Piping Technology & Products, Inc., recently performed its snubber cycle test to prove the durability of a MSA 35 mechanical snubber manufactured for an engineering and construction company at Pine Bluff, Arkansas.
The cyclic test, performed using PT&P’s in-house, horizontal, hydraulic press, is designed to test snubbers at their two modes of operation. At high rates of loading, especially impact, the snubber is expected to provide very high resistance to movement. At low speeds snubbers are to provide very low resistance to movement. Testing a snubber at a low speed displays the normal wear and tear over an extended period of time.
In this case, a cyclic test was performed, in which the MSA 35 Mechanical Snubber with a load rating of 50,000 pounds and design travel of 6 inches was measured at a slow speed response. The low speed force remained at a fairly constant 500 pounds for the 50 hours and 5000 cycles it sustained. This value meets the common criteria that the drag force should be 2% or less than the rated load.
In addition to the snubber cycle drag test, Piping Technology & Products, Inc. has administered other tests such as the burst test for expansion joints. The tests executed by PT&P allow companies to attain the most precise and reliable data available to them. Using this to their advantage, customers will be able to compare data about the recently ordered products, to their individual standards of dependability and durability.
Piping Technology & Products, Inc. and its wholly owned subsidiaries are recognized leaders in manufacturing pipe hangers/pipe supports (variables, constants, cryogenic supports cold shoes, hot shoes, mechanical/hydraulic snubbers, slide bearing plates), expansion joints/compensators (metallic, fabric, rubber, slip-type) and ASME Code Fabrication. PT&P has engineering drawing production stress analysis and full in-house finite element analysis that are used to prove designs. The design software is developed in-house and the calculations contrived are further checked using hand calculations.

A test shot to test out my Toyo 10x8. It looks like everything is working as it should.

second test with the SB-600 with the radio trigger. A part of my work is making photographies for real estate. A recurrent problem is the huge luminosity difference between windows and back of the room, especially with an ultra wide angle.
In this house, it's reinforced by the veranda at left, much brighter than the living room in the right corner (upper image). I tried the SB-600 on-camera, but it doesn't solve anything. So I bought those cheap transceivers.
I left the SB-600 with an omni-bounce behind the stairs, and made a few trials and errors until I got a sufficiently good one - I was in a hurry, people were eating just outside the field. Composition is better in the first one.
An added benefit is the color temperature of the flash corresponds to the daylight, not incandescent like the upper one. I think I need a second flash behind me.
I always snap a test shot indoors to make sure the camera's ready and working. It's worth it for the one time in twenty when it tells me "NO CF CARD". I quite liked this one.
Test print in low quality. I've made this test of my doll head's lid to check the size and some details.

finally hooked up to the pump. It... kind of works, there's some heavy overshoot and I will have to tweak the controls a bit. Other than that there are no problems what so ever, so I'm quite happy.
focus the left eye on the left image!
Right shot on the right, see next half of radio button.
Camera shifted from right to left on my X-Y rack..
See next image for the camera mount.
I used the Instagram Layout app to set up the two images...
These work well on an iPad, as you can pinch in and out to adjust the separation for your eyes..

What?! It's wet there! I've been a girl for a long time now.
I wanted Southeast Asia to think I'm pretty.
