Vantagem

TorcStark has always been at the forefront of hydraulic bolt tensioning. Our tensioning tools provide a fast, accurate and safe solution for tightening and loosening multiple bolts at the same time using a high-pressure tensioning system. If your project has strict requirements for bolt pre-tightening force, ordinary tensioning tools will not be able to achieve your goal, then bolt tightening machine is the best choice. TorcStark’s standard hydraulic bolt tensioners are designed for general use. Each tool includes a hydraulic cylinder, bridge, puller and socket. The interchangeable adapter kit is suitable for common hydraulic cylinders and can tighten bolts of various sizes. Whether you are tightening flanges in a factory or installing blades on a wind turbine, TorcStark has the tools for the job. TorcStark offers a wide range of Bolt tensioning machines and tensioner pumps to suit various applications and environments. Our tensioner can be designed into any style that meets the needs of customers.

Bolt tensioning is now the preferred method of tightening bolts and studs in all critical applications. Bolt tensioners are designed for a variety of applications, including pipe flanges, heat exchangers, pressure vessels, compressor covers, boiler feed pumps, windmills, etc. In the bolt tensioning, the bolt tensioner uses pure tension to directly stretch the bolt, without torsion shear and lateral force, and no frictional damage to the contact surface of the connection. It is the best method to accurately control the bolt pre-tightening force. Through the bolt hydraulic tensioner, you can pre-tighten or disassemble multiple bolts at the same time, and stretch the bolts before tightening with zero friction of the nut, ensuring extremely high accuracy, speed and uniformity. It is one of the best bolt tensioning tools. Compared with the traditional tightening method, using a bolt tensioner has significant advantages:
Fastener without torsional load
Direct loading will not damage the components.
The operation is simple and quick.
Very high accuracy and repeatability.
Automation is feasible and can be used for critical applications.

Therefore, the hydraulic bolt stretcher is a simple and efficient bolt tensioning equipment. TorcStark is committed to providing customers with the best quality and widest variety of hydraulic stud tensioners, such as bolt tensioning devices for wind power, and subsea tensioners for tightening subsea bolts. Our hydraulic tensioners have European CE and ISO9001 quality certification. They can operate safely and stably in various harsh environments, making bolt tightening simple and easy. The trust and purchase of customers is the best proof of the quality of TorcStark bolt tensioning cylinder.

TorcStark has many years of research and manufacturing experience for bolt tensioners. As one of the world’s best bolt tensioner manufacturer and supplier, TorcStark hopes to provide you with the most suitable bolt tensioner.

Perguntas frequentes

How many types do you have for the bolt tensioning machines?

Basically there are two types, single stage bolt tensioner (also called topside bolt tensioner) and multi stage bolt tensioner. But customized models are also available.

What are the main differences between single stage and multi stage bolt tensioning tools?

In most cases single stage bolt tightener machine is required for example oil&gas, petrochemical industry etc. For multi stage tensioner it’s specially used for wind turbine installation and maintenance.

What information should I provide if I need a hydraulic bolt tensioner?

If any customer wants a hydraulic tensioning of bolts, you’re kindly requested to provide necessary information as mentioned below:

  1. What is the maximum tensile force you need?
  2. Quais são os tamanhos dos seus parafusos? M39 M42 ou então?
  3. Qual é o grau de resistência do parafuso? Geralmente é 10,9 ou 8,8. Se você não sabe a resposta para a pergunta 1, então esta é muito necessária para responder.
  4. Do you need topside or multi stage bolt tightening tools?
Qual modelo devo selecionar para substituir o modelo antigo que estamos usando atualmente?
