RISK ASSESSMENT AND CLASSIFICATION
All flanged joints shall be categorized and managed through the leakage risk assessment process.
The risk assessment criteria shall be based on assessing media, temperature, and pressure etc.
condition, and be rated according to the leak and loss potential, the risk of human injury, the
environmental impact and system stabilization operating, among others.
Each level of risk for the service condition of flanged joints is categorized as the following:
4.1 High-Risk: Joints for critical service lines
Flanges determined to pose the greatest risk to personnel, environment, and plant in the event of
the leak will be classified as the joints for critical service.
Critical service lines are defined and identified as;
a. Joints in Category M Fluid Service (ASME B31.3).
b. Joints in cryogenic services.
c. Joints the operating at temperatures 350°C and above.
d. Joints subject to high pressure (Rating Classes
900# and bolt size 2” & larger ).
e. All standard flanges inclusive of flanges with the size of NPS 60 above.
f.
Tie-in flange joints (that not subject to pressure test or leak test before).
g. Joints with a history of frequent leaks (during pre-commissioning) based on Licensor
and Operation’s recommendations.
4.2 Medium-Risk: Joints for normal service lines
The term “fluid service” is defined as per the Chapter I para.300.2 and Appendix M of
ASME B31.3 provides guidance in classifying the fluid service category. As paragraph 5.1

specified, some of the lines had classified as critical service lines. Therefore, the other
lines are specified as the joint for normal fluid service, except Category D fluid service.
4.3 Low-Risk: Joints for utility service lines
The lines are classified as Category D fluid service or nonflammable or nontoxic etc., are
specified as the joints for utility service lines.
5 CRITERIA FOR BOLT TORQUE
5.1 Tightening Method
a. For high-risk joints, the qualified technicians shall be sufficient, providing and using bolt
torque in bolting might be required, and project inspection shall witness all joints of
critical service lines.
b. For medium risk joints, the qualified technicians shall be sufficient, providing and using
manual torque wrench in bolting could be accepted.
c. For low risk joints, using manual wrench, tight only.
