Definition and Structure
U type Wire, also known as U-bolt or U-pipe clamp, is a long metal product with a U-shaped cross-section. Its two ends usually have threads that can be combined with nuts to secure tubular objects (such as water pipes) or sheet-like objects (such as car leaf springs). Due to its fixed object like a person riding on a horse, it is also known as a saddle bolt.
Materials and Classification
Material:
Carbon steel, such as Q235A, Q345B, etc., has high strength and toughness and is suitable for general industrial environments.
Alloy steel: By adding alloying elements, the strength and corrosion resistance of the material are improved, making it suitable for applications with high performance requirements.
Stainless steel, such as 201, 304, 316, etc., has excellent corrosion resistance and high temperature resistance, and is suitable for corrosive environments such as chemical, pharmaceutical, and environmental protection. Stainless steel U type Wire can be divided into different types such as cold rolling, hot rolling, and precision rolling according to production processes and performance requirements.Classification:
According to shape, it can be divided into semicircles, squares, right angles, triangles, oblique triangles, etc.
According to usage, it can be divided into U type Wire for construction, U type Wire for machinery, U type Wire for vehicles, etc.Specifications and standards
Specifications:
The main production specifications of U type Wire cover M6 to M64 (diameter), and the length is customized according to user needs, generally ranging from 250mm to 600mm, and can also be longer.
Some U-shaped wire products also offer diameter specifications in inches, such as 1/4 "to 2-1/2".Standard:
The production of U type Wire follows national standards (such as GB) or industry standards (such as JB/ZQ4321-1997), and can also comply with German standards (DIN3570) or other international standards according to customer needs.
There are various product grades available, which can perform performance levels such as 4.6, 5.6, 6.8, 8.8, 10.9, 12.9, or international standards such as SAE J429, ASTM A307, ASTM A325, ASTM A490, etc.Production process
The production process of U type Wire mainly includes steelmaking, hot rolling, cold rolling, drawing, and heat treatment
Steelmaking: By adding alloying elements, the strength and corrosion resistance of stainless steel are ensured.
Hot rolling: Heating steel billets to a certain temperature and rolling them into steel plates of a certain thickness.
Cold rolling: Rolling steel plates into thinner and more precisely sized sheets at room temperature.
Pulling: The sheet metal is drawn into a U-shaped wire by a drawing machine, which requires precise control of the drawing force to avoid excessive deformation or fracture.
Heat treatment: After cold rolling and drawing, U type Wire usually needs to undergo solution treatment, aging treatment, or annealing treatment to improve its strength and toughness.
