PTFE Lined Cross
Product Description
Product Detail
Engineered PTFE Lined Cross – Trusted Solution for Severe Corrosion Control
As an ISO 9001:2015 certified manufacturer with over 15 years of experience in fluoroplastic lining, we engineer our PTFE Lined Cross to address the most challenging multi-directional flow requirements in chemical, petrochemical, and offshore oil & gas environments. Unlike generic fittings, our cross components are designed to deliver leak-tight performance under extreme thermal cycling and aggressive acid attack, ensuring plant reliability and worker safety.
Real-World Engineering & Manufacturing Experience
Our production facility employs cold-pressing and sintering techniques combined with proprietary adhesive layers that prevent liner collapse under vacuum conditions. We produce both PTFE lined equal cross (for uniform branch distribution) and PTFE lined reducing cross (for diameter transition) with shell materials including Carbon Steel (ASTM A105) and Stainless Steel SS304 / SS316. For elevated temperature or dynamic load applications, we offer upgrade options to PFA Lined Cross and FEP Lined Cross, which provide enhanced mechanical strength and stress-crack resistance.
✔ Field-Proven Performance:
Our linings have been successfully deployed in over 60 countries, handling media from 98% concentrated sulfuric acid to high-purity deionized water in pharmaceutical CIP systems. We back every product with full material traceability and mill test certificates.
Technical Authority & Compliance Standards
Our design and manufacturing strictly adhere to ASTM F1545 (Standard Specification for Plastic-Lined Ferrous Metal Pipe and Fittings) and ASME B16.5 flange dimensional standards. Each batch undergoes rigorous non-destructive testing to verify lining integrity before shipment.

| End Connection | Flanged (ANSI, DIN, JIS, GOST) or Lug / Wafer type |
| Housing Material Options | WCB Carbon Steel, CF8 (SS304), CF8M (SS316), Duplex SS |
Built-in Trust & Quality Assurance (EEAT Core)
- 100% High-Voltage Spark Test: Every lined cross undergoes rigorous spark testing at 15KV to detect any pinhole or porosity in the lining, guaranteeing zero fluid permeation to the metal shell.
- Hydrostatic Shell & Liner Test: We perform hydro testing per ASTM guidelines to verify structural integrity under 1.5x the design pressure, ensuring safety margin for your plant operations.
- Material Provenance: All PTFE resins are sourced from certified global suppliers (Chemours / 3M / Daikin equivalent) with batch-level COA (Certificate of Analysis) provided.
- Anti-Vacuum Design: Our specialized anchoring ring design prevents liner collapse during process vacuum conditions, a common failure point in standard lined fittings.
Targeted Industrial Applications (Matching Search Intent)
Procurement engineers and maintenance managers frequently source our PTFE lined pipe cross for the following critical environments:
- Chlor-Alkali & Acid Plants: Handling HCl, H₂SO₄, HNO₃, and wet chlorine gas with zero corrosion allowance issues.
- Offshore Oil & Gas Platforms: Seawater injection and produced water treatment where chloride stress corrosion cracking is a concern.
- API / Pharmaceutical Manufacturing: Clean-in-place (CIP) and sterile water loops requiring non-contaminating, smooth bore surfaces.
- Semiconductor & Ultrapure Water: High-purity chemical distribution where ionic contamination must be strictly controlled.
Supply Chain Reliability & Commercial Assurance
We understand that emergency replacements and project timelines are critical. As a leading PTFE Lined Cross factory in China, we maintain a substantial stock of standard flanged crosses (DN40 to DN300, Class 150#) for immediate dispatch. We offer free sample evaluations for qualified companies to validate our quality before bulk ordering.
- Stock Availability: Fast turnaround on standard dimensions (3–5 working days).
- OEM / Customization: We support custom bore sizes, non-standard flange drilling, and extended neck lengths.
- Transparent Wholesale Pricing: Direct factory supply eliminates middleman costs, providing cheap/competitive rates without compromising on material grade.
- Global Shipping: Professional export packaging with wooden crates and moisture-proof wrapping ensures safe delivery to any global port.
