Jack Bolt Type Large-Diameter Pipe Aligner

This product is a mechanical pipe alignment device that utilizes high-strength adjusting bolts (jack bolts). By manually rotating these bolts, it generates powerful radial clamping force to restore pipe end roundness, align pipe sections, and secure the joint interface. Characterized by its simple structure, durability, reliability, and low cost, it achieves precise pipe end shaping, accurate positioning, and stable support. It provides the crucial foundation for obtaining high-quality circumferential weld seams, making it an essential tool for large-scale pipeline engineering projects.

Pipe Chain Clamp

This chain clamp packs a serious punch with the ability to reform pipe up to Schedule 40 and to align pipe up to Schedule 80, yet its lightweight construction also makes it an easy-to-use and easy-to-transport external line up clamp. It can even be used as a single jackscrew clamp. This Chain Clamp can do the job of many bulky cage clamps, saving time and money when needing an adjustable pipe clamp.

Tack Welding Alignment Tool

This product is a specialized tool designed for pipe welding. It assists welders in quickly completing tack welding preparation. It is suitable for precisely aligning and connecting pipe-to-pipe, pipe-to-elbow, and pipe-to-flange joints, ensuring coaxial alignment of the connected pieces. This guarantees roundness, gap consistency, and concentricity of the pipe ends meet welding requirements, preventing misalignment or uneven gaps that can compromise weld quality.

Large Multiples Tube Bender

The Large Multiples Tube Bender is used for bending metal pipes. Its core characteristic is the ability to create bends with a large bending radius, meeting the stringent requirements of specific projects regarding fluid resistance, pipe stress, and spatial layout. In precision industries such as semiconductors and nuclear power, to avoid turbulence or sediment accumulation at the bends, large multiples bends are essential to ensure smooth flow. It becomes a critical tool when a project prioritizes smooth fluid flow, long-term pipe reliability, and low energy consumption of the system.
