Swivel Coupler

Swivel Couplers are mainly used to connect and fix two components while allowing flexible rotation, which facilitates construction. Generally, fasteners refer to intermediate connecting parts used to join two components, and in construction projects, they are mostly used to fix scaffolding pipes with an outer diameter of Φ48mm.

Swivel Couplers are used to connect components that are parallel or obliquely intersected. Diagonal braces should be fixed with rotary fasteners on the extended end of the intersecting horizontal pole or on the vertical pole. The distance from the center line of the rotary fastener to the main node should not be greater than 150mm.

Swivel Couplers are favored in construction due to their unique performance and uses. The following is a systematic summary of the casting process of rotary fasteners, as well as their application in scaffolding and anti-corrosion measures.

I. Casting Process of Rotary Fasteners

Swivel Couplers are used to connect parallel or obliquely intersected components, and their casting process mainly includes the following steps:

Raw Material Preparation: The main raw material of rotary fasteners is metal, with commonly used materials including aluminum alloy, stainless steel, carbon steel, etc. In the production line process, raw materials need to be proportioned, screened, and preprocessed to ensure they meet production requirements.

Melting and Casting: After preprocessing, the raw materials enter the melting and casting stage, which includes multiple steps such as melting, pouring, and cooling. During the melting process, the raw materials need to be heated above their melting point to turn them into a liquid state. Then, the liquid metal is poured into the casting mold, and after cooling, it is taken out to form the initial shape of the rotary fastener.

Processing and Shaping: The initial shape after casting is not perfect and needs further processing and shaping. This stage includes steps such as removing surface defects of the casting, cutting, trimming, and grinding. In the process of processing and shaping, various mechanical equipment and tools such as cutting machines and grinders need to be used.

Quality Inspection: Quality inspection is an indispensable part of the casting fastener production line process. The quality of rotary fasteners is evaluated through various testing methods such as non-destructive testing, chemical composition analysis, and physical performance testing. Only those that pass all inspections and meet the standards can be put into use.

II. Application of Rotary Fasteners in Scaffolding

Swivel Couplers are mainly used to connect and fix steel pipes and other components in scaffolding, featuring convenient installation and strong stability. Their applications are as follows:

Connection Function: Swivel Couplers can connect multiple steel pipes to form a stable support system.

Angle Adjustment: Swivel Couplers can rotate, so they can adapt to connection requirements at different angles, making the construction of scaffolding more flexible.

Strong Load-Bearing Capacity: Swivel Couplers are carefully designed and cast, with high load-bearing capacity, which can meet the load-bearing requirements of scaffolding.

III. Anti-Corrosion Measures for Scaffolding

Since scaffolding is mostly exposed to the outdoor environment, it is susceptible to erosion from wind, sun, rain, and snow. Therefore, anti-corrosion measures need to be taken to extend its service life. The specific measures are as follows:

Choosing High-Quality Materials: When building scaffolding, high-quality steel pipes, fasteners, and other materials should be selected to ensure they have good corrosion resistance.

Surface Coating Treatment: The surface of scaffolding steel pipes and fasteners should be coated with anti-rust paint, etc., to improve their corrosion resistance.

Regular Inspection and Maintenance: Regularly inspect and maintain the scaffolding, and promptly detect and deal with corroded and damaged parts to prevent further spread of corrosion.

Timely Replacement of Damaged Components: For severely corroded scaffolding steel pipes and fasteners, they should be replaced in a timely manner to ensure the stability of the overall support frame.

In summary, the casting process of rotary fasteners includes raw material preparation, melting and casting, processing and shaping, and quality inspection. In scaffolding, rotary fasteners have the characteristics of connection, angle adjustment, and strong load-bearing capacity. To extend the service life of scaffolding, it is necessary to take anti-corrosion measures such as choosing high-quality materials, surface coating treatment, regular inspection and maintenance, and timely replacement of damaged components.
