Material | Carbon Steel / Malleable Iron |
A plastic-lined elbow is a steel-plastic composite anti-corrosion pipe fitting. The outer layer is made of carbon steel or malleable iron to ensure mechanical strength; the inner lining uses PE, PP, PO, or PTFE plastic to provide excellent corrosion resistance and cleanliness. The product is suitable for pipeline systems such as tap water, environmental wastewater, chemical, electroplating, and pharmaceutical applications, effectively preventing rust and scaling while ensuring medium purity. We offer multiple specifications and support non-standard customization to meet different engineering needs.
The steel-plastic composite structure combines metal strength with plastic corrosion resistance, providing a long service life. A variety of lining materials are available—PE, PP, PO, or PTFE can be selected according to medium temperature and corrosiveness to achieve graded corrosion protection. Compared with stainless steel pipe fittings, plastic-lined elbows offer high cost-effectiveness and are an economical choice for civil and industrial anti-corrosion pipelines. In addition, we support low minimum order quantities, regular specifications are in ample stock, and we provide full-dimension customization services.
Plastic-lined elbows are widely used in pipeline systems for tap water purification, environmental wastewater, chemical acid and alkali, electroplating and pickling, pharmaceutical clean processes, desulfurization and denitrification, and HVAC, water supply and drainage. They are particularly suitable for low-pressure, moderately corrosive environments, effectively ensuring water quality and preventing scaling. For ultra-high parameter or strongly corrosive conditions, we recommend upgrading the material; please contact us to confirm specific requirements.
The product comes in a variety of specifications, with regular sizes available from stock. For specific parameters such as diameter, wall thickness, and lining thickness, please contact us to confirm based on project requirements. We support non-standard customization and can provide customization services for dimensions, lining materials, and port/end processes.
We offer flexible purchasing options: small items ship from as few as 1 piece, regular specifications are in ample stock, and large-diameter and special PTFE anti-corrosion products are produced on demand in bulk. We support project material replenishment, sample orders, and consolidated foreign trade shipments. In terms of delivery, in-stock items ship immediately, regular items are delivered within one week, and large-diameter and special anti-corrosion products are scheduled for steady production, capable of supporting urgent engineering orders and on-time export container loading. For specific delivery times, please contact us to confirm.
We provide a 12-month process warranty and lifelong guidance on anti-corrosion material selection. After-sales response is fast, ensuring long-term stable operation of the pipeline system. If you have any questions regarding selection or customization, please feel free to contact us at any time.
We offer four types of lining materials: PE, PP, PO, and PTFE (tetrafluoro). PE is suitable for clean water, PP for high-temperature media, PO for highly corrosive environments, and PTFE (tetrafluoro) for ultra-high corrosion conditions. For specific selection, please contact us to confirm based on your medium and temperature.
