Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO
member bodies). The work of preparing International Standards is normally carried out through ISO technical
committees. Each member body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, governmental and non-governmental, in
liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
The main task of technical committees is to prepare International Standards. Draft International Standards adopted
by the technical committees are circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 13533 was prepared by Technical Committee ISO/TC 67, Materials, equipment and offshore structures for
petroleum and natural gas industries, Subcommittee SC 4, Drilling and production equipment.
Annexes A and B form a normative part of this International Standard. Annexes C, D, E, F, G and H are for
information only.
ISO 13533:2001(E)
Introduction
This International Standard is based on API Specification 16A, second edition, 1 June 1998.
This International Standard is intended to provide for the availability of safe and functionally interchangeable drill-
through equipment utilized in the petroleum and natural gas industry.
Users of this International Standard should be aware that further or differing requirements may be needed for
individual applications. This International Standard is not intended to inhibit a vendor from offering, or the purchaser
from accepting, alternative equipment or engineering solutions for the individual application. This may be
particularly applicable where there is innovative or developing technology. Where an alternative is offered, the
vendor should identify any variations from this International Standard and provide details.
For the convenience of users of this International Standard, annex H provides a list of those normative International
Standards cited in clause 2 with national or regional standards which have been found mutually applicable in the
context of the requirements in the text. The user may optionally apply the national or regional standard in the
context of the requirement for which the International Standard is cited.

5.3.1.2 API type 6B flange connections
Type 6B flange connections are of the ring joint type and are not designed for face-to-face make-up. The
connection make-up bolting force reacts on the metallic gasket. The type 6B flange shall be of the through-bolted
or studded design.
Dimensions for type 6B integral flanges shall conform to ISO 10423.

5.3.1.3 API type 6BX flange connections
Type 6BX flanges are of the ring joint type and are designed with a raised face. Depending on tolerances, the
connection make-up bolting force may react on the raised face of the flange when the gasket has been properly
seated. This support prevents damage to the flange or gasket from excessive bolt torque. Therefore, one of the
flanges in a 6BX connection shall have a raised face. The type 6BX flange shall be of the through-bolted or
studded design.
Dimensions for type 6BX integral flanges shall conform to ISO 10423.
Dimensions for all ring grooves shall conform to ISO 10423.
