Meifeng plus blue car with urea reminds you: urea is not regular, card friends tear two lines!

"Wandering Earth" "brainwashing" lines

The friends who have seen the movie know that these few rhyming reminders are the most powerful implants in the whole film. As the first wave of the new year, this set of "brainwashing bags" quickly spread to reality as a urea for vehicles. One of the drafting units of the national standard, Meifeng plus blue car with urea can miss this set of posters must be "fit".

Meifeng Jialan reminds you: Urea is not a regular card friend two lines of tears

So, what harm does the use of irregular car urea have to the vehicle? Next, let's take a look:

The vehicle urea mainly plays the role of purifying the exhaust gas in the vehicle, and can react with the nitrogen oxides in the exhaust gas to reduce the emission of nitrogen oxides. Now the detection of the exhaust gas of the heavy truck passenger car is more and more strict, and the urea is not needed. not to standard. Vehicle urea also optimizes engine performance and fuel consumption and reduces diesel consumption.

The so-called cheap and not good goods, in the transportation industry, this line is even more vivid. Some card friends took into account the cost problem, but did not consider the problem of urea quality. The use of inferior urea led to many failures in their car. So, what kind of damage will the car cause when using inferior urea?

Meifeng Jialan reminds you: poor quality urea damage urea pump

The production standard of urea for vehicles is strict. It consists of 32.5% high-purity urea and 67.5% deionized water. Some enterprises use ordinary water instead of deionized water to reduce production cost, but the urea used in this production cannot meet the requirements for use. , is a non-conforming product. The urea solution produced by non-deionized water will also cause the impurity content to exceed the standard, block the filter, the urea solution conveying pipe and the nozzle, reduce the atomization effect of the SCR system, and excessive impurities may even damage the urea pump.

Meifeng Jialan reminds you: poor quality urea damages the urea mouth

The urea nozzle is located in the exhaust pipe and is in a high temperature environment for a long time, and it is cooled by the circulation of the urea solution when working. If the urea solution is not cooled, the urea nozzle is liable to be damaged.

Meifeng Jialan reminds you: poor quality urea damage metering pump

If the concentration is not up to standard, it will lead to the occurrence of excessive discharge failure. The final result is that the engine torque is immediately reduced, and the vehicle is weak, which will raise the freezing point of the solution. In cold conditions, the metering pump will freeze.

Meifeng Jialan reminds you that inferior urea crystals block the pipeline

If you do not use or use inferior vehicle urea for a long time, the urea crystal will block the pipeline, the nozzle and the pump body, resulting in partial or complete system damage, and the maintenance cost will not be too low. In addition, in the exhaust gas treatment device, the ambient temperature at which the nozzle is placed is very high. If it is normally operated, urea can partially cool down, and if it stops working, it is easy to burn out.

Here to remind card friends, buy urea must choose a regular product, unqualified car urea products damage the vehicle, not worth the candle.

Cementing Tools

Bow spring casing centralizers

Bow spring centralizers, both welded and non-welded is to help center the casing in the wellbore, allowing even distribution of the cement around the casing during cementing operations according to API10D standard size from 4-1/2" to 20".

Feature :

A) Designed for high restoring force and low starting& running force.

B) End collars are designed with self-locking action,which are easy to assemble.

C) Undergo special coating process to prevent from rust.

D) Can be shipped in half assemble condition for economy in shipping and storage costs.

E) Specification:4-1/2" to 20". any special size or combination available on request.

Technical parameters:

Note :â… (single bow),â…¡(double)

Cementing plugs:

Cementing plugs from high performance material such as rubbers and phenolic resins.our cementing plugs are specially designed with a positive wiping action to ensure that the casing is clean, we have both conventional standard plugs and non-rotating plugs.

Top plugs

The top cementing plug is designed to exert continuous pressure on the casing wall. The core is made of aluminum or phenolic depending on the application and well conditions, the tapered base fits the cavity of the bottom plug initiating a positive seal. A solid rubber top plug is also available.

Bottom plugs:

Like the top cementing plug,the fins and tail section provide positive wiping action. Fins also serve as a seal while cementing. The core of bottom plug is alao made of special material such as aluminium or phenolic resins depend on the application and well conditions, a rubber diaphragm at the top bottom plugs ruptures after the plug is seated allowing cement to flow through

TECHNICAL PARAMENTERS

Float collar and float shoe

Float equipment serves the backbone of casing equipment used during primary cementing operations, float equipment guides the casing to total depth and prevents contaminated mud from entering the casing. Also,it provides a landing point for casing wiper plugs, reinforces the lower end of the casing string, and ensures greater accuracy of cement slurry displacement.

FEATURES:

API 5CT,API 5B,API RP 10F rating,china petroleum department standarc SY/T5618-2000.

Rounded nose profile helps guide the casing string(only for float shoe).

The valve is made with phenolic material and molded with high strength concrete. Both the calve and concrete are easily drillable with PDC or rock bits.

High strength design ensure excellent performance for flow endurance and back pressure holding.

Automatically non-rotational groove design ensures corresponding cementing plugs drilled out quickly(only for non-rotating float collar).

Single valve and double valve versions are available. Spring structure and bal structure valve are available: insret type and normal type are available.

Material and size:

API CASING GRADE: J55,K55,N80,P110,L80,etc.

SIZE VARY FROM 4"TO 20"

AVAILABLE CONNECTIONS:

API5RD CONNECTIONS:LTC,STC,BTC

Solid rigid casing centralizers

Rigid centralizers are an integral part of the cementing process. They provide the mechanism that centers the casing in the hole and allows uniform cement flow around the casing to help protect it at all point. Several styles of centralizers are available for matching different well specification and hole size,including turbulence generating designs that help clean the annulus and distribute the cement more evenly and uniformly. All models offer ample clearance for fluid passage and are extra effective in centering the casing, even in highly deviated hole and improve cement flow by reducing the effects of channeling.

Technical parameters

Note: GF series rigid casing centralizer, classified as straight strip type (typeâ… ),spiral(type â…¡),roller type(type â…¢).

Stop collar

Stop collar is used to hold centralizers or cement baskets on any position casing, which ensures the position of centralizers or cement basket to meet the design, the stop collars are available in two types hinges type,slip on type, the stop collars can be installed on casing to limit the axial movement of centralizers and cement baskets.

Usage

1. Fastening screw stop ring when use, first set into the casing ,and then using a wrench to tighten the screws.

2. Fixed screw type when use ,first set into the casing,and then insert screws,Type in with a hammer.

3. Snap fit stop ring, direct stop ring button on the casing,use pin lock, then knocked into the screw.

Hinged bolted stop collars

An economical collar suitable for sub-critical annular tolerances,available in the size range 4-1/2" to 20",it has a cross bolt design which makes it an efficient and user friendly device.
