Why is CTS tube your best choice among its peers?

First of all, CTS has had very good relationships with a lot of famous Chinese factories for more than 10 years. Almost all Chinese famous factories that you can name of have long term cooperation with us. For example, TPCO, HYST, BAO STEEL, ANHUI TIANDA, JIANGYING SEAMLESS, JIULI, and WUJIN, etc.

Because of our good relationships, we can get lower price from them, and make more efficient communication with them.

Furthermore, CTS supplies a big range of metal tubes, including carbon steel tubes and pipes, stainless tubes and pipes, alloy steel tubes and pipes, copper & brass tubes and pipes, titanium alloy tubes and pipes, fin tubes, U bending tubes, and bearing tubes, etc.

CTS is your best choice of one-stop solution in purchasing seamless carbon steel tubes.

Normally, it seems like each kind of metal tubes is produced by a different factory. Due to that, if you need to purchase more than one kind of them, contacting with so many different factories and doing repeat jobs time after time may become your big headache, not to mention the difficulty of arranging the loading and delivery of them together.

Therefore, to choose CTS to get the one-stop purchasing solution service is your best decision. CTS will monitor the whole process from ordering to delivery, so that everything will be under control as much as possible.

Our competitiveness in seamless carbon steel tubes.

One of our most competitive products is heat exchanger tube, ASTM A179 standard, cold drawn. It is not only used for heat exchangers, but also in condensers and other similar heat transferring devices.

Another most competitive product is high pressure boiler tube. Standards include ASTM A192, ASTM A210 and DIN17175. For ASTM A210 standard, we can provide GR. A1 and GR. C material. For DIN17175 standard, we can provide ST35.8 material.

They could also be used for super-heaters and other high pressure services.
