High-Quality Threaded Screwed Flange with NPT Thread, ASTM A105 Class 150
Product Overview
Cangzhou Hongxin is a leading manufacturer and supplier of premium industrial pipe flanges. Our Threaded Screwed Flange with NPT Thread is manufactured from ASTM A105 carbon steel and rated for Class 150 pressure. Designed for a secure and leak-proof connection, this flange is the ideal solution for low-pressure piping systems where welding is not desired or practical. The key advantage of our product is that it requires no welding, allowing for quick installation, easy maintenance, and disassembly.
Key Features
No Welding Required: The primary benefit of our threaded flange is its simple installation. The NPT threads screw directly onto the pipe, eliminating the need for costly, time-consuming, and certified welding processes. This reduces labor costs and installation time significantly.
Robust Material: Constructed from ASTM A105 carbon steel, this flange offers excellent strength, durability, and performance in a wide range of applications, including steam, water, oil, and gas service.
NPT Thread Standard: The National Pipe Taper (NPT) thread ensures a tight, pressure-tight seal. The tapered design helps to prevent leaks by creating a metal-to-metal seal as the flange is tightened onto the pipe.
ASME B16.5 Class 150 Compliant: Manufactured in accordance with ASME B16.5 standards, our flanges guarantee dimensional accuracy, interoperability, and reliable performance under pressures up to Class 150 rating.
Easy Maintenance & Inspection: Threaded connections allow for straightforward disassembly. This makes our flanges perfect for systems that require frequent inspection, cleaning, or modification.
Cost-Effective Solution: By saving on welding equipment, skilled labor, and inspection costs, our threaded flanges provide a highly economical connection method for non-critical, low-pressure services.

FAQ Section
Q1: Can this threaded flange be used for high-pressure applications?
A: No. Threaded flanges are generally not recommended for high-pressure or high-temperature services, cyclic loading, or highly corrosive environments due to the potential for thread leakage. For such applications, we recommend our Weld Neck or Slip-On flanges.
Q2: How do I ensure a leak-proof seal with an NPT threaded flange?
A: For a secure seal, it is recommended to use a suitable pipe sealant or PTFE tape on the male threads before assembly. This helps to fill any minor imperfections and prevents leakage.
Q3: Does Cangzhou Hongxin provide certifications?
A: Yes. We can provide Mill Test Certificates (MTC) and other compliance documentation upon request, ensuring full traceability and quality assurance.
