Product Overview
KHB-YJZQ Series Welded Pipe Nut is a core connecting accessory specially designed for high-pressure valves and pipeline systems. Manufactured from high-quality carbon steel or stainless steel, the product supports two connection methods: Butt Welding (BW) and Socket Welding (SW), ensuring a permanent and reliable sealed connection between the valve and the pipeline. It is suitable for high-pressure, high-vibration and harsh working conditions.

Application Scenarios
Selection Guide
1. According to the Valve Model: Provide the specific valve model to match the corresponding pipe nut
2. Select Material by Medium: Stainless Steel (304/316L) is a must for corrosive environments
3. Select Welding Method by Working Condition: Butt Welding: For ultra-high pressure, large-diameter pipelines, requiring smooth flow channels
4. Socket Welding: For general high-pressure systems, with convenient installation
Core Advantages
| Advantage | Description |
| High-Strength Connection | Precise matching with valve interface, pressure-bearing capacity up to 31.5MPa and above |
| Dual Welding Processes | Butt Welding (smooth flow channel) / Socket Welding (easy installation), adapting to different needs |
| Flexible Material Options | Carbon Steel (economical and durable), 304/316L Stainless Steel (corrosion-resistant) |
| Zero Leakage Guarantee | Precision-machined sealing cone surface, forming a metal hard seal |

Flow Valve Types: The Short Answer First There are nine flow valve types used across piping systems today: gate, globe, ball, butterfly, check, plug, needle, diaphragm, and pinch valves. Each one controls flow through a different mechanical action — a wedge that drops into place, a disc that rotates ninety degrees, a ...
View MoreVacuum Valve Basics: What They Do and Why the Right Choice Matters A vacuum valve is a mechanical component that isolates, throttles, or directs gas flow inside a system operating below atmospheric pressure. Unlike standard process valves, a vacuum valve must seal against pressure differentials acting inward rather th...
View MoreActuated Gate Valves Explained: Direct Answer First An actuated gate valve is a standard gate valve fitted with an electric, pneumatic, or hydraulic actuator that opens and closes the gate automatically instead of relying on a handwheel. The actuator replaces manual torque with motor-driven, air-driven, or fluid-drive...
