Hydraulic Hoses Aren’t Designed To Leak

admin — Tue, 26 May 2015 00:49:06 +0000

Hydraulic hoses are not designed to leak - but those of you who have worked in the field have seen it happen. And when they do, something is wrong. Leaks from high-pressure hydraulic lines are not just messy; they are dangerous. Leaks create slip and fall hazards, fire danger, and they contaminate the environment. Leaks can cause skin burns and, under high pressure, can penetrate the skin. The most common causes of leaking hoses are abrasions and improper assembly. If you work with hydraulic hoses, you should become skilled at inspecting hoses and fixing them when needed.

1. Preventing Problems : Prevent abrasion by using hoses of the correct length and diameter. Run the hose in the manner specified by the manufacturer, making sure it is supported and restrained by all provided hangars and/or brackets. If chaffing guards were originally installed but are now missing; they must be replaced. Do not ignore a damaged outer jacket. This allows moisture to attack the exposed hose reinforcement, leading to rust. Corrosion could lead to hose failure.

2. The Wrong Way to Find and Fix Leaks : What do you do when you find a leaking fitting? Find a wrench and give the fitting another turn? That extra turn could cause a greater leak or cause the fitting to fail entirely. Do not use your hand to find the leak. Use a piece of cardboard or wood instead. Hydraulic fluid is hot and can burn the skin. A pinhole leak, under pressure could actually inject fluid under your skin, causing poisoning, infection, and threaten life and limb. It can and has happened.

3. Test for Tightness : But before doing this, shut the machine off and bleed hydraulic pressure from the line. If the fitting threads were to strip or a connection were to fail under pressure, injury or fire could result from the sudden release of hot oil. The usual cause of a leak at a fitting is improper assembly or damage. Make sure that:

(a) Both ends are clean inside and out, and that no physical damage has occurred;

(b) New seals are used and they have been cleaned and lubricated before installation;

(d) Fittings are incompatible. There are many thread ends, and some, may almost go together properly, but not quite.

4. Proper Assembly of Hose Ends is Important : Hoses that come apart under pressure can whip back with great force and release a lot of hot oil. If the failure occurs at the fitting, the usual reason is improper crimping, an incorrectly cut hose, or a stem that was not inserted into the hose all the way. If you assemble your own hoses, check your crimping dies for wear. On some types of crimping machines, if the dies become worn, the crimp is looser than it should be. Screw type hose clamps are not to be used on pressurized hydraulic hoses.

People who work with any type of fluid piping system know it takes clean, careful; workmanship to prevent dangerous leaks. If you see a leak, report it. If your job requires you to fix the leaks, do it properly and safely.

TEMPERATURE CONVERSION FORMULA

admin — Tue, 26 May 2015 00:34:09 +0000

Celsius is a temperature scale where freezing point of water is 0 degrees and the boiling point is 100 degrees. Used globally in all kinds of applications and used to known as centigrade until the mid of 20th century. The abbreviation is “^oC”.

Fahrenheit is a temperature scale where freezing point of water is 32 fahrenheit degrees and the boiling point is 212 fahrenheit degrees. It is replaced by celsius (centigrade) scale as part of the metrication process but it is used in united states for all kinds of applications to measure the temperature. The abbreviation is “^oF”.

Temperature Conversion Formula

a. The celsius to fahrenheit conversion formula:

a. Fahrenheit = Celsius * 9 / 5 + 32

a. For example: 30 ^oC = 30 * 9 / 5 + 32 = 86 ^oF

b. The fahrenheit to celsius conversion formula:

a. Celsius = (Fahrenheit - 32) * 5 / 9

a. For example: 86 ^oF = (86 - 32) * 5 / 9 = 30 ^oC

4 Easy Steps to Identify Hydraulic Threads

Source : Parker Hannifin Corp., Tube Fittings Division

Machines and equipment are designed and manufactured in every corner of the world. The hydraulic systems alone use countless different types of fittings and adapters with different sealing methods and thread forms. While the sealing method can often be distinguished by appearance, thread forms all seem to look the same, making it difficult and time consuming to identify them when equipment modifications or repairs are needed.

Proper Identification for Profitable Operations

Knowing the correct thread is critical for selecting the right replacement parts for maintenance and repair. Selecting the wrong part can result in damage to the thread during installation, which compromises the pressure-holding capacity and seal reliability of the fitting or adapter. Quickly and properly identifying threads can help maintain safe, productive, and profitable operations.

