Steel Pipe Indication

Pipe description ++++++++++++++++++++++++++++++ Pipes are described by nominal size (e.g. 125A), which refers to and approximately matches inside diameter in mm. Pipe wall thickness is described by the pipe schedule (e.g. Schedule-40 or Schedule-80). Same A-size pipes in different schedules will have the same Outside Diameter (O.D.) but different wall thickness (Schedule-80 is thicker than Schedule-40). Schedules 5, 10, 20, 30, 40, 60, 80, 100, 120, 140, 160 JIS standard for steel ++++++++++++++++++++++++++++++ SUS 430 Stainless steel 18 Chrome SUS 304 Stainless steel 18 Chrome & 8 Nickel Example of steel pipe marking ++++++++++++++++++++++++++++++ JIS pipe categories +++++++++++++++++++++++++++++++ SGP Steel Gas Piping - Carbon Steel Pipe for Ordinary Piping STGP Steel Tube Piping General - Carbon Steel Pipe for pressure services STS Steel Tube Special - Carbon Steel Pipe for high pressure services STPT Steel Tube Piping Temperature - Carbon Steel Pipe for high temperature services STPL Steel Tube Piping Low - Carbon Steel Pipe for low temperature services Dimensions of Welded and Seamless Steel Pipe (ANSI/ASME B36.10M)

Heinrich Law to floor the DEVIL

The company I sailed for - Nippon Yusen Kabushiki Kaisha (NYK) - implements some theoretical background in its safety programmes. Looking for the effective ideas on how to increase the level of safety in order to prevent maritime accidents and to ensure safe vessel operations, NYK runs the DEVIL Hunting (or Near Miss 3,000) campaign, which is a process NYK uses to identify Dangerous Events and Irregular Looks. The DEVIL Hunting campaign bases on the Heinrich's Law.



Heinrich's Law says that behind every serious accident there are 29 minor accidents and 300 near miss experiences. NYK goes further in identifying the basement of the pyramid which expends to 3000 unsafe conditions or unsafe acts. These unsafe conditions or unsafe acts are called Devils. As seen on the figure by identifying and preventing 3000 Devils company may save 29 minor and 1 major accidents.

Why does NYK do it? Reasons are:
1/ Identification of the Devils lies on the staff-in-the-field shoulders. That means it is an effective incentive to teach the staff of augmented self-care not only for an individual but for a working group, be further safe conciousness in unfamiliar conditions and preferring safe practices as the extras to the achieving the otherwise expected performance levels.
2/ In case the theory works, then it adds to saving a lot of money as each maritime accident costs a lot. I am not talking about major maritime disasters about the measurable parameter of downtime. If the statistics is true then the below figure proves saving for the company.
3/ It adds positively to the image of such a world class logistics and megacarrier provider as NYK.


So why not, even if many experts say Heinrich Law is too much controversial? NYK gets result from the mainstream idea. Brilliant branding of the campaign to teach and incite the employees. Get on board the boat!

No changes to Volvo’s supply routes until new ownership confirmed

There will be no changes to Volvo Cars’ transit routes while the future of the Ford-owned, Swedish-based carmaker is still uncertain, a Volvo source confirmed.

There will be no changes to Volvo Cars’ transit routes while the future of the Ford-owned, Swedish-based carmaker is still uncertain, a Volvo source confirmed.

Oleksii Chepok, deputy director dry bulk terminal at TransInvestService Ltd. in the Ukraine told this newsletter that the governor of the Odessa region of the Ukraine, Mr. Mykolai Serdiuk, held a press conference following his return from the recent CPMR Baltic Sea Commission conference in Gothenburg. Mr. Serdiuk reported that he had met with Volvo representatives at the conference and that the car company had plans to transit cars destined for Russia via one of the ports in the Odessa region. According to Mr. Serdiuk, there were also plans to build an assembly plant nearby and to offer long term leasing of Volvo equipment to local port operators.

Ford has nominated the Chinese company Zhejiang Geely Holding Group as the preferred bidder for its Volvo Cars nameplate. Until due diligence is complete and funding for the bid secured, no new logistics initiatives are expected.
