Description of Bandlock Closure

Bandlock Closure is working on circular openings of pressure pipes or pressure vessels. At the same time, it can realize a mechanical device that can quickly open or close. So it generally has of cylinder flange, head cover, hook ring or clamp, sealing ring, safety interlocking mechanism, opening and closing mechanism, rotating arm, and pup joint (when necessary).

Structure of Bandlock Closure

The Bandlock Closure opens the head cover structure. Its components include: cylinder flange. An opening device is fixed on the circumference of the cylinder flange. Then the opening device includes a mounting plate. The mounting plate is connected to the cam through the camshaft. A snap ring gasket is installed flatly on the cam, and the camshaft is inserted through the middle part of the snap ring gasket. Then the cam and the mounting plate are fixed by locking pins. A handle is mounted on the side of the cam. The Bandlock Closure fits the launch plate. The Bandlock Closure is also above the head cover.

The plug-type quick-opening blind plate opens the head cover structure of the quick-opening blind plate. The head cover is installed under the mandrel through the gland. The mandrel is also connected to the rotating arm head cover through a pin. The rotating arm headgear is welded to the small end of the rotating arm arc plate of the rotating arm device. The top of the head cover is connected to the opening device through the base.

Because quick opening closures are pressure-retaining structures designed to provide access to pipelines and pressure vessels. So our Quick Closures provide safe and quick access to pipeline and pressure vessels. Then they are built to meet all required international design codes and can be used in horizontal, vertical, inclined or declined applications. We offer Clamp, Bayonet and Ring lock Closures as required by Clients.

Safety requirements for Bandlock Closure extraction and plugging operations in Bandlock Closure factories

1. Firstly, the blind plate pumping and plugging operation shall be subject to operation permit management. Before the operation, it should obtain a “Blind Plate Plugging Safety Operation Certificate” .

2. Secondly, personnel engaged in blind plate extraction and plugging operations should undergo safety education and specialized safety training, and pass the assessment.

3. Then the production workshop should draw a blind plate location map in advance. Then the blind plates will be numbered uniformly and a dedicated person will be responsible for them. The blind plate extraction and plugging operation unit shall operate according to the drawing.

4. Also, operators should identify harmful factors in the on-site working environment and formulate corresponding safety measures.

5. Then special personnel should be assigned to supervise the plugging operation in the quick-opening blind plate factory.  It does not allow Guardians to leave the work site.

6. Carry out blind plate plugging operations in complex and dangerous places. Bandlock Closure factories should develop emergency plans.

7. At last, when performing blind plate pumping and plugging operations on pipelines and equipment with toxic media, the system pressure should be reduced to the lowest possible level. Workers should wear suitable protective equipment.
