• SEAMLESS VS WELDED BW FITTINGS

  SEAMLESS VS WELDED BW FITTINGS Butt weld fittings are available in seamless and welded execution (seamless for bore sizes below 24 inches, welded for sizes above 24 inches). Seamless buttweld fittings have no seam welds and are therefore considered superior to welded BW fittings (a weld is always a

• PIPE BENDS

  PIPE BENDSA pipe bend is a generic term to indicate a fittings that changes the direction of the piping system (technically, elbows are pipe bends too but of a standardized type in terms of angle degree and direction). The term “pipe bend” refers to a fitting that offsets the direction of the pipe w

• BUTTWELD TEE

  BUTTWELD TEEEQUAL TEEAn equal tee, otherwise called straight tee, is a buttweld fitting used to branch a pipeline, or any other pipework, at 90 degrees. Equal tee asme b36.19A pipe tee is defined “equal” when the bore size at the run and branch sides have the same diameter. An equal tee is, therefor

• HEAT TREATMENT OF PIPES

  Heat treatment is used to avoid or alleviate the detrimental effects of high temperatures, which are unavoidable during the welding process. The heat treatment required and the recommended temperatures and holding times vary among metals. They are specified in ASME B31.3, Table 331.1.1, Requirements
