Perforating Gun Pipe - China

Perforation is an extremely important technology in the petroleum

exploration and development.

It is also one of means to improve the

recovery of oil and gas wells.

In perforating operations, perforating

bullets need to use perforating gun pipes or perforating gun barrels as

gun carrier to position the perforation direction and protect oil casing

in the explosion process.

The requirements for its quality and

performance, especially its transverse impact toughness requirements are

very strict.

Steel tube for perforating gun is mainly used for producing

perforating gun body in oil and gas wells.

The standards and steel grade

include API SPEC 5CT, 33Mn2V and 32CrMo4 - Perforating gun pipe is

composed of gun-barrel, spearhead, gun breech, sealing element and other

components.

Advantages

1 - Steel tube for perforating gun is made from 25Mn2V and 32CrMo4 (30CrMo) materials.

After testing, its performance, dimension and inspection all comply with the set requirements.

JST products have high dimensional control accuracy and stable performance.

2 - The size of cold rolled perforating gun pipe will change a little after heat treatment and straightening, especially the pipe end diameter will produce a certain amount of reduction.

Cutting two pipe ends can solve the problem of pipe end reduction so as to achieve customers’ requirements for the dimensional accuracy and to meet the requirements of technical specifications for steel tube for perforating gun.

3 - The cold drawing unit of JST perforating gun pipe is configured with one φ76 perforated pipe mill, four sets of φ50 perforation units, 28 sets of 5-120 tons cold drawing machines, straightening machine, testing equipment, etc.

4 - We own two professional heat treatment production lines configured with advanced heat treatment equipment, making furnace temperature is equal or less than 5℃ and ensuring stable heating temperature.

We also configure the rotating spray cooling system to fully guarantee water quenching uniform cooling of steel tube for perforating gun.

There are two sets of Siemens electronic control six roller straightening machine to ensure the straightness of tubing and casing after heat treatment.

The two heat treatment production lines for perforating gun pipe can process tubings and casings with the length of equal or less than 13.5 m (φ114-φ406 mm) and the length of equal or less than 12.5 m (48 mm to 180 mm).

The annual productions of tubing are 150, 000 tons and 50, 000 tons.

5 - Our proprietary grades allow us to offer the best solutions for each customer’s particular well conditions.

6 - JST steel tube for perforating gun (perforating gun pipe) is manufactured to the most exacting quality standards.

We hold a global ISO 9001 registration for our operations, which follow a uniform quality policy and apply a rigorous quality management system.
