What will you react when you are paly the role of the end user, but find out that the steel pipes got corrosion after some time. When we buy steel pipes from the supplier, we expect steel pipes with good quality. Then we can put them into usage, such as transmit oil and natural gas, convey fluid liquid, etc. But if during some time’s usage, the pipes got corriosn, then what can we do when it comes to corrosion steel pipes? First, we should check why the pipes got corrosion. There are many reason that could cause corrosion to steel pipes. Pipe corrosion mainly comes from external corrosion and corrosive medium transported inside the pipe. Serious internal corrosion can happen on petroleum and sewage treatment transportation pipeline as there are lots of medium in these products. As we know why the steel pipes will get corrosion, we can know how to maintain and extend lifespan of steel pipe. Such as bare pipe is not suitable for wet condition. Different pipe coating is su...

When we use pipeline to transfer natural gas or oil for long distance conveyance, we always need to burry the pipeline underground. When steel pipes or pipe fittings are in contact with soil and wet condition, we must consider its external anti-corrosion ability to ensure a longer lifespan of the pipe. The 3 layers Polyethylene(3PE/3LPE) external coating perfectly solves this problem. Its first level is a high performance fusion bonded epoxy(FBE) layer, then comes an adhesive layer, and finally is an outer layer of high density polyethylene. The three layers external coating has excellent resistance to abrasion, wear, acid, alkali and cathodic disbonding, etc. 3LPE coated pipes consist of 3 layers for pipeline coating. First Layer: Fusion Bond Epoxy>100um consists of fusion bonded epoxy. This layer protection against corrosion and is fusion with the blasted steel surface. Second Layer :170～250um, is copolymer adhesive which has excellent chemical bonding to the internal...

Actually, steel pipe would have their lifespan so that we cannot hope that they can work for us once for good. They may die, means too rusty to put into use, whether SMLS steel pipe or   LSAW ,   SSAW ,   ERW steel pipe   if we don’t repair them or cure them when we figure out that they are ill(start to get cracks or rust). Rust would be one of the most common seen illness for steel pipe. First of all, we should figure out the etiological diagnosis for this ill. We know that steel would rust when they exposure to water, air, wet condition, etc. Under this situation, we should take different measures for different steel pipes when they transported to different environment for different purpose of usage. Then we should find the solution of cure the illness for them. The main use of wire brush and other tools on the polished steel surface, you can remove the loose or tilt the oxide skin, rust, welding slag and so on.

Seamless steel pipe, from its spell, we can tell that it doesn’t have any weld seam. So it can bear high pressure or high temperature working condition. Forming process for seamless steel pipe can be casting or cold drawing. Precision steel pipe need more advanced technology, so it just been applied in recent years. Also from the spelling, we can see that there will be much less tolerance for precision steel pipe, this includes OD tolerance, WT tolerance, roundness tolerance, length tolerance, weight tolerance, etc. Cold drawn precision steel pipe features: 1. Complicated cross section. 2. Accurate precision and good surface quality. 3. MOQ is much less than normal carbon steel pipes. 4. OD will be smaller. Generally speaking, for small OD with strict tolerance range, it would be better if we choose to go by precision steel pipe, especially for industrial steel pipe or steel pipes used for machines.
