3. General Rules
3.0.1
SINOPEC standard SH3045-96 Steel Pipe Dimension Series for Petrochemical Enterprises has been issued and implemented to replace SHJ405-89. Considering the actual production and supply status of steel pipes and pipeline flange assemblies in China, it is difficult to fully implement the new standard for the time being. This standard is compiled basically in accordance with SH3405-96 with several revisions as follows:
- The outer diameters of steel pipes with DN350 ~ DN1000 are still compiled in accordance with the current regulations of our institute to facilitate matching and connecting with machinery industry flanges (JB/T81-94 ~ JB/T86-94).
- Considering that small outer diameter steel pipes may still be selected in the reconstruction design of old plants, the series of steel pipes with small outer diameters are supplemented in this standard, which are not recommended for selection.
- This standard lists SINOPEC standard SH3405-96 Steel Pipe Dimension Series for Petrochemical Enterprises. When adopting this series: for DN ≥ 350, supporting flanges, acessórios para tubos, fasteners and gaskets conforming to SH series must be used; for DN ≤ 300, either SH standard or other matching standards can be adopted.
- The steel pipe dimensions for DN ≤ 300 in Table 4.0.1 ~ Table 4.0.4 can also be matched with some foreign standards (por exemplo. ANSI standards). If pipes are purchased from abroad, their outer diameter and wall thickness shall comply with relevant foreign standards.
3.0.2
- For welded steel pipes with DN6 ~ DN150, select in accordance with GB/T3091-93 Galvanized Welded Steel Pipes for Low-pressure Fluid Transportation and GB/T3092-93 Welded Steel Pipes for Low-pressure Fluid Transportation.
- For welded steel pipes with DN150 ~ DN500, select in accordance with GB/T14980-94 Large-diameter Electric Welded Steel Pipes for Low-pressure Fluid Transportation.

4.0.6 Dimensions and theoretical weights of welded steel pipes are shown in Table 4.0.6.1, Mesa 4.0.6.2 and Table 4.0.6.3.
4.0.7 The steel pipe dimension series of SINOPEC standard SH3046 are shown in Appendix A.
4.0.8 Calculation Formula for Theoretical Weight per Meter of Steel Pipe
M = 0.02466 × t × (D – t)
Onde:
- M — Theoretical weight of steel pipe, kg/m
- t — Wall thickness of steel pipe, milímetros
- D — Outer diameter of steel pipe, milímetros
For austenitic stainless steel pipes, multiply the above calculated value by 1.015. For precise calculation, refer to Table 5 in GB/T14976-94 for the density of each type of austenitic steel.
