37Mn5 steel pipe is J55 steel pipe, commonly used in oil well drilling, also used as a raw material for rolled anchor. Oil casing is an important equipment for oil drilling, its main equipment also includes drill pipe, core pipe and casing, drill collar and small diameter drilling pipe, etc. The domestic casing is made of hot-rolled or cold-drawn steel used for geological drilling, and the steel number is denoted by "Geological" (DZ). The commonly used casing steel grades are DZ40, DZ55 and DZ753.

Seamless pipes are widely used. Universal seamless pipes are rolled from ordinary carbon structural steel, low-alloy structural steel, or alloy structural steel, with the highest production volume, mainly used as pipelines or structural components for transporting fluids.
According to different purposes, the supply is divided into three types: a. supply based on chemical composition and mechanical properties; B. Supply based on mechanical performance; C. Supply based on hydraulic testing. If used to withstand liquid pressure, steel pipes supplied according to Class A and Class B should also undergo hydraulic testing.
There are many types of seamless pipes for special purposes, such as boiler seamless pipes, geological seamless pipes, and petroleum seamless pipes.
