Note of installationUsable lifeLife of the Joint varies by many factors, and cannot be specified exactly.

1 As to positioning of Pump, Joint, and other parts, please refer to the sketch.

If Check valve is mistakenly installed between Pump and Joint, the Joint will be damaged by reverse flow pressure.
Install proper Pressure gauges on inlet side pipe before the Joint, and on outlet side pipe between the Joint and Check valve.
And always check loading pressure and its alteration.

1 Standard Usable Life : about 3 to 10 yearsC)2 Operation condition : ■Max. working temperature • • • Normal temperature (0〜40°■Max. working pressure • • • 0. 98 MPa (lOkgf/㎠)■Stop/start frequency • • • 10〜20 times/day■Operating hours • • • Less than 10 hours/day■Installation• • •Properly aligned and reasonable pipe installation with proper firm support.

Slice valveStandard Usable Life will vary very much depending on installation, deflection load, operating hours, etc.
Therefore please consider it as rough reference.
Further, we would like to to ask you to execute inspection and maintenance, in order to judge the life properly and to avoid any accident.

Check valve
Flexible jointFlexible jointWe set up the Standard Usable Life as follows under normal and average operation:ReducerFactors to shorten the life

Delivery sidePlease note that the life will be shortened by the following cases.

Pump■When operated for a long time at high pressure near max. working pressure.
■When operated for a long time at high temperature near max. working temperature.
■When operated for more than 10 hours a day.

2 Please install the Joint to the pipe in the allowance of the Extension, Compression, Lateral deflection and Angular deflection.

ExtensionCompressionLateral deflectionAngular deflection■When operated with big pressure variation.
■In case of outdoors use, when operated for a long time without putting cover.
■When operated at max. allowable angle deflection.

Inspection for maintenanceUsable life of the Joint differs depending on operation condition.
After the usable life, some improper condition like leakage may happen.
In order to find out abnormal condition in early stage, we would like to ask you to execute inspection and maintenance.

3 Estimating considerable transformation and deflection of the Joint,（1）Kinds and time of inspection4 When fixing the Joint to pipe, get accurate dimension, positioning and alignment,1.Completion inspection ------When completed.
Check and record that it is properly installed under reasonable operating condition.

5 After installation, when you operate welding work near the Joint, put nonflammable protective cover on the Joint.

2.Usual inspection------Not less than twice a year.
To find out abnormality earlier and avoid any accident, check the Joint, its operating condition, and installation.

6 When using it outdoors, protect from Ultra-violet rays.

3.Terminal inspection5 years after completion, check to find any defects which were not found by normal inspection, and confirm endurance of the Joint.

install it keeping enough distance from surrounding equipments especially sharp corners.
in order to avoid unnecessary pressure such as compression, extension, bending, or distortion.
In case welding heat might transfer to the Joint, remove it from the installation.

7 In case the fluid temperature is 60℃ or higher, do not put Joint cover.
8 Do not paint on the Joint.
9 When fixing the Joint to Pipe, use hexagonal bolts.

4.Emergency inspectionIn case of Earth quake, Fire, or Water flood, immediately inspect the Joint whether any abnormality occurred or not.
Also execute same inspection when any abnormality is found out by Usual inspection.

Insert the bolt from Joint Body side and fasten the nut with spring washer. Fasten all the bolts evenly.

10 The Joint will have reaction force due to inner pressure when operating.

Fix the pipes firmly especially near both ends of the Joint, so that the Joint can work in full performance.

11 If the pipes cannot be fixed firm enough, you can apply tie-rod.

In this case, allowable deflections might be reduced depending on sizes .

Temperature, Pressure and Deflection will vary the length of Joint Life.
After the Usable life, some improper condition like leakage may happen.
You are strongly required to carry out the following matters :1.Usual inspectionCheck the Joint at least once in a half year and confirm whether there is any abnormality.
2.Basis of ReplacementIf the following abnormality is found out, stop operation and replace the Joint immediately.
（1）
Fluid leakage（2）Damage/Flaw on Joint（3）Deformation on Joint（4）Remarkable corrosion on whole round of Flange（5）Movement exceeding allowable deflection of the Joint during operation12 If there are burrs, fliers, etc. on the piping or flange to be connected,there is a possibility of damaging theproducts. In the worst case there is a possibility of breakage of theproduct or leakage of the fluid, etc.
So, please remove burrs and rolled-up parts before piping.

13 Please use FF flange to the other piping side as much as possible to avoid damaging the seal face. When you use RF flangeunavoidably, please apply a hard gasket like the joint-seat.

27GuaranteeGuarantee period of this Joint is one year after delivery.
Please note that the following cases are out of guarantee :1.Accident and damage caused by incorrect installation, incorrect operation, repair,and reconstruction.
2.Accident and damage caused by natural disaster such as Fire or Earthquake.
3.Accident and damage caused by transportation after purchase or improper storage.
