Compensator Storage Raiders: Improper Storage and Direct Scrapping? These 5 Steps Help You Save Wasted Money

Compensator Storage Raiders: Improper Storage and Direct Scrapping? These 5 Steps Help You Save Wasted Money

To be honest, the compensator looks pretty solid, but if you don't store it properly, it will be scrapped much faster than you think. A customer called the other day and said that two-year-old pieces had been dug up in the warehouserubber compensatorWhen I touch it, the rubber surface is all sticky, like chewed gum-waste. Tens of thousands of dollars have been wasted like this. Do you feel distressed?

Today, let's break it up and talk about itCompensator storage requirementsFive steps, each step has operation details, follow it, at least three years to keep your inventory good. Don't be too long-winded, the last trick to check the list is especially critical.

Step 1: Choose the right place to store it – temperature and humidity are invisible killers

You must not putcompensatorThrow it in an open corner or in a damp garage. Especiallyrubber compensatorAndNon-metallic expansion joint (fabric fiber expansion joint)These two categories are most afraid of two things: direct sun and humidity.

UV rays can make rubber age, harden, and crack. What about fabric fibers? When the moisture bubbles, it will mildew and rot directly. Do you thinkMetal bellowsIs it all right? Don't be careless. If the warehouse is near the acid-alkali storage tank area, and there is acid-alkali gas in the air, the stainless steel will still rust-don't ask me how I know, in the corner of the chemical plant warehouseUniversal corrugated expansion jointIt's a tragedy.

How to do it specifically?

• Be sure to store indoors, the temperature is controlled between-20℃ and +40℃, and the relative humidity should not exceed 80%.
• Stay away from radiators and air-conditioning outlets, the temperature difference fluctuates too much, and the seals will accelerate aging (such asPTFE compensatorThe sealing ring is crispy in a few months).
• You can only put it outside? Okay, set up a rainshade, and the bottom is raised by more than 200mm, otherwise the ground will be damp,Direct buried (fully buried) type expansion jointThe flange surface is the first to show you.

Tips:Do you have an area in your warehouse near acid and alkali storage tanks? If you have it, hurry upMetal hose、PTFE-lined hoseMove away, even a wall is not safe.

Step 2: Don't unpack the packaging too early-the original packaging is the best protection

As soon as the goods arrive, many masters are anxious to tear the plastic film and unpack the wooden box, and they still chant "check it". When you really want to install it, you will find that the flange surface is knocked in a pit, the bellows is all dust and oil,expansion joint guide tubeThe edges are deformed. You say it was wrong or not?

The rust-proof paper, desiccant and buffer foam in the original factory packaging are according to the manufacturersCompensator storage requirementsDesigned, it is a hundred times more reliable than the wrapper you temporarily find.

1. After arrival, check the model and quantity first, confirm that it is correct and put it back in its original place.
2. The packaging box is marked with "No trampling" and "Rain-proof and moisture-proof". It is best to write larger points with a marker.
3. With flanged protective coverMetal hoseAndDirect buried (fully buried) type expansion jointDon't remove the protective cover in advance.
4. When you need regular inspection, only open a small opening to see the appearance, and seal it back immediately after reading it. Don't try to save trouble and leave it open.

Note:PTFE compensatorAndPTFE-lined hoseThe inner lining layer is very delicate. Once the package is broken, dust will drill in, and it will leak after installation. I have seen a case, just because the packaging was broken, it leaked after three days of running, and it cost more than 60,000 yuan to replace it.

Step 3: Anti-deformation support – especially for metal bellows and rubber compensators

Have you seen one that has been kept for a yearBellowsInto *? That's the consequence of not doing support.Metal compensatorAndrubber compensatorThey are all elastic. If they are stacked vertically or laminated for a long time, the ripples will deform permanently, and they can't expand and contract normally when installed-do you think it's irritating?

• All compensators must be placed horizontally and stacking upright is strictly prohibited.Large diameter thick wall expansion jointAndCompound hinge transverse expansion jointThis kind of long guy should be evenly supported by brackets, with a fulcrum every 1.5 meters, so don't save money on brackets.
• rubber compensatorAndRubber PTFE compensatorThe inside should be inflated or stuffed with clean soft filler to prevent collapse. My recommended method: stuffing rags in, not newspaper (stuck to rubber after moisture).
• Sleeve type pipe expansion jointThe sliding sleeve part of the sliding sleeve must be kept in a free state. Do not tie it with iron wire, otherwise the sliding surface will be stuck.

And guess what? Two days ago, a client placed a boxRotary compensatorIt leaned against the wall vertically, but as a result, the top flange was directly crooked, and the bolts couldn't be screwed up during installation. In the end, it had to be returned to the factory for repair. The round-trip freight plus repair cost was 2,000 yuan gone.

Step 4: Turn over and check regularly-rubber parts and fabric fibers are afraid of pressure and moisture

Don't think let's just let it go. Compensators that are in stock for more than three months have to be doubled every two months. EspeciallyNon-metallic expansion joint (fabric fiber expansion joint)And rubber products, long-term immobility is easy to produce permanent compression deformation due to local compression-this is called "indentation memory", which can't be recovered.

Specific checklist (printed out and posted on the warehouse wall):

• See if the outer packaging is damaged, damp or eaten by insects. Mice love to chew on packing boxes, and when they bite, they will get ashed.
• Open the package to check whether the rubber surface is cracked or sticky-press it lightly with your finger to see the rebound, and it will be wasted if it does not rebound when pressed.
• Metal bellowsAre there any rust spots on the exterior? EspeciallyUniversal corrugated expansion jointAndCorrugated expansion joint for power station industryStainless steel will also rust-in the chloride ion environment, 304 stainless steel still can't bear it.
• Flange sealing surface,expansion joint guide tubeAre there any bruises on the edges? If the guide tube is deformed, it will directly affect the flow direction of the medium, and in severe cases, it will cause vibration and abnormal noise.
• Are the tie rods and nuts rusty? Don't forget a common occurrence:Function of expansion joint tie rodIt is a limit, and it may not be twisted after rusting, so it can't be adjusted during installation.

Note:If slight rust is found, apply anti-rust oil after polishing with fine sandpaper. Never use acid wash. Pickling will destroy the passivation film on the surface of stainless steel and accelerate corrosion.

Step 5: Final inspection before installation-pull rod, guide tube, flange surface must not be missing

It's finally going to be packed, don't rush to unpack it. It takes less than five minutes to do three things first:

1. Check whether the model is consistent with the pipeline design. For example, what you want to pretend isDouble-sealed single-axis circular baffle doorAs a result, the warehouse was takenSingle-axis double-flapper doorWaste half a day's effort and still have to change.
2. Check that the transport limiter is still in place. Many expansion joints come from the factory with temporary tie rods or support blocks (e.g.External pressure single axial expansion joint), these must not be disassembled before installation, otherwise the bellows will be pulled out during transportation. However-after installation, it must be removed according to the instructions, otherwise the compensator will not work. Have you ever seen a temporary tie rod not removed after installation? As soon as the pipe expanded, it exploded.
3. Clean flange sealing surfaces. Wipe the anti-rust oil and packaging debris clean and check for scratches. EspeciallyHigh temperature axial expansion jointAndSpecial hose for vacuumEven a scratch on the flange surface may leak.

Final reminder:For compensators stored for more than two years, even if the appearance is fine, it is best to contact the manufacturer for a pressure test or stiffness test. After all, rubber and seals will age naturally, and it costs money to install and replace them-downtime losses are the real big head.
