KC. Ratchet Drive Outside Line-up Clamps have been the quality leader of the pipeline industry for many years. This line of KC clamps are of the screw type and are operated with a reversible ratchet wrench supplied with each clamp. Along with conventional design, these clamps have two features that make them superior to other clamps. First, the inside diameter of the clamp is machined to fit the OD of the pipe being aligned. gas works park events This machining operation produces a true bore with parallel pad faces, thus allowing each pad to fully contact the pipe surfaces to aid in accurate alignment of the joint. Secondly, KC. clamps are extremely rigid, being constructed of heavy rectangular bar stock rolled the "hard" way; a design which produces maximum rigidity for the weight of the stock being used. This rigidity enables the clamp to resist springing and distortion when clamping out-of-round pipe. These two qualities of accurate bore and high rigidity combine to produce the best possible joint alignment.

The heart of the KC. Ratchet Drive Clamp, the screw, is made of alloy steel and is of sufficient diameter to withstand the stresses imposed by rigorous service. arkansas gas prices The screw threads are of acme configuration precision cut for maximum strength and long periods of smooth operation. Clamp screws are protected from dirt contamination by heavy telescoping tubular guards, and grease zerks are provided in the steel nut assemblies to allow lubrication of the screw threads and bearing.

Clamp pads are made of rectangular steel that is laid flat to maximize pipe contact and minimize the distance between pressure areas. After the pads are welded in place on the rings, they are bored to proper size and contour to accurately fit the pipe to be clamped. This feature, in combination with the clamp’s extreme rigidity and strong alloy screw, results in greater clamping pressure. This pressure is evenly applied to the pipe insuring proper alignment before welding.

The Deadweight Gauge is the most accurate instrument available for the pressure measurement. Repeatable readings with accuracies of 0.1%. 0.05% and 0.02% of measured pressure are obtainable.The device does not require recalibration unless the components have excessive wear of weights. electricity worksheets for 4th grade It can be easily transported and set up in the field, requires minimum maintenance and is simple to operate.

With the addition of a pressure pump, valves and pressure connections, the hydraulic Deadweight Gauge becomes a Deadweight Tester and can be used to calibrate pressure transducers and other, less accurate dial faced types of pressure gauges. The pneumatic deadweight instruments are considered testers since they deliver air and accurate pressure using an unregulated supply.

Primary pressure standards are generally more accurate than secondary pressure standards. ortega y gasset revolt of the masses A primary pressure standard must revert to fundamental units of mass and length. These fundamental units can be determined with a high degree of precision. The physical standards for a deadweight tester and gauge are traceable to NIST. Deadweight Testers and Gauges also have excellent sensitivity. Low pressure models with large diameter pistons have higher sensitivity at the lower end of their range and are recommended for checking orifice meter static pressure in gas distribution systems. Sensitivity of 0.1 psig and 1.0 psig are typical.

We are also pleased to offer the Vaetrix eGauge1 from Taylor Valve with a state-of-the-art display that provides a large view area for ease of reading. electricity bill calculator The back light capability makes it ideal for field service even in low light conditions. Unmatched performance, solid construction, accuracy and distinctive design all set this gauge apart from any other pressure gauge on the market. Greater portability, much faster and more convenient to use than a deadweight tester. The gauge is more durable and reliable than the most expensive mechanical pressure gauges manufactured to date.

Powered by four AA batteries, the eGauge1 is designed to deliver up to 250 hours of continuous, uninterrupted service. Thanks to its unique combination of low power consumption and high memory capacity in excess of 100,000 data points, the eGauge 1 is ideal for long-duration testing and logging of pressure and temperature conditions in field applications. Vaetrix gauges are used throughout the oil and gas industry, with a reputation for excellence and performance under the most difficult conditions.
