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.
