Equivalency Certificate

SU 5725 (Ren. 3)

CONDITIONS

(b) the cylinders are used for hydrocarbon well sampling services only;

(c) the cylinders contain only hydrocarbon gas mixture, compressed, n.o.s., Class 2.1, UN1964;

(d) a pressure relief device is not required. However, when subjected to the fire test, the cylinder vents due to seal failure and does not rupture;

(e) after each fill, each cylinder is disassembled, visually inspected and cleaned, and the seals are replaced before the cylinder is re-assembled, by the certificate holder, in accordance with Baker Hughes Canada procedure number 190058‑855 or 199890-855;

(f) for transport, each cylinder is equipped with shipping adapters and a threaded steel protective cover at the manual-valve end;

(g) each cylinder is transported in a strong outer packaging;

Manufacture and Requalification

(h) the cylinders are manufactured by Dearborn Precision Tubular Products Inc., Fryeburg, Maine, U.S.A. and Alpa Precision Metal Works in Houston, Texas, U.S.A., in accordance with the procedures, specifications and drawing number 190058-000 or 199890-000, filed by the certificate holder with Transport Canada's Dangerous Goods Branch;

(i) subject to conditions (j) to (u), the cylinders are in compliance with the requirements applicable to Specification TC-3AAM set out in CSA Standard B339-08, "Cylinders, spheres, and tubes for the transportation of dangerous goods", March 2008, and cited in the rest of the certificate as CSA B339-08;

(j) the cylinders are hydrocarbon well sampling cylinders, consisting of seamless tubing threaded at both ends and capped with machined heads. Each cylinder is equipped with a floating piston designed to separate the hydrocarbon-well-sample end from the pressurization end;


Equivalency Certificate

SU 5725 (Ren. 3)

CONDITIONS

(k) the cylinders have a service pressure of 138.0 MPa, a maximum water capacity of 850 mL and an outside diameter of 47.8 mm;

(l) the cylinder components are manufactured from MP35N alloy as specified in National Association of Corrosion Engineers (NACE) Standard MR0175, "Sulfide Stress Cracking Resistant metallic Materials for Oilfield Equipment", published in 2001;

(m) the cylinders have a minimum wall thickness of 5.5 mm and the maximum wall stress of 483 MPa, specified in Clause 6.3.1(a)(i) of CSA B339-08, does not apply;

(n) heat treatment of the completed cylinder is not required;

(o) a tensile test is not required for on a completed cylinder, provided that it is performed on a sample taken from each heat lot of MP35N bar material for each lot of 200 cylinders or less, and the minimum tensile strength is 1310 MPa, the minimum yield strength is 1241 MPa, and the elongation is 10% for a type D specimen;

(p) a flattening test is not required;

(q) in addition to the hydrostatic test, additional pressure testing is performed on each cylinder assembly in accordance with Baker Hughes Canada procedure number 164127-610 or 199890-610;

(r) the Transport Canada mark, the specification designation and the service pressure marked on each cylinder is:

TC-SU-5725

followed by the service pressure expressed in bar;

(s) the markings are engraved or laser-marked in low-stress areas near the ends of the cylinder in accordance with Baker Hughes Canada drawing 190056-000 or F199569000 and Baker Atlas procedure 059969-000 and the markings are at least 3.3 mm in height;


Equivalency Certificate

SU 5725 (Ren. 3)

CONDITIONS

(t) despite Clause 4.13.5 of CSA B339-08, for qualification of a new design, cylinders are hydrostatically tested to at least 2.25 times the service pressure and do not burst, but leak due to seal failures at the end closures;

(u) despite Clause 24.2.1.5 of CSA B339-08, each cylinder is requalified by the certificate holder, in accordance with the requirements for Specification TC-3AAM in Clause 24 of CSA-B339-08 and the additional pressure testing requirements specified in Baker Hughes Canada procedure number 164127-610 or 199890-610. The requalification period is five (5) years;

(v) the certificate holder reports any incident involving loss of contents or failure of the cylinders to the Director, Regulatory Affairs Branch, Transport Dangerous Goods Directorate, Transport Canada.

NOTE

Under Canadian Law, a foreign manufacturer of non-specification means of containment cannot be charged with an offence under the Transportation of Dangerous Goods Act, 1992 for failure to comply with the conditions of an Equivalency Certificate. However, certain remedies under the Act are available to Transport Canada in this eventuality.

These include:

1. detention of dangerous goods and consequently the means of containment containing them (subsection 17(1));

2. detention of the means of containment whether full or empty (subsection 17(1));

3. directions not to import the means of containment or to return them to origin (subsection 17(3));

4. inspectors' directions (section 19);

5. directions to importers of the means of containment to issue notices of defective construction or recall (subsection 9(2)); and

6. revocation of the certificate, thereby making any use of the means of containment an offence (subsection 31(6)).

If none of the foregoing is adequate, Protective Directions may be issued to prohibit or to control the use of the means of containment (section 32).
