Zhejiang Kingland puts spiral pipe plant into operation

As a result, the welding machines can attain an efficiency rate of over 90 per cent. Another benefit is the reduced transfer of heat into the pipe. For this purpose, the process parameters are adapted for each individual welding wire, in order to prevent unnecessary heat being transferred into the pipe material. This is particularly important for high-strength steels. Zhejiang Kingland uses its offline spiral pipe welding plant to produce pipes to API 5-L PS2 standard, with an outside diameter of 508 to 1,626mm (20" to 64"),

ZHEJIANG Kingland Pipe Industry, based inHuzhouCity, ZhejiangProvince, China, has successfully commissioned a spiral pipe plant supplied by PWS. With its use of ‘PERFECT ® arc’, the plant meets Ecoplants criteria in terms of sustainability, and offers energy savings of up to 30 per cent, along with increased productivity. The plant consists of a spiral pipe forming and tack-welding machine for forming and pre-welding hot rolled steel strip, and three downstream offline finish-welding stands. It has a capacity of 200,000 tons per year, but can be extended by a fourth finish-welding stand to increase capacity to 260,000 tons. The newly developed Perfect arc welding current sources are used for the welding machinery. No transformers are required – the systems are operated using IGBT (insulated-gate bipolar transistor) power electronics, with the welding current completely digitally controlled.

wall thicknesses of 6.35 to 25.4mm (¼" to 1"), and lengths of 8 to 12.5m. The plant processes high-strength steels up to API grade X100.

T&H Lemont appoints program and marketing manager

Mr Chen earned a Masters Degree from Sun Yat-sen University in Guangzhou, China, and is an experienced project manager having successfully completed course work in the discipline of modern project management from the Johnson Control Program Manager University in Shanghai, China.
