Pipe clamps are an half ring shape fasteners used to secure cylindrical objects. They are widely used in power transmission, telecommunications, construction, machinery, and petrochemical industries.Their working principle is simple yet effective. By tightening bolts, the metal ring closely grips the object to prevent slipping, shaking, or loosening. In engineering applications, hoop clamps are not only used to secure conductors and cables on poles but also play a key role in supporting cross arms and transferring tension forces.
Various Types and Structural Features of Pipe Clamps
1.Top Pole Support Clamp
It is installed at the top of poles, this type provides support and fixation for equipment. According to installation needs, it can be classified into Single-top single-clamp,Double-top single-clamp,Single-top double-clamp,Double-top double-clamp. These are typically used for 10kV and below line equipment installation.
2. Stay Wire Clamp
This type is mainly used to secure stay wires that stabilize poles in power lines.Especially at branch poles, corner poles, and terminal poles.
According to structural needs, stay wire clamps can be categorized as Flat clamp,Reinforced flat clamp,Double stay wire clamp,Four stay wire clamp.Specifications are usually indicated by the size of the flat steel and the pole diameter. For example, 60×6×150 represents a clamp made from 60mm wide, 6mm thick flat steel, suitable for a 150mm pole diameter.
3.Conductor Clamp
An essential component in power lines, available as conductor clamps and conductor-stay clamps, used to hang or fix conductors and stay wires.In 10kV and below power projects, conductor clamp specifications are typically labeled according to design drawings.
4.Cross Arm Support Clamp & Cross Arm Stay Clamp
Used mainly in 35kV and above power lines to support cross arms or to support both cross arms and stay wires simultaneously.
The cross arm stay clamp includes an additional stay plate compared to the standard type, providing greater stability and load-bearing capacity.
5.Lifting Clamp
Also called “raising clamp,” this type is specifically designed to lift or raise cross arms.
It features double bolt holes on one side of the mounting lug and is typically assembled using four necked bolts for maximum stability.
Specifications are marked by flat steel size and pole diameter — for example, 80×8×280.
6.Cable Clamp
Specially designed for securing cables when ascending or descending poles.Depending on cable quantity, it is available in single, double, or multi-cable versions. Specifications are defined by material and pole diameter — e.g., 60×6×320.
7.Stay Foot Clamp
Used for stay foot installation in 10kV and below line projects.Common types include Welded plate stay foot clamp,Welded bolt stay foot clamp (also known as “goat horn clamp”),Reinforced flat stay foot clamp. Specifications are based on material size and pole diameter, such as 60×6×210.
8.U Bolt Clamp (Round Steel Clamp)
Made from round steel, designed to connect angle steel components with round poles. Each set typically includes 4 nuts and 2 square washers for secure fastening. Specification format: φd×D, where φ is the round steel diameter, d is clamp diameter, and D is the pole diameter. For example, φ16×250 indicates a clamp made from 16mm round steel for a 250mm diameter pole.
Customization
Every construction project has unique designs and installation requirements,standard clamps often cannot fully match field conditions.
That’s where custom pipe clamps offer their real value. At Fastenmetal, we provide piple clamps from stand to industrial heavy pipe clamps:
1.Multiple material options: flat steel, round steel, hot dip galvanized steel, and stainless steel.
2.Drawing-based production: one-on-one customization according to CAD drawings or samples.
3.Precision manufacturing: CNC machining ensures accurate hole positions and dimensions.
4.Strict quality inspection: every batch is tested for size accuracy, coating thickness, and tensile strength.
Whether it’s a standard stay wire clamp for power lines or a complex custom structure for wind power or telecommunication projects,
Fastenmetal manufactures to the highest standards to ensure safety, strength, and long-lasting durability.
