China's Principal Ports
Show 26 Percent Increase
In Container Cargo
Officials said recently that Chi- na's principal ports handled the equivalent of 1.5 million 20-foot containers (TEUs) last year, the most since it began box container services.
This is nearly 26 percent higher than the ports handled in 1989, according to the Ministry of Com- munications.
Though the precise figure of over- all capacity is not known, the minis- try said there are 74,000 container berths. China constantly upgrades ports and adds container facilities.
In the last decade, 20 container berths were added, with aggregate capacity of 1.3 million TEUs. Along with expansion of intermodal and interior land transport, more are scheduled for the five-year plan that recently began.
Makes Tube Fitting
A tool for pre-swaging Swagelok tube fitting ferrules prior to actual fitting pull up is available from
Swagelok Co., Solon, Ohio.
The pre-swaging tool is especially useful with closely spaced connec- tions, difficult-to-reach installa- tions, and other applications where wrenches are difficult to use.
According to the company, pre- swaging ferrules with the pre-swag- ing tool is quick and easy. The installer inserts the tubing through the nut and ferrules and bottoms the tubing in the pre-swaging tool.
The nut is tightened 1-1/4 turns (3/ 4 turn for 1/16-inch, 11/8-inch and 3/16-inch size tube fittings), the nut is loosened, and the tubing with the pre-swaged ferrules is removed from the pre-swaging tool. The installer completes the assembly by following the normal Swagelok tube fittings retightening instructions.
The pre-swaging tool is made of heat-treated tool steel and is avail- able for Swagelok tube fitting sizes 1/6-inch through 1/2-inch.