Six types of threads are commonly used on hydraulic tube fittings – UN/UNF; NPT/NPTF; BSPP (BSP, Parallel); BSPT (BSP, Tapered); Metric Parallel; and Metric Tapered. Four simple steps will help you identify them.

Step 1 – Determine if the thread is tapered or parallel. NPT/NPTF and BSPT are tapered threads while UN/UNF and BSPP are parallel. Metric Tapered and Metric Parallel speak for themselves. In some cases, Step 1 can be accomplished by visual inspection alone. Tapered threads get smaller in diameter toward the end of the fitting while parallel threads maintain the same diameter from start to finish. If this is not obvious by looking at the fitting, use the parallel jaws of a caliper to make a comparison. Furthermore, the presence of an O-ring or the removal of a tube nut is usually an indication that the male thread is parallel. Completion of Step 1 will eliminate three of the six possible thread forms.

Step 2 – Determine the pitch. This can be deciphered using a pitch gage for comparison or by accurately measuring and calculating the number of threads within a given distance. It is much easier to compare threads against a lighted background with a pitch gage. Because some thread pitches are relatively similar, it is advisable to try a number of gages before deciding which one fits best. The result from Step 2 will narrow down the possible thread forms even more because most have a distinct pitch. Consult the “Step 2” column in Table 1 for possible pitches.

Step 3 – Determine the size. Combining the results of Steps 1 and 2 will determine – or help predict, in some cases – the correct procedure for Step 3. There are two methods for determining the thread size – which to use depends on whether the thread is a pipe thread (NPT/NPTF, BSPT, BSPP) or is not a pipe thread (UN/UNF, Metric Parallel, Metric Tapered). Keep in mind that tapered (as determined in Step 1) does not necessarily mean that it is a pipe thread (e.g., Metric Tapered). Likewise, pipe thread can be parallel (e.g., BSPP).

For pipe thread, determine the size by comparing it with a nominal size profile, as shown in Figure 1 (a useful tip – pipe sizes up to 2 in. nominal size can be determined by measuring the actual outside diameter, subtracting ¼ in., then rounding off). For non-pipe thread, the actual size can be determined by measuring the outside diameter (major diameter) with a caliper, as shown in Figure 2.

Figure 1. Determine pipe thread size with nominal size profiles

Figure 2. Determine non-pipe thread size with a caliper

Step 4 – Designate the thread. Technically, this final step does not pertain to identifying the thread. Rather, it is a method of designating the thread type in an industry standard format for others to understand. Examples of the various formats are shown in the “Step 4” column of Table 1. These typically have an indication of the thread size (whether nominal or actual), the type, and – in some cases – the pitch.

Your company’s maintenance and repair professionals can put this easy four-step process to use to minimize machine downtime, avoid the expense of acquiring (and returning) incorrect parts, and help ensure a safe, accident-free work environment.

In Summary: How to Identify Threads

In order to differentiate between the various thread types, all that is needed is this reference chart, a caliper and a thread gage. The most important tool is the thread gage (or pitch gage). This tool, which has a saw tooth appearance, helps determine the thread pitch. It has a specified number of serrations within a certain distance and is (usually) marked accordingly. For metric threads, the pitch is considered as the distance, in millimeters, between each thread. For all other threads, the pitch is considered as the number of threads per inch.

*Step 1* Determine if tapered or parallel	*Step 2* Determine pitch	*Step 3* Determine size	Thread type	*Step 4* Define the Thread (Examples)
Parallel	12, 14, 16, 18, 20, 24	Measure with caliper	UN / UNF (SAE)	Size-pitch, type ¾-16 UN/UNF
Tapered	11½, 14, 18, 27	Compare with profile	NPT / NPTF (American Pipe)	Size-pitch, type ¼-18 NPT
Parallel	11, 14, 19, 28	Compare with profile	BSPP (British Pipe)	G, size* G1/8
Tapered	11, 14, 19, 28	Compare with profile	BSPT (British Pipe)	R, size* R1/2
Parallel	1.0, 1.5, 2.0	Measure with caliper	Metric Parallel	M, size x pitch M14×1.5
Tapered	1.0, 1.5, 2.0	Measure with caliper	Metric Tapered	M, size x pitch, keg or Taper M10 x 1 keg or Taper

*For JIS (Japanese Industrial Standards), the thread can be identified similar to BSPP and BSPT but defined with PF and PT, respectively; for example, PF 1/8 and PT 1/2.
