Use these sleeves— also known as ferrules— with high-pressure compression nuts and fittings. They withstand about twice as much pressure as sleeves for standard compression fittings, so they're good …
28-10-2015· Compression fittings can be used in high pressure applications and may even become more reliable as pressure is increased as the pressure tends to expand the tube against the ferrule. Although compression fittings are generally considered more reliable than threaded fittings, there are some potential problems.
Allowable working pressures are calculated from an Svalue of 35 000 psi (241 MPa) at –20 to 100°F (–28 to 37°C) for ASME B31.3 and an Svalue of 50 000 psi (344 MPa) for ASME B31.3 Chapter IX. See Elevated Temperature Factors,page 8, for tubing use above 100°F (37°C).
gripping action because it can be taken to higher pressure and is more resistant to the ferrule swaging or indentation. This gripping challenge on heavy-wall tubing may be severely compromised when fittings are under-tightened and / or not properly bottomed in the fitting body prior to installation. A high-quality tube fitting is designed to be more
01-09-2003· Home; Production; Well intervention using rigless techniques. Rigless techniques for well intervention are wireline, coiled tubing (CT) and hydraulic workover (HWO) services that do not require the use of a conventional workover rig and have the capability of performing downhole applications in live (under pressure) wells.
The stainless steel ferrule parts produced by Truex are made from 304 alloy stainless steel. It is known for being friendly for forming and welding, making it a great choice for ferrules. Each ferrule is also bright annealed to allow for ease of crimping. View our Catalog.
12-04-2018· Also, one good thing with ferrules is that you don't get the same kind of loss of contact pressure over time as you do with twisted multistrand wire, the crimping takes care of that.
18-08-2016· Pressure (P) = 2 x S x T / D, Where P – pipe internal pressure in psi T – wall thickness D – O.D. tube S – stress on tube material in psi Flareless type tubing fittings are available in two common styles. Ferrule or Sleeve Type: The ferrule is used to seal against the tapered seat of …
High heat resistant 95% alumina bush ceramic ferrule al2o3 99% sleeve Advantages of ceramic insulator tube: 1. Refractory. 8. High Temperature and Pressure Resistance. High hardness, long service life, not easy to break and wear resistance.
Pressure - Maximum operating pressure of the hose must be greater than or equal to the system pressure. Pressure surges or system "spikes" in excess of the maximum operating pressure will shorten hose life and must be avoided. Temperature - Ambient and fluid temperatures must not exceed the hose/fittings rated design temperature.
It must be highly resistant to pressure, temperature, chemicals and stop humidity from permeating the hose wall. It concerns automotive air-conditioning in particular because there, the freon hose operates in the engine compartment, tightly packed and bent, in high ambient temperature conditions, exposed to vibrations and in contact with car fluids.
20-09-2017· The ferrule is deformed, compressed and clamped around the tube creating a very tight seal able to withstand the nominal pressure of the tubing. The two-ferrule design compensates the tolerances in tube diameter, wall, thickness, and material hardness, giving the connection exceptional leak-free performance (without impacting the mechanical properties of the tubing: the back ferrule …
A ferrule arrangement for use in sealing connections to gas chromatography columns includes a generally tubular metal ferrule with an axial bore to receive a fracturable column with a protective coating. The ferrule has a forward part that tapers to a tip region of the ferrule. A generally tubular former has a socket portion to receive the ferrule and further has an internal conical surface ...
Used in concert with high pressure tubing, these can meet the needs of applications requiring performance exceeding pressures above 10,000 psig, such as hydrogen fuel cells and aerospace. Stay Pure In industries from medical to semiconductor to instrumentation, your application needs inert, contamination-free components.

System Pressure problems Overpressure –Check if something has changed (column, mobile phase, temperature) –If nothing has changed, remove the column and replace it with a union to check if the system pressure is the usual. –If system pressure is high loosen fittings beginning with the last connection in line and working backward to the pump
