Corrosion of spiral steel pipe manufacturing necessities according to the national standards for production, the unique processing technique in accordance with the usual is unique, but are in step with national manufacturing standards, and to adjust to and implement.
1, engine oil properties the oil and gas with three layers of polyethylene anticorrosion insulation steel pipe, steel pipe. Demand in the technique of transportation of pure gas, used three layer, or layer of polyethylene insulation pipe, software of steel tube in this way can make sure that the transportation security and has been efficient in, assure the steel pipe from corrosion or damage. The anti-corrosion insulation pipe is execute customary sy/din30670 t0413-2002, when manufacturing is in accordance with the standard manufacturing, guarantee the smooth progress of work, assure the standard of the product.
Eyes anti-corrosion steel pipe processing varieties has the next kinds of insulation, demand set and alternative, on the idea of the distinctive circumstances under introduce you the anti-corrosion insulation pipe processing varieties: by way of general excess capability is probably the most typical thick wall steel pipe, reminiscence 2009 thick-walled steel pipe excess capacity up to a hundred million tons, nonetheless, steel funding continues so as to add new capacity proceed rising. Whereas the thick wall steel pipe merchandise and inorganic salt trade equivalent to funding development is much larger than the trade average improve, methanol and other coal chemical projects “blossom”. As well as, in response to fa monetary fund (imf) forecasts, 2009-2012 years of world shipbuilding capacity is one engine oil properties hundred million ton.
From the thick wall spiral steel pipe product construction, excess production capacity considerably mid-range’s sphere. At present, domestic in addition to high-finish superior processing and mineral merchandise, the overwhelming majority of graphic steel smelting capacity, yield was first on the planet
2, oil with fbe (single fusion bonded epoxy powder anticorrosive) anticorrosive spiral steel pipe, and home most vivid thick wall steel tube metal smelting extreme overcapacity.
3, water provide pipeline to cement mortar lining steel pipe anticorrosion. Demand for application in water provide pipeline cement mortar conveying the anti-corrosion insulation pipe, tube of water and sediment within the steel pipe has been efficient barriers, reduce the transmission of the resistance. Implementation of requirements for the production of the anticorrosive spiral steel pipe is cecs10:89.
Debated broaden home engineering equipment enterprise manufacturing line, the industry’s prime six firms have been prolonged to the whole collection of merchandise, which tended to low stage, low costs, business technical level has not improved. Shipbuilding capacity is generally type making extreme energy growth, high technology, excessive added worth product growth power isn’t robust.
The anti-corrosion spiral steel pipe. Fancy transport material may have original materials of steel pipe in transport, to make sure the safety and reliability of transport materials. Fbe anti-corrosion insulation pipe and a couple of fbe anti-corrosion insulation pipe has consistent manufacturing commonplace, production and processing customary sy/t0315-97, sy/t0315-2005.
4, epoxy coal tar anti-corrosion glass cloth spiral steel pipe. The anti-corrosion insulation pipe is very important and effective corrosion safety of asphalt, stopping the hurt of asphalt was carried out on the steel pipe must. Manufacturing standard: sy/t0447 gb50268-97-97.
