1. Scope

This Standard covers the standardization of dimensions of welded and seamless wrought steel pipe for high or low temperatures and pressures. 

The word pipe is used, as distinguished from tube, to apply to tubular products of dimensions commonly use for pipeline and piping systems. Pipe NPS 12 (DN 300) and smaller have outside diameters numerically larger than their corresponding sizes. In contrast, the outside diameters of tubes are numerically identical to the size number for all sizes.

2. Size

The size of all pipe is identified by the nominal pipe size.The manufacture of pipe NPS 1⁄8 (DN 6) to NPS 12

(DN 300), inclusive, is based on a standardized outside diameter (OD). This OD was originally selected so that pipe with a standard OD and having a wall thickness that was typical of the period would have an inside diameter (ID) approximately equal to the nominal size. Although there is no such relation between the existing standard thickness — OD and nominal size — these nominal sizes and standard ODs continue in use as ‘‘standard.’’ The manufacture of pipe NPS 14 (DN 350) and larger proceeds on the basis of an OD corresponding to the nominal size.

Global steel demand turnaround to give HEG a growth spark

MUMBAI: HEG is probably at an inflection point. The manufacturer of graphite electrodes, a material used in electric arc steel furnaces, is set to benefit from a gradual turnaround in global steel demand. Increasing popularity of electric arc furnaces where the electrodes are used also augurs well for the company.

At present, 30% of steel globally is manufactured using electric arc furnace (EAF) method and the rest in basic oxygen furnace (BOF). But steel manufacturing is increasingly moving to the electric furnace method.

According to the management, EAF’s share in crude steel making is likely to grow exponentially to eventually overtake BOF. “In the first half of 2014, electric arc furnace production has gone up by more than 8% (globally) while total steel output has gone up by only 2.5%,” said R Rastogi, chief financial officer, HEG.

As a result, HEG’s June 2014 operating profit nearly increased 140% yoy. The primary reason for this is China, which accounts for more than half the global steel production and consumption. The share of EAF in Chinese steel production is just 9.5% – it is more than 50% in developed economies – but is increasing at a rapid pace due to rising inventory of scrap iron.

It is projected that a huge steel scrap reservoir in China is now being packed for use in the electric arc furnace sector. This trend in China is a “huge positive” for Indian electrode manufacturers, said Rastogi. BOF uses iron ore and coal while EAF uses scrap iron and power; the electrodes are used as conductors of electricity in the furnace. Globally, there are five players which together have 75% of the electrodes market.

Two of them – HEG and Graphite India – are Indian. With higher cost advantage over their global counterparts, the Indian players have been consistently gaining market share. The past few years had been bad for the electrodes industry, as global steel demand was low. The capacity utilisation of HEG has dropped to less than 70% because of this.

However, with the gradual but important shifts in the global economy, the worst seems to be over for the company. More than 75% of HEG’s revenue is from exports. Its India revenue too could grow with a pickup in the domestic steel demand. All these could lead to sharp earnings growth for HEG.

In the June quarter, its profit after tax was Rs 19 crore compared with a loss of Rs 9 crore in the previous year. “Improving earnings will help us reduce our debt by the end of FY15 and become debt free by FY16-end. This will improve all our ratios,” said Rastogi. HEG’s long-term debt at the end of FY14 was close to Rs 200 crore.

Among Indian electrode manufacturers, HEG’s shares are trading at 8.5 times its earnings for the trailing 12 months, compared with 13 times for Graphite India. HEG with a capacity of 80,000 million tonnes has a market capitalisation of Rs 1,000 crore while Graphite India with a capacity of 98,000 mt has a market value of Rs 2,160 crore. In the past six months, HEG’s stock has gained 22%, compared with 43% gain in Graphite India’s stocks.
