1. GENERAL
1.1 Scope
This specification together with the requisitions, purchase order/inquiry, attached drawings,
and data sheets covers the requirements to be met by Vendor in the design, fabrication"
inspection, testing, and supply of shell and tube heat exchangers.
This specification shall not be apply to such pressure vessels and heat exchangers that are
normally designed under the manufacturer's standard; i.e. pressure vessels which belong to
packaged unit, pressure vessels which are attached to turbines, engines, pumps, compressors
and other mechanical equipment, etc. However, the manufacturer's specifications are Subject
to Owner's approval.
1.2 Specific Job Requirements
Specific Job Requirements which are attached to this specification cover modifications to this
specification, Customer's special or local requirements as well as specific job data pertinent to
this specification.
Where Specific Job Requirements are in contradiction to this specification, Specific Job
Requirements shall govern.
1.3 Codes and Standards
1.3.1 The following Codes and Standards shall be applied as the minimum requirement
For pressure parts design : ASME Section VIII Div.1 & 2, 2010 Edition
For shell & tube heat exchanger : TEMA Class B-9th Edition (2007)
For material of pressure part : ASTM, AWS, JIS, DIN
Manufacturer's Country of Origin with OWNER's approval
For flange : ASME B16.5 (Refer to Table U-3 of ASME Section
VIII Div. 1)
For screw thread of bolt and nut : ASME B 1.1 for ASME Flanges
IS0-261 for others
For welding qualification : ASME sect IX, 2010 EDITION
For expansion joint : Tube sheet by ASME Expansion joint by EJMA
or
Tube sheet by TEMA Expansion joint by TEMA
1.3.2 It shall be the responsibility of Vendor that all aspects of the design, fabrication,
inspection and testing conform to the requirements of the specified codes and
standards, and legal requirements.
1.3.3 Where there are conflicts between Purchaser's drawings/ specifications and the
specified codes/standards or legal requirements, such conflicts shall be promptly
referred to Purchaser.
1.3.4 Combined stress calculation for vertical vessels shall be carried out in accordance with
JPI-7R-35-2004."Design of Vertical Vessels Supported by Skirt" or BS 5500, against
wind and earthquake shall be referred to Basic Engineering Design Data. Wind load
shall be calculated in accordance with Sect 3.9 of Engineering Specification for Design
Loadings UBE-A-100.
