Xintong Cast Pipe (Guangdong) Co., Ltd. presents our comprehensive range of ductile iron tapered fittings – including Double Socket, Socket-Spigot, and Spigot-Socket Tapers. These engineered components are designed to provide smooth diameter transitions, connect different pipe end types, or adapt between various joining methods in municipal water supply, drainage, industrial pipelines, and water conservancy projects. Whether you need to reduce pipe size, change from a socket to a spigot end, or create a flexible junction, our tapers deliver reliable, leak-proof performance.

Precision Engineering & Quality Backbone

Leveraging our advanced centrifugal casting technology and fully automated production lines (100,000 tons annual capacity), each taper is manufactured to meet ISO 2531, EN 545, and GB/T 13295 standards. We begin with high-purity pig iron and conduct strict in-process inspections using spectrometers and hydrostatic testing machines. Every piece undergoes airtightness, pressure resistance, and seismic testing to ensure zero defects. With five invention patents and certified technical processes, our tapers offer exceptional dimensional accuracy, consistent wall thickness, and outstanding corrosion resistance – even under variable pressure and aggressive soil conditions.

Tailored Solutions for B2B Partners (Wholesale / Custom / OEM/ODM)

As an integrated manufacturer combining R&D, production, sales, and service, we specialize in meeting the unique requirements of infrastructure contractors, pipeline distributors, and engineering firms:

• Configuration Flexibility: Choose from Double Socket (socket both ends), Socket-Spigot (one socket + one spigot), or Spigot-Socket Tapers (tapered transition) – available in DN80 to DN2600.

• Custom Dimensions & Angles: We can tailor taper length, reduction ratio, and end configurations to your specific piping layout.

• Special Anti-Corrosion Coatings: Epoxy ceramic, polyurethane, or other treatments as specified – ideal for potable water, wastewater, or high-chemical environments.

• OEM/ODM Services: Your branding, packaging, technical labels, and even custom alloy formulations are fully supported.

• Wholesale & Bulk Orders: Competitive factory-direct pricing, low minimum order quantities, and reliable global logistics (exporting to Southeast Asia, the Middle East, Africa, and beyond).

Why Choose Our Tapered Fittings?

• Seamless Integration: Engineered to connect pipes of different diameters or end types without additional adapters – saving time and reducing potential leak points.

• Full-Cycle Support: 24/7 pre-sales technical consultation, installation guidance, and after-sales maintenance from our dedicated team.

• Sustainable Manufacturing: Produced using waste heat recovery and water recycling processes – a green choice for your supply chain.
