What does a bad flex pipe sound like?
When an exhaust flex pipe fails, a car will sound as though it has no exhaust system. Exhaust flex pipe leaks can also be the result of the car bottoming out and tearing on a curb or driveway. It’s not always a simple task to detect a flex pipe exhaust leak. However, there are some sure-fire ways to tell if your exhaust flex pipe is leaking.
Is flex pipe good or bad for exhaust use?
There might have been a crack (causing a leak) that got larger, causing part of your pipe to drag or hang from the vehicle. If you notice any of these signs, you may have a flex pipe exhaust leak. It’s extremely important to replace your flex pipe because a broken one can cause serious harm to personnel in the generator engine room.
What is the best way to fix flex pipe?
- Immediately turn off the water supply upstream of the leaking pipes.
- Drain the water from the damaged line and ensure that the area to be patched is clean and dry so that the epoxy will properly adhere to the pipe.
- Tear off enough plumbing epoxy putty to fully cover the surface around the leak.

Can a flex pipe cause check engine light?
The flex pipe is a common repair on your car. Most shops just weld in a new one, or that section of pipe can be replaced as a whole. Almost every time I would see and hear the pipe leaking at the dealer, the Check Engine Light would be on. The most common code for this would be P0133, O2 sensor slow response.Jul 20, 2016
Why is the exhaust flexi pipe important?
The exhaust flexi pipe absorbs vibrations produced by the engine, preventing the other components to be affected .
How do I replace a Flexi exhaust pipe?
To do the replacement, it will first be necessary to loosen the hose clamps of the exhaust flexi pipe in order to unmount it. Then, install the new flexi pipe. For that, unscrew the hose clamps to make it easier to mount the part on the exhaust line. Once placed, tighten the clamps again.
What type of braiding is used in a diesel car?

How much deflection does a flexible pipe have?
As a general rule, flexible pipes will deflect at least 2 percent without structural distress. Most flexible pipe material standards allow up to 5 percent deflection. Deflection is limited to 2 percent if the flexible pipe has a rigid lining and coating and 3 percent for a rigid lining and flexible coating. Flexible pipes include steel, ductile ...
Who invented buried flexible pipes?
In 1941, Marston’s student Merlin Spangler, known today as “the father of buried flexible pipe design,” published another ground-breaking paper, “The Structural Design of Flexible Pipe Culverts,” in which he derived an equation, the Iowa Formula, for predicting the ring deflection of buried flexible pipes. Spangler would later become chairman of the Culvert Committee of the federal Transportation Research Board. In 1958, Spangler’s student, Reynold Watkins, published “Some Characteristics of the Modulus of Passive Resistance of Soil – A study in Similitude,” in which he solved a fundamental flaw in the dimensions of a modulus of passive resistance in Spangler’s Iowa Formula, defining a new modulus of horizontal soil reaction, E’, in the Modified Iowa Equation. In later years, other significant contributions came from A. Howard, J. Duncan, J. Hartley, F. Heger, T. McGrath, M. Zarghamee, and others that now enable the external load design of rigid and flexible pipes to be an even more exact science.
Why is the load difference between rigid and flexible pipe higher?
His assertion that the load on a rigid pipe would always be higher than the load on a flexible pipe due to the differences in interaction between each type of pipe with surrounding soils was therefore corroborated . The study also verified the presence of a plane of equal settlement which Marston had originally predicted purely based on mathematical reasoning.
What are the two types of loading conditions of buried pipes?
In his analysis of external loads on buried pipe, Marston defined two main types of loading conditions of buried pipes, a ditch conduit (referred to as trench load condition in present day nomenclature), and a projecting conduit (referred to as an embankment condition in present day literature), Table 1.
What is the life span of a buried pipe?
Whatever the material type, all are expected to provide some minimum service qualities: prevention of leaks, which ensure that potable water isn’t compromised by contaminants entering a piping system and that wastewaters do not pollute soils and existing sources of groundwater, and most importantly, that the structural soundness of a buried pipe system results in a minimum service life of 50 to 100 years. The latter can only be ensured through a thorough understanding of and designing for the loads to which a buried pipe will be exposed, its response to the loading, and the interaction mechanism between the pipe and surrounding soils.
Why are there buried pipes?
Buried pipelines for the conveyance of potable water and sanitary sewers form the bedrock of our civilization. The very basic services that we take for granted, such as a running faucet with clean drinking water and the ability of our wastewater to be transported away from our homes and businesses for treatment and release into the environment, are possible because of the vast network of buried pipes that lie hidden beneath roads and the concrete jungles that define the large urban centers that are our cities.
How does the width of a trench affect the load on a rigid pipe?
As can be seen from Equations 2 and 3, the width of a trench directly affects the loads imposed on both rigid and flexible pipes. In the case of a flexible pipe, where the pipe stiffness and side fill stiffness are essentially equal, however, the diameter of the pipe also affects the magnitude of the load. For identical conditions of installation, then, the ratio of the load on a flexible pipe to the load on a rigid pipe is equal to the ratio of the pipe diameter to the width of the trench.
What is flex pipe?
A flex pipe is flexible piece of pipe that allows the exhaust system some flexibility. Flex pipes are an essential part of any front wheel drive vehicle and on most all wheel drive vehicles.
How to tell if exhaust pipe is leaking?

