What Should We Pay Attention To In Transporting SMLS Pipes?

Seamless steel pipes are widely used as conduits for fluid delivery and have a hollow section in transportation of oil, natural gas, gas, water and some solid material pipelines. Compared with round steel and other solid steel, the steel pipe has the same bending, torsion strength, and lighter weight. It is a kind of economic steel section. It is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automobile drive shafts, bicycle frames and steel scaffoldings used in construction. It can improve the material utilization rate, simplify the manufacturing process, save materials and processing hours, such as rolling bearing rings, jack sleeves, which have been widely used in steel pipes.
 
Common resource materials in stock are 10#, 20#, 35#, 45#, 16Mn, 27SiMn, 40Cr, 12Cr1MoV, 10CrMo910, 15CrMo, 35CrMo, 45Mn2, etc.

Delivery status
It refers to the state of final plastic deformation or final heat treatment of the delivered product. Generally, the delivered status without heat treatment was called hot rolling or cold drawing (rolling) state or manufacturing state. The delivery status after heat treatment was called the heat treatment state. According to the type of heat treatment, it was called normalization, quenching, solution, annealing state. When you are ordering, the delivery status shall be indicated in the contract. 

Weight delivery status
Actual weight - at the time of delivery, the product weight is delivered according to the weighed weight.
 
Theoretical weight - in delivery, the product weight is calculated according to the nominal size of the steel.

Applications
1. In Construction: underground pipeline transportation, groundwater extraction during building construction, boiler hot water transportation, etc.
2. In mechanical processing, bearing sleeves, processing machinery accessories, etc.
3. In the electrical industry: gas transmission, water generates electricity in fluid pipes.
4. Anti-static pipes in wind power plants, etc.

Chinese standards of current seamless steel pipes
1. Current standards of seamless steel pipes: a total of 47 items (basic 2 items and other 45 items) including 25 items in GB and 3 items and 19 special purposes in HB.
2. Common standards of seamless steel pipes: 
① GB/T 2102-2006 Acceptance, packing, marking and quality certificate of steel pipes.
② GB/T17395-2008 Dimensions, shapes, weight and allowable deviation of seamless steel pipes.
③ GB/T5310-2008 Seamless steel pipes for high-pressure boilers.
④ GB/T6479-2000 Seamless steel pipes for high-pressure fertilizer equipment.
⑤ GB/T18248-2008 Seamless steel pipes for gas cylinders.
 
It is said that more and more industrial enterprises will use seamless steel pipes. Some enterprises also found that in the process of using this kind of pipe, perhaps a situation of corrosion will appear on some seamless steel pipes. As for the corrosion of this situation, the relevant person in charge of the enterprise also wants to know why there will be such a situation.
 
If there is corrosion in transportation, how to deal with it is critical. We also know that most enterprises now use the seamless steel pipe, which is composed of two important parts: the transport sensor and transport converter which has the transport of the original and electrode coil and shell, etc.

Industry professionals said that the transmission signal was very weak in the process of transportation of seamless steel pipes. Therefore, we must ensure that the key parts of the pipe grounding must be kept clear. The liquid must also be transported with conductivity of liquid. More ferromagnetic substances or bubbles should not be contained in it.
