As a key source of electricity, production and resource creation, the petrochemical industry is one of the most important industries in the world. The petrochemical industry occupies a very important position in the whole heavy industry. In the petrochemical industry, however, bolting tools are a top priority.

Petrochemical plants mainly use explosive and potentially volatile compounds, so safe and reliable bolting tools are required to ensure the fastening of flanged pipes, pumps, valves and other equipment.

In order to ensure the quality and safety of the workers who operate the bolted connection, it is necessary to use some special industrial bolting tools for petrochemicals to tighten the bolts in the same way.

TorcStark provides dedicated bolting tools and solutions for bolting in the oil and gas industry, suitable for both onshore and offshore applications.

In the oil and gas industry, frequently used industrial bolting tools include hydraulic wrenches, hydraulic pumps and bolt tensioners.

Hydraulic Torque Wrenches

Hydraulic torque wrenches tighten bolts by applying tightening force to the nut. Nuts and bolts generate sufficient clamping force to ensure leak-free flanged pipes, pumps, valves and other equipment. Hydraulic wrenches are suitable for almost all bolted connections and offer huge advantages such as speed, accuracy and flexibility.

The best choice for applications with limited space

In the petrochemical industry, there will be many bolts in narrow spaces that need to be tightened, and it is difficult for general-purpose bolt tools to tighten bolts accurately, quickly and safely. ATEX certified TorcStark KLCD, WHCD, JND, CLCD series hydraulic torque wrenches are designed for low profile and small radius operation, ideal for bolt tightening in limited or confined spaces.

The most versatile bolt tightening tool

In the petrochemical industry, when performing maintenance on offshore oil rigs or attaching heavy bolts, operators rely on torque wrenches that work reliably every time. TorcStark MXTD, ATX, BXTD series torque wrenches are ATEX certified to meet the reliability requirements of heavy-duty applications.

Accessories for hydraulic wrenches

Bolting tools hydraulic wrenches in the chemical industry need the assistance of sockets when adapting bolts of different sizes. Various sizes of low-profile wrench sockets and square wrench sockets are available for most bolt sizes. The operator only needs a wrench and sockets of various sizes to complete the tightening of various types of bolts. TorSctark’s sockets are safe, reliable and durable.

Bolt Tensioner

While torque wrenches and tensioners can accomplish the same goal of tightening nuts and bolts together to maintain joint integrity, the tensioner is tensioning the bolt rather than torque rotation. Tensioning therefore produces a more precise load and is usually applied to larger bolts.

In these types of harsh environments, bolting specialists rely on bolt tensioners. Bolt tensioners are mainly used to tighten ANSI flange bolted connections, and when tightening flange bolts, multiple bolts need to be tightened at the same time, which can significantly reduce the risk of leakage.

Flange-specific single-stage bolt tensioner

In the petrochemical industry, flange bolted connections are one of the most common bolted connections. The hydraulic pump can control multiple bolt tensioners at the same time to stretch and tighten the bolts at the same time, which can effectively prevent leakage. TorcSatrk HLD, DLD, TSD, ESD and more bolt tensioners provide accurate and reliable performance in general and multipurpose tools.

Fastening of pumps, valves and other equipment in the petrochemical industry

In the petrochemical industry, the leakage probability of equipment such as pumps and valves can be very high. Corrosion and oxidation of various chemicals are very easy to cause leakage. TorcStark’s CY, DN/HN series super nuts and hydraulic nuts are subjected to a large amount of anti-corrosion and anti-oxidation treatment on the surface, so that the valves and other equipment tightened with this nut are fastened, safe and reliable.

Hydraulic Torque Pumps and Hydraulic Tensioner Pumps

Hydraulic pumps provide constant power for torque wrenches and tensioners. The hydraulic pump is designed and manufactured with a stainless steel frame, which can ensure normal work in harsh environments. Advantages such as fail-safe tips, portability, compact design, and fast operation help keep operators safe and reliable when performing bolting maintenance, plumbing repairs, bolt tightening, etc.

Condition with easy access to electricity

The principle of the electric torque pump is that the kinetic energy generated by the motor acts on the hydraulic oil, and the hydraulic oil generates pressure to control the torque wrench to tighten the bolts. The electric torque pump is simple to operate and easy to carry, and is one of the most commonly used hydraulic pumps in the petrochemical industry. Torsctark EMP304, EMP204 Electric Torque Pumps produce high and precise pressure, making them the best choice for driving torque wrenches.

Explosion-proof conditions

In the petrochemical industry, explosion protection is a very important job. Therefore, this guideline should also be followed when selecting the power source for the wrench and tensioner. TorcStark has a special explosion-proof torque pump FB204 and offers a variety of styles to choose from. Pneumatic pumps that generate power through air compression also have a certain explosion-proof effect. In some cases where explosion protection is not particularly strict, the QMP304 pneumatic hydraulic pump provided by TorcStark can be used, and the QMP2004 pneumatic pump for bolt tensioners can also be used.
