Foreword
This Standard was drafted as per the rules specified in GB/T 1.1-2009 Directives for
Standardization – Part 1. Structure and Drafting of Standards.
This Standard replaced SY/T 5324-1994 Prestressed Insulated Tubing; compared with
SY/T 5324-1994, this Standard has the major technical changes as follows besides
the editorial modifications.
--- Modified the product code (see 4.3 of this Edition; 4.3 of Edition 1994);
--- Deleted the specific numerical requirements for anti-repulsion and anti-extrusion
(see 5.1 of Edition 1994);
--- Modified the requirements for working conditions (see 5.1 of this Edition; 5.1 of
Edition 1994);
--- Modified the basis for determining the thermal insulation life (see 5.8 of this
Edition; 5.8 of Edition 1994);
--- Modified the technical requirements for product flatness (see 5.9 of this Edition;
5.9 of Edition 1994);
--- Modified the test program for apparent thermal conductivity (see 6.2.2 of this
Edition; 6.2.2 of Edition 1994);
--- Modified the size requirements for drift diameter gauge (see 6.5 of this Edition;
6.3 of Edition 1994);
--- Modified the requirements for product mark (see 8.1 of this Edition; 8.1 of Edition
1994);
--- Added the health, safety, environmental control requirements (see Clause 9).

Pre-Stress Insulated Tubing
1 Scope
This Standard specifies the product classification, technical requirements, test
methods, inspection rules, and mark, package, transportation, storage, and health,
safety, environmental control requirements for the pre-stress insulated tubing for
oilfield heat injection carrier.
The pre-stress insulated tubing uses viscous oil well to inject steam and produce. This
Standard is applicable to the production, inspection and acceptance rules of the pre-
stressed insulated tubing for steam injection.

5.2 Product insulating performance level
The product insulating performance level shall conform to the provisions of Table 1.
5.3 Material requirements
5.3.1 The tubing shall conform to the provisions of GB/T 19830. For the benefit of
sand washing and vacuum pumping, the surfaces of inner and outer tubes are required
to be exempted from rust.
5.3.2 The insulating material of aluminum foil shall meet the requirements of GB/T
3198.

requirements of GB/T 5117, GB/T 5118 and GB/T 8110.
5.4 Prestressed process requirements
5.4.1 According to the design requirements, separately calculate each tube’s
theoretical pre-elongation; the allowable deviation between the actual pre-elongation
and theoretical pre-elongation is ±0.5mm.
5.4.2 The heating method shall be adopted for the prestressed treatment process
rather than the mechanical method, the latter may damage the inner tube.
5.5 Processing requirements
5.5.1 After treatment, the outer surface of inner tube and inner surface of outer tube
shall be exempt from the rust and dirt; all can see is metal color; weld after drying and
assembling.
5.5.2 Perform welding process evaluation against the welding steel, welding material,
welding method and welding process; the process evaluation shall be performed as
per the provisions of NB/T 47014; and prepare the welding process procedures.
5.5.3 The width and height of weld seams shall be consistent; their appearance shall
be uniform and full; smoothly transit to the base metal; the spatter around the weld
seam shall be cleaned up.
