Summary
This standard is applicable to the alloy pipe standard with good corrosion resistance for conveying gas, water and oil in the oil and natural gas industry. The specification code is the pipe's nominal specification (NPS). The pipe specification limits (or specification ranges) given in this standard are all of the outside diameter specifications, except that they are nominal values. These outer diameter specification limits and ranges also apply to the corresponding nominal specifications. The main product is the grooved pipe. If you need to straighten or other special tube end flat tube, should be negotiated by the purchaser and manufacturer. This standard includes the nominal specification lin ~ 42in. The steel grades covered by this standard are: LC30-1812, LC52-1200, LC65-2205
