Plug-in type flowmeter online installation steps (such as Annubar, Poweriba, Deltaba, Bitoba, etc.) Concise installation guide:
Step 1: Determine the correct installation direction and straight pipe requirements for the Annubar flowmeter;
Step 2: Drill holes in the pipeline.
Note: The pipeline must be drilled. If acetylene gas or other ablation method is used for opening, the maximum flow error after installation can reach 10%.
a. Relieve the pipeline and drain the accumulated liquid.
b. Select the location where you will drill.
For vertical lines, you can open holes at any position in the circumferential direction.
For horizontal pipelines, the location of the openings is based on the fluid application measured by the Ba-type flowmeter:
Measuring the liquid and opening a hole at the bottom of the line;
Measuring gas, opening a hole at the top of the pipeline;
Measure the steam and open a hole at the bottom of the line.
c. According to the above table, determine the size of the opening.
d. After opening the hole, remove the burr from the hole.
e. If it is necessary to install the opposite support, drill a second hole in the opposite direction of the first opening and then remove the burr in the hole.
Step 3: Weld the welded joint to the pipeline,
a. Assemble the flowmeter to the factory-provided welded joints and insert them into the drilled holes.
b. Position the line on the mounting head of the flowmeter (or the transmitter, if it is an integrated meter) so that it is parallel to the pipe.
c, spot welding. The welded joint is fixed to the pipeline, and then the sensor such as Annubar is removed.
d. Before welding, in order to prevent the welding slag from damaging the joint thread, the threaded part is wrapped with thick aluminum foil provided by the factory. Or Screw a protective nut and weld evenly to prevent deformation of the welded parts and complete the welding.
Step 4: Insert the installation type BA flowmeter a. After the mounting connector is completely cooled, install the connector.
b. Install the first seal ring (package) between the seal compression ring and the pre-welded lock ring; be careful not to damage the seal ring.
c. Press the sealing ring into the interior of the connector to the pre-welded locking ring. Repeat the above steps to load the remaining two seal rings and adjust the position of the seal ring openings so that the position of each opening is staggered to 180 degrees.
d. Adjust the direction of the flow meter, and point the arrow mark on the head of the flow meter to the fluid direction of the pipeline. Tighten the Pak-Lok compression nut and the connecting body by hand, and tighten it by hand.
e. Lock the nut with a wrench and evenly lock the nut. The degree of tightening of the nut can avoid leakage. Do not over-tighten the compression nut, as this will damage the mounting components.

Although there are many types of tapping screws, they all have the following similarities:
(1) are generally made of carbonized carbon steel (accounting for 99% of total production). It can also be made of stainless steel or non-ferrous metals.
(2) The product must be heat treated. Carbon steel tapping screws must be carbonized and stainless steel tapping screws must be solution hardened. In order to make tapping screws to meet the requirements of the standard of mechanical properties and performance.
(3) The product surface hardness is high, the core toughness is good. That is, "soft inside strong outside". This is a major feature of tapping screw performance requirements. If the surface hardness is low, it can not be screwed into the matrix; If the core toughness is poor, a twist will break, can not be used. So "inside soft outside steel" is self-tapping screw to meet the use of performance, very important requirements.
(4) The surface of the product needs surface protection treatment, generally electroplating treatment. Some product surface must be treated by phosphate (photostatting), such as wall panel self - tapping screws for photostatting.
(5) Production by cold heading process. It is recommended to use high-speed cold heading machine and high-speed wire rolling machine or high-speed planetary wire rolling machine. High speed is emphasized here to ensure product quality. Only the head of tapping screw produced by high-speed machine is well formed and the thread quality is high.
