Pipe pliers are designed specifically for clamping and rotating steel pipe workpieces. This tool can be classified into numerous types based on its load-bearing capacity, weight, and unique style. In the field of oil pipeline and civil pipeline installation, pipe clamps play an indispensable role and are widely used.
The working principle of pipe pliers lies in the taper design of their jaws, which can effectively increase torque. The taper is usually controlled within the range of 3-8 degrees, ensuring a firm grip on the tubular object. Pipe pliers can automatically adapt to different pipe diameters and also adapt to plastic deformation caused by the stress applied to the pipe by the jaws. Even with a reduced diameter, it can maintain stable torque and avoid slipping. In addition, a detailed specification table for pipe clamps is provided, including basic dimensions, deviations, and maximum clamping diameter (MM) information.
6 “corresponds to 150MM, with a deviation controlled within ± 3%;
8 “corresponds to 200MM, and the deviation is also controlled within ± 3%;
10 “corresponds to 250MM, with a deviation allowance of ± 3%;
12 “corresponds to 300MM, with a slightly larger deviation of ± 4%;
40 “corresponds to 350MM, with a deviation of ± 4%;
50 “corresponds to 450MM, with a deviation of ± 4%;
60 “corresponds to 600MM, with a deviation of ± 5%;
75 “corresponds to 900MM, with a deviation of ± 5%;
85 “corresponds to 1200MM, with a deviation of ± 5%.
The above specifications are for reference only, and there may be differences in actual products.
- Classification of pipe clamps:
Next, we will explore the detailed classification of pipe clamps. According to different usage scenarios and requirements, pipe clamps can be divided into various types. These types not only differ in size, but also have their own characteristics in terms of functionality and applicability. By understanding these classifications, users can more clearly choose the pipe pliers that are suitable for themselves to meet specific job requirements. - Classification of Pipe Pliers:
According to their load-bearing capacity, pipe clamps can be divided into two levels: heavy grade and ordinary grade. - Weight classification of pipe pliers:
Pipe pliers are divided into heavy-duty, heavy-duty, and light-duty according to their weight to meet different operational requirements. - Differences in styles of pipe pliers:
There are various styles of pipe pliers, including British, American, German, etc., each with its unique characteristics and applicable scenarios. - Material of the handle of the pipe clamp:
The handle material of pipe pliers also varies, such as aluminum alloy, cast steel, etc. Users can choose the appropriate material according to their personal needs and working environment. - Precautions for using pipe pliers:
(1) When using pipe pliers, make sure to choose the appropriate specifications to ensure that they can effectively grip the workpiece.
(2) The opening size of the clamp head should match the diameter of the workpiece to prevent it from sliding or being damaged during the clamping process.
(3) When pulling the pipe clamp, make sure that the clamp head is firmly gripping the workpiece to avoid injury caused by slipping.
(4) If using a force lever, attention should be paid to controlling the length and torque to avoid overloading damage caused by excessive force.
(5) Keep the pliers teeth and adjustment ring clean to ensure their good clamping effect and durability.
(6) Do not use pipe pliers as hammer heads to prevent damage to their structure or unnecessary injury.
(7) Avoid clamping workpieces with temperatures exceeding 300 ℃ to ensure the safety and durability of the pliers.
