What is a Stopple plug?
What is a Stopple plug?
A true innovation in plugging technology, the STOPPLE® Train system allows two plugging heads to be inserted through a single fitting. When the void between the heads is bled down, the seal on the secondary head provides double block and bleed pressures up to 1,480 psi.
What is a hot tap fitting?
Hot Taps or Hot Tapping is the ability to safely tie into a pressurized system, by drilling or cutting, while it is on stream and under pressure. Typical connections consist: Tapping fittings like Weldolet®, Reinforced Branch or Split Tee. Split Tees often to be used as branch and main pipe has the same diameters.
What is a TOR pipeline?
THREAD-O-RING™ Fittings (T-O-R) are used with TDW STOPPLE® Plugging Machines as purge and equalization fittings. They can also be installed during new construction and used for blowdown connections on either side of a block valve.
Why you shouldn’t use hot tap water?
Hot water systems like tanks and boilers contain metallic parts that corrode as time goes by, contaminating the water. Hot water also dissolves contaminants in pipes faster than cold water. And no, boiling the water does not make those contaminants (like lead) go away.
What is hot tapping and cold tapping?
Hot tap / Cold tap is a method of employing an under-pressured drilling machine to provide a branch off pipeline from existing main pipe. Cold tap is used for system that carry flammable medium. Cold tap prevents ignition, especially fuel line..
Who is the founder of systematic desensitization?
Systematic desensitization, as originally developed by Joseph Wolpe, was theoretically based on reducing anxiety by causing a response antagonistic to this anxiety to occur in the presence of the anxiety-producing stimulus.
How does systematic desensitization work for claustrophobia?
Most phobias respond to exposure, but it is associated with high dropout rates and low treatment acceptance. Systematic desensitization response is more moderate. Some studies suggest that virtual reality may be effective in flying and heights. Cognitive therapy is most helpful in claustrophobia.
What was the first phase of Wolpe’s desensitization method?
Wolpe’s method of systematic desensitization by reciprocal inhibition involved three phases. The first phase typically involved deep muscle relaxation exercises. Wolpe assumed that one could not be both relaxed and anxious at the same time. The second phase was hierarchy construction where the client rank ordered stimulus features.
What’s the best way to desensitize an area?
Tap the sensitive area into a pillow or cushion. 3. Roll the area along a dowel, or roll of putty, or use an empty deodorant, lip balm or perfume bottle with a roller tip and roll the ball over the area. 4. Using a small massager or electric appliance (shaver/toothbrush), massage along the sensitive area. 5.