If there's a crack in your flex pipe, it will cause an excessively noisy engine. Your pipe might be producing a hissing or tapping sound that can get louder when you accelerate.
Can you replace a flex pipe with a straight pipe?
Additionally, can you replace a flex pipe with a straight pipe? No, never replace a flex pipe with a solid pipe. The reason some cars have a flex pipe and others don't comes down to the material used to make the exhaust and engine position and vibration from the engine.
What is flex pipe?
The flex pipe is made of metal strips woven into a lattice, and thus can withstand exhaust gas heat. Higher quality flex pipes will be made of stainless steel.
Where are flex pipes located?
Flex pipes are typically found where the exhaust manifold meets the downpipe or mid-section of an exhaust, which is closer to the engine than to the exit tailpipe.
What is exhaust flex?
What Is an Exhaust Flex Pipe? Exhaust flex pipes are a flexible metal pipe sections that are used either in areas where an exhaust pipe needs to be flexible, or to repair a damaged exhaust system. While they are all-metal, it is common for one to fail and require replacement.
What is flex pipe?
A flex pipe is a kind of metal bellows. It’s a flexible piece of pipe that creates some flexibility within the generator exhaust system. It basically acts as an exhaust pipe connector. They are typically made out of forged or stainless steel. What are the signs of a flex pipe exhaust leak?
What does it mean when your exhaust pipe is hanging?
Hanging exhaust pipe: Obviously, if your exhaust pipe is hanging, you have an exhaust problem. There might have been a crack (causing a leak) that got larger, causing part of your pipe to drag or hang from the vehicle. If you notice any of these signs, you may have a flex pipe exhaust leak.
How to tell if your exhaust pipe is leaking?

What is PEX pipe?
Cross-linked polyethylene (PEX), a type of flexible plastic, is currently replacing traditional copper and galvanized steel as water supply lines in both new construction and remodeling projects. You’ve probably seen rolls of blue and red PEX pipe in the plumbing aisle of your local home improvement store, but might not know that this colorful tubing now makes it possible for enthusiastic DIYers to replace their own leaky water lines instead of calling a pro. Read on to learn more about PEX—what it is, where it can be used, and all the pros and cons of this popular plumbing material.
What type of PEX pipe is used for hot water?
Blue PEX pipe carries cold water. White PEX pipe can be used for either hot or cold water. Gray PEX pipe, like white, can be used for either hot or cold water (although not all DIY centers carry gray).
What type of fittings are used for PEX?
Hundreds of types of fittings, usually brass, are available for connecting PEX to existing copper or steel pipes, and for making connections to fixtures. Fittings are also available for connecting pipes of different sizes. The following five methods are used for making the connections watertight. Photo: amazon.com.
What is PEX tubing?
Choose the tubing best suited to your needs: PEX-A is manufactured using peroxide. This type of PEX is the most flexible of the three types and is suitable for use in all home water-supply plumbing needs.
What color is PEX?
Water flows silently through PEX, eliminating the “water hammer” noise associated with metal piping. Color-coding (red and blue) make it simple to distinguish hot and cold supply lines. PEX can be connected to existing metal supply lines with the correct fittings.
What is the advantage of PEX pipe?
PEX has a distinct advantage over these materials because of its flexibility, which allows one end of PEX pipe to connect to a PEX manifold (the main water control system) and then wind through walls and floors—uninterrupted—all the way to an individual fixture.
How long is a PEX pipe?
PEX is available in a variety of lengths, from short 10-foot pieces (for small repairs) to rolls over 500 feet long, which are used to install a home’s entire water supply system. PEX pipe ranges from 3/8- to 1-inch in diameter and its color-coding makes it a snap to identify what a specific pipe is used for. Although there are three types of PEX (see Label Lingo, below), the different colors don’t connote the distinctions; they simply make it easy for the installer to identify which lines carry hot water and which carry cold.
