定义
A mechanical fastening system consisting of male and female threaded components that create a secure, pressure-tight joint through helical engagement, designed specifically for well body assembly in industrial machinery where structural integrity and leak prevention are critical.
工作原理
Works through helical thread engagement where rotational force converts to axial clamping force, creating mechanical interference and friction that resists separation while maintaining alignment and sealing integrity under operational loads.
材料
Typically manufactured from alloy steels (AISI 41404340)stainless steels (316L17-4PH)or specialized alloys with hardness ratings of 28-32 HRC minimumoften with corrosion-resistant coatings or platings.
Length
Variable based on application
Thread Type
Metric (M), Unified (UNC/UNF), or API threads
Thread Pitch
Standard or fine pitch based on diameter
Diameter Range
M6 to M64 (or equivalent)
Surface Finish
Ra 1.6-3.2 μm
Pressure Rating
Up to 10,000 psi (690 bar)
Temperature Range
-40°C to 200°C
Thread Engagement
Minimum 1.5 times diameter
Torque Specification
30-500 Nm depending on size and material
标准
ISO 898ISO 965DIN 13DIN 934ASME B1.1API 5CT

常见问题

What are the main advantages of threaded connections in well body assembly?

Threaded connections provide reliable pressure sealing, easy assembly/disassembly for maintenance, excellent load distribution, and vibration resistance while maintaining precise alignment of components.

How do you prevent thread galling in stainless steel connections?

Use anti-galling compounds, ensure proper lubrication, control assembly speed, maintain clean threads, and consider using dissimilar metals or specialized coatings to reduce friction and material transfer.

What torque control methods ensure proper threaded connection installation?

Methods include torque-only, torque-turn, yield control, and ultrasonic measurement, with selection based on criticality, material properties, and required preload accuracy.
