Throughout draft 26 occurrences General This is a general comment with an alternate

suggested change, in regard to four other comments

correcting use of "end outlet connections:" There is

very inconsistent usage in the draft of the combined

use of the terms "end connection" and "outlet

connnection." In all but two usages in 16C, "end

connection" alone is sufficient and unambiguous.

The exceptions are 10.7.9 and 10.14.2, where "outlet

connection" is used to differentiate one end

connection from the another (inlet connection) for

drilling chokes and for buffer chambers.

Use "end connection" in place of "end and

outlet connection," "end or outlet connection,"

"end outlet connection," "end connection and

outlet connection," "end connection or outlet

connection," and "outlet connection,"

everywhere in the standard except in 10.7.9.

3.1.4, 3.1.30 Editorial Articulated choke and kill lines and flexible choke

and kill lines are in the Scope, but are not defined.

This is problematic because API 53 has definitions

and requirements for "choke/kill line" that conflict with

16C. In 16C, flexible, or articulated choke/kill lines

consist of piping and connections only. In Std 53,

"kill line" requirements include valves and pressure

gauges.

(1) Change title of 3.1.4 to list both terms:

"articulated line" and "articulated choke and kill

line." (2) Change title of 3.1.30 to list both

terms: "flexible line" and "flexible choke and kill

line." For an example of a definition with two

terms in the title see 3.1.39.

3.1.55 Editorial (1) The term used in ten places throughout 16C is

"rigid piping" and "rigid choke and kill lines"

and kill lines are listed in Scope and in the

should be unambiguous.The NOTE in 3.1.55 states

"Rigid pipe includes choke and kill lines," but

4.1.4 Technical This section is techncially redundant to 4.1.4.2. The

two are also inconsistent. First, 4.1.4.1 deals with

flange and hub end outlet connections...while 4.1.4.2

deals with end AND outlet connections.

And there is "no good English" in 4.1.4.1...Design

of... shall be design in accordance..."?? Also, since

design requirements are integral to Spec 16A and

6A, as are the manufacturing requirements, to have

two separate requirements for design and

manufacture (with respect to 6A/16A) is redundant.

Combine 4.1.4.1 and 4.1.4.2 into:

Flange and hub end connections shall be

7.5.4.1 General The phrase "prior to shipment from the

manufacturer's facility" is neither a technical

requirement nor a standardization requirement, it is a

commercial restraint that does not belong in a

product specification. The manufacturer may have

reason to perform hydrostatic testing at a

subcontractor or corporate sister facility. If the

manufacturer has documented procedures and off-

site personnel to control the test process and final

acceptance, the product spec should not require that

the equipment be shipped back to the OEM facility

before shiipment to the customer. E.g., if a fully

assembled choke manifold is too large for road

shipment, it may be shipped to a dockside facility in

sub-sections, fully assembled and tested there, and

shipped by water to the purchaser directly from the

remote facility. This is a logistics exercise only and

does not compromise the product, the

manufacturer's quality management system, or any

institution's use of the word "manufacturer."

Replace "prior to shipment from the

manufacturer's facility" with "prior to final

acceptance."

7.5.4.1 General The phrase "prior to shipment from the

manufacturer's facility" is neither a technical

requirement nor a standardization requirement, it is a

commercial restraint that does not belong in a

product specification. The manufacturer may have

reason to perform hydrostatic testing at a

subcontractor or corporate sister facility. If the

manufacturer has documented procedures and off-

site personnel to control the test process and final

acceptance, the product spec should not require that

the equipment be shipped back to the OEM facility

before shiipment to the customer. E.g., if a fully

assembled choke manifold is too large for road

shipment, it may be shipped to a dockside facility in

sub-sections, fully assembled and tested there, and

shipped by water to the purchaser directly from the

remote facility. This is a logistics exercise only and

does not compromise the product, the

manufacturer's quality management system, or any

institution's use of the word "manufacturer."

Replace "prior to shipment from the

manufacturer's facility" with "prior to final

acceptance."

7.5.4.1 1st para Technical The sentence that reads "Hydrostatic test pressure

shall not be applied as a differential pressure across

internal…" is a limiting sentence. Though chokes are

not required to isolate, we should not prohibit this

test with a SHALL NOT. From a field perspective I

am more likely to purchase a choke that has this

capability. However, given that wording we prohibit

the OEM from proving this.

Reword to clarify that the choke does not need

to be tested as an isolation device but do not

prohibit this test.

A.12.3.1.3 Technical Verification testing qualifies the size and pressure

proposed text: 1) is inconsistent with other flexible

verification tests (all others qualify size tested plus

equal or smaller size and pressure) in the standard,

2) is not a representative test – allowing qualification

of the next ID size up does not take into account the

larger surface area and therefore increased diffusion

that will occur during verification testing
