API 5L X70 pipe is a premium grade piping material in API 5L standard specifications. Also called L485 pipe, as it’s yield strength minimum in 485 Mpa (70,300 psi). API 5L X70 covers manufacturing types in seamless and welded (ERW, SAW) types, both applied for oil and gas transmissions.
Q345B low alloy seamless steel pipe has many classification methods. According to the manufacturing process, there are: hot-rolled seamless steel pipe and cold-rolled seamless steel pipe. According to the use, there are: seamless steel pipe for general structure, seamless steel pipe for transporting fluids.
According to different production methods, it can be divided into hot-rolled pipes, cold-rolled pipes, cold-drawn pipes, extruded pipes, etc.
1.1. Hot-rolled P91 alloy pipes are generally produced on automatic pipe rolling units. The solid tube blank is inspected and surface defects are removed, cut into the required length, centered on the perforated end of the tube blank, and then sent to the heating furnace for heating and piercing on the punching machine. It continues to rotate and advance during piercing holes. Under the influence of the rollers and the end, the tube blank is hollow gradually, which is called gross pipe. Then it is sent to the automatic pipe rolling machine to continue rolling. Finally, the wall thickness is evened by the leveling machine, and the diameter is determined by the sizing machine to meet the specification requirements. The use of continuous pipe rolling units to produce hot-rolled P91 alloy pipes is a more advanced method.
1.2. If you want to obtain seamless steel pipes with smaller size and better quality, you must use cold rolling, cold drawing or a combination of the two. Cold rolling is usually carried out on a two-roll mill, and the steel pipe is rolled in an annular pass composed of a variable cross-section circular groove and a fixed conical head. Cold drawing is usually performed on a 0.5 to 100T single-chain or double-chain cold drawing machine.
1.3. The extrusion method is to place the heated tube blank in a closed extrusion cylinder, and the perforation rod and the extrusion rod move together to make the extrusion part extruded from the smaller die hole. This method can produce steel pipes with smaller diameters.
We offer precision cutting of pipes in lengths from 2 inches to 60 feet and diameters from 2 inches to 48 inches. The type of cutting used depends on the size of the pipe and the accuracy required. Tolerance range is 1/8" to 1/64".
Fused epoxy resin, also known as FBE coating, is a thin thermosetting polymer coating formed by electrostatic spraying of epoxy resin powder material on the surface of the base steel pipe. FBE coating has excellent corrosion resistance. It is firmly combined with the coating on the surface of the steel pipe base, extending the service life of the steel pipe and providing constant soil pressure.
The difference between ASTM and ASME standards:
ASME American Society of Mechanical Engineers Standard
ASTM American Society for Testing and Materials Standards
First of all, it is necessary to understand the type, specification, performance and scope of use of the pipe. It is better to investigate the application of the pipe in other similar pressure pipes, and then determine the material of the pipe according to the following principles.
Good heat preservation effect: 3PE anti-corrosion spiral steel pipe has good heat preservation performance, and the heat loss is only 25% of that of traditional pipes. Long-term operation can still save relatively large resources and significantly reduce energy costs.
