One of the optimal designs for pressure testing long objects

Test benches, test cabinets, and test bays are well known and used in combination with high-pressure test equipment in a wide variety of industries, to provide a safe test environment. Selecting the right safe test setup is dependent on various factors and when testing bigger objects the solution often lacks mobility. The longer the test object, the more difficult it is to contain the object in an enclosure. Bigger sized objects are generally pressure tested in a containerized or fixed test bay and since these test bays are usually not in the vicinity of the workshop, lifting and other logistic tasks have to be completed before testing can commence. The logistics obviously increase the time that is needed to complete the entire test process.

Resato now has developed a modular test box that fits in a current workshop setup and provides a lean process. Curious how? We will describe it in this blog.

Efficient workshop use

The modular long tool test box Resato has developed is used in combination with a Resato high-pressure system in your workshop is self-contained. The lid is hydraulically controlled for ease of loading and unloading objects with the use of an overhead crane, transferring these objects from the production/ redress area within minutes to the test box.

Because the test box is located in the workshop, time is saved when transporting the test object, since it does not have to be transported to a purpose-built test bay usually located elsewhere in the facility. Also when a leak is then discovered during testing, it can be quickly transferred back to the production/ redress area for additional torqueing or repairing. The test box can be part of your overall workshop setup and contributes to a lean process.

The modular box has forklift pockets and can be shifted to any other location where it is necessary to test your products as opposed to a fixed pressure test bay that has to rebuild in a different location. This modular test bay will provide an instant pressure test solution complying with your company’s safety standards.

Safety first

Other than loading and unloading objects safely by using an overhead crane, all high-pressure components are covered by thick-walled plated steel, protecting personnel and environment. Both head ends are made out of 70mm solid steel and the sides are double-walled (2x10mm), hence there is space in-between the two walls, which can be filled with sand if necessary. Finally, the lid is made out of 20mm, to ensure that the impact of any projectiles is compensated for. Creating a safe working environment.

Additional safety features are the door switches and door locks, that prevent operation of the high-pressure unit if the test box is in an open and unlocked position. Furthermore, a de-air skid is installed in the test box, which can be operated from the HPU panel for safe de-airing of the objects. Any extra safety requirements can be incorporated into the design of the test box.

Other features of the long test box

Our test box has been specially designed for long objects, such as tubulars and completions objects. We understand that the length of objects is not limited to the standard text box’s length of 5 meters. Therefore, we offer the possibility to add extra length to the test box, in 5 meter-sections.

The box is equipped with a build-in sump pit and a diaphragm pump, to capture spilled and drained test fluids, which will be pumped through a filter back into the fill tank enabling re-use of test media.

The high-pressure testing system (HPU) can be fitted with a dual pump setup and multiple pressure transmitters and test certificates are generated in pdf. format to allow electronic sharing and storage.

Choosing the right testing systems and equipment for your situation

The LTB is an example of how high safety specifications and mobility can be combined into your testing environment. The right testing setup depends on various factors, such as your test protocol and resources, however, many other aspects have to be looked at before investing in the right system or type of equipment.
