In terms of the market, the current loss of pig iron enterprises is expanding, the willingness to increase is strong, some merchants have been increasing their offers, and the market has few low-price resources, but after the rise, the high price transaction is waver. In terms of cost, coke is expected to rise, iron ore is running strongly, raw material costs continue to increase, and the price support for pig iron is strong. In terms of demand, the cost performance of scrap steel is higher than that of pig iron, and the downstream casting enterprises have limited demand for pig iron, which is still mainly based on just-needed procurement. Overall, the cost of raw materials is still expected to increase, so it is expected that the market price of pig iron in East China will continue to run strongly next week. North China: This week, the price of pig iron in North China rose in a narrow range, now Linfen casting pig iron Z18 quoted 3550 yuan/ton, up 30 yuan/ton from last week, Wu 'an ductile iron Q10 quoted 3490 yuan/ton, up 40 yuan/ton from last week, Linfen ductile iron quoted 3520 yuan/ton, up 30 yuan/ton from last week, Tangshan steelmaking pig iron L8-10 quoted 3110 yuan/ton, up 20 yuan/ton from last week, the above are tax inclusive prices. In terms of the market, the black system is strongly shaken in the week, and the coke increase scope is expanded, which boosted the pig iron quotation slightly higher, but the downstream demand is limited, and the transaction is still concentrated in the low-price resources. At present, the cost of raw materials remains high in the short term, and pig iron prices are easy to rise and difficult to fall, so it is expected that the North China pig iron market will be stable and strong next week. Overall, the cost of raw materials is still expected to increase, and the price of pig iron in the northwest pig iron market continues to operate mainly in the short term. Since the increase in raw materials will lead to the increase in the price of BSEN877 Cast Iron Pipes, we will increase the price according to the market situation.

The bear pressure DN50-DN100 10 bar, DN150 -DN200 5bar, DN250-DN300 3bar.It's designed to over-clamp a standard EN 877 ductile iron or stainless steel mechanical coupling that provides 5 bar accidental static water pressure unrestrained and up to 10 bar fully restrained depending on the diameter and coupling type. The grip collar can be positioned during the first install at pressure sensitive points in the sanitary or rainwater system or can be retro-fitted at a later stage

Benefits of Cast Iron Cast iron is particularly well suited for all drainage systems as it offers many benefits, both for above and below ground installation, which include: Strength and durability - cast iron pipes are highly resistant to distortion caused by accident or vandalism. Long life - when correctly installed cast iron drainage systems will last the life of the building, whether domestic, public, industrial or commercial. Low maintenance - cast iron requires little ongoing maintenance, annual inspections are recommended but remedial action is rarely required. Design Capability - cast iron can meet the needs of restoration, refurbishment, conservation and heritage work as well as new, bespoke and unique designs. Sustainability - in addition to lasting the life of a building and requiring minimal maintenance, cast iron is also 100% recyclable and can therefore be used again after the building has gone. Cost effective - owing to its longevity, durability and low maintenance, coupled with its fire resistance and low noise operation, the cost benefits of cast iron are significant. Fire resistance and Safety - The melting point of cast iron is considerably higher than PVCu or PE and in the event of a fire will not emit toxic fumes or drop burning globules of material from one compartment to another.
