What is API 5L Grade B Pipe? API stands for American Petroleum Institute and 5L stands for five-layer schedule pipe with external coating of resins, there are two types of API 5L Gr B pipe material such as high-density polyethylene (HDPE) and low-density polyethylene (LDPE). There are five kinds of grades available to meet different environments, as follows: Grade A, Grade B, Grade C, Grade D and Grade E. The pipe wall thickness can be selected from Schedule 40 up to Schedule 160 to meet the requirements of different working pressure and temperature levels.
API 5L Schedule 40
API 5L pipe is available in a number of different schedule ratings. Schedule 40 means that there are 40% of a pipe’s surface area (by length) left after being cut through its thickness to reduce pressure loss and maintain strength. API 5L Grade B pipes must be made from ASTM A53 steel, which can be produced by three different processes: open-hearth, electric furnace or induction furnace. The differences between these processes result in slightly different grades for each process that translate into minor differences in physical properties and weldability. All API 5L Grades A through D are suitable for welding with low hydrogen electrodes; API 5L Grades X65, X70 and X80 require special flux-cored wires because of their high nickel content.
API 5L X42 PSL2 Pressure
API 5L Grade Pipes are made of X42 PSL2 with pressure rating 4000 PSI. API stands for American Petroleum Institute, a global association that develops standards for manufacturing, inspection and construction of oil and gas related equipment. The API 5l grade B pipes use first grade material from genuine vendors which are known for their quality in producing steel pipes according to various standards worldwide.

API 5l gr b pipe prices
These are superior quality of pipe and widely used in industries such as oil and gas, chemical and other industrial applications. API is a leading manufacturer and supplier of API5L pipes, which are available in SS400 pipes. These SS400 gradeB pipes have been tested for ensuring high level of accuracy with regards to thickness, uniformity, mechanical properties, weldability and corrosion resistance. Apart from SS400 gradeB pipes also provide many more specifications in variety of sizes ranging from 6 inches to 114 inches diameter and wall thicknesses ranging from 9mm to 48mm among other features. Nowadays these API 5l gr b pipe suppliers are extensively demanded by numerous industries owing to its solid construction which enhances its durability as well as reduces maintenance cost.
Bending of pipes
The API standards also provide requirements for bending pipe. These are broken into two types: fabrication bends and field bends. Fabrication bends are made in accordance with specified procedures and tools in a shop environment, and should result in an ideal bend that conforms to specification tolerances. Field bends, on the other hand, do not have these restrictions, as they must be made in an open-air environment with limited materials available. Certain allowances will be given for deviation from nominal dimensions when required by installation parameters or special applications. The standard lists four classes of field bend according to how close they can get to their maximum permissible deviation without failing quality requirements; Class 1 through Class 4 (more severe bending).
