Sandvik has opened a state-of-the-art coiled tubing line for premium grades of seamless stainless-steel products in smaller dimensions at its Zhenjiang tube mill near Shanghai, China. The commitment to produce longer lengths of weld-free coiled tubing locally will allow customers in the Asia Pacific region to receive deliveries within 28 days, instead of waiting four to six months for longer-length reels to arrive from abroad.
“The new coiled tube offering is a further step in our commitment to boost the competitiveness of customers in China and throughout the Asia Pacific region,” said Satish Sharath, business unit president Sandvik Tube APAC. “We’ve seen a rising demand on projects within chemical processing, oil and gas, alternative energy, and other industries for urgent local supplies of coiled tubing. The compact reels, ease of transport, and ability to precisely cut lengths in challenging situations allow customers to work fast and efficiently, with fewer connectors and zero risk of system leakage.”
Initially, the focus will be on Sandvik 3R60™ (ASTM TP 316/316L) tubing – an austenitic chromium-nickel steel with a minimum of 2.6 percent molybdenum and low carbon content – in outer diameters from 6.0 to 14 mm. The coiled tube is supplied as level-wound on plastic-wrapped wooden reels in standard (55-260 m) or longer lengths (135 – 611 m), or as bulk coil, strapped into boxes. The new range complements Sandvik’s current offering of six-meter straight lengths of hydraulic and instrumentation tubing, which are already available in the widest range of sizes and grades on the market.
“At first glance, most tubing looks pretty much the same,” said Glenn Darley, regional sales and marketing director in China. “But numerous tests show that Sandvik truly sets a standard within the various product and grade standards, consistently delivering at the highest levels on key performance criteria such as ovality, corrosion resistance, surface smoothness, and tight tolerances. This – and our deep materials expertise – matters a great deal to end users who often discover the hard way that inferior local grades can lead to system leakage, unplanned maintenance or – even worse – a plant shutdown.”
According to Darley, the 28-day delivery promise means, in effect, that Sandvik coiled tubing is now “closer than you think.” In addition to Sandvik 3R60™ (ASTM TP 316/316L), the company will supply other grades of high-alloy and duplex tube products in a wide range of dimensions, however, they will be handled on a case-by-case basis, by country, and may be subject to slightly different delivery times than the 28-day guarantee now being offered for standard grades.
“Our aim is to better serve customers in the Asia-Pacific region,” said Paul Tsai, production unit general manager at the Zhenjiang Mill. “The new offering combines advanced production technology and unique manufacturing know-how with extensive technical support.” The mill
he oversees, located 250 kilometers northwest of Shanghai, produces straight and U-bent tube for heat exchangers and hydraulic and instrumentation tubing in austenitic and duplex stainless steels as well as high-alloy austenitic stainless steels and nickel alloys.
