Consider the following human spec 1LK0F01 (Class 150, PVDF-Lined Carbon Steel Process) from the Process Industry Practices organization. 4

You should follow the same process for 1LK0F01 as in the previous human spec examples, 3CS1S02, 1SP1S01, and 1CS1S01 with the following exceptions.

  • Piping Note 40 specifies that the manufacturer should be consulted for temperature, pressure, and vacuum limits for specific services; and that a Service Limits rule has not been specified for this piping spec. This record should have a default value for Commodity Option. In order to invoke this commodity- specific validation, you must specify the value of the Selection Basis property as either 'Fitting that requires validation of Piping Commodity Service Limits Data', or 'Fitting plus reportable piping commodity that requires validation of Piping Commodity Service Limits Data, for example, a clamp and its gasket', as required.

  • Per Piping Note 43 the bending of plastic-lined pipe is permitted, but only by the manufacturer. Even though the materials engineer has not included a record for a pipe bend in the human spec (other than this piping note), you must specify a pipe bend record for each bend radius that is provided by the manufacturer, and is permitted by the materials engineer. You should use the functional short codes of '90° Direction Change' and '45° Direction Change', as specified in the Default Piping Commodity Selection Rule rather than 'Pipe Bend'. This provides consistency for the piping designer in situations where the type of direction change fitting might differ on the basis of size within the same piping spec or between two piping specs. However, if both flanged elbows and pipe bends are permitted in the same size range, you must specify these records with different values of the Commodity Option property. We recommend that the default value of the Commodity Option property be reserved for use by the type of direction change considered to be the preference by the materials engineer. Furthermore, if multiple bend radii are permitted for the manufacturer's pipe bends, each pipe bend record must have a different value of Commodity Option, where the difference is based on the applicable Commodity Option value for Bend Radius.

  • Per Piping Note 51, the plastic lining in the pipe stock must comply with the ASTM F1545 standard specification for PVDF plastic-lined ferrous metal pipe and fittings. The pipe stock must be equipped with means to vent pressure from between plastic liner and steel pipe. This requires you to specify the Lining Material for these fittings in the Piping Commodity Class Data, and the Liner Thickness in the Liner Thickness Generic Data.

  • The 1" – 12" Spacer record should have a default value for Commodity Option. Per Piping Note 46, the Short Code for the Spacer must be defined in the Default Piping Commodity Selection Rule with a value equivalent to 'Solid ring spacer', so that spacers are considered in the determination of pipe stock lengths. Note that materials engineer has not specified the purchase lengths for the pipe stock in the human spec, nor has the requirement for distance pieces been specified. In this situation, the human spec requires more detail. Spacers (distance pieces) are not supported when Pipe Purchase Length is defined.

  • Per Piping Note 52, all wetted surfaces of all fittings, the Reducing Flange, and the Blind Flange must be lined. This requires you to specify the Lining Material for these fittings in the Piping Commodity Class Data, and the Liner Thickness in the Liner Thickness Generic Data.

  • The 1" – 8" 90° Reducing Elbow should have a default value for Commodity Option.Note that the 90° Reducing Elbow must have two size ranges, although this is not specified explicitly in the human spec. It is necessary for the materials engineer to specify the size ranges for the pipe for which the reducing elbow is applicable. So, the First Size To equals 8", Second Size From equals 1", and the other sizes are deduced from those values, as defined by the materials engineer. Per Piping Note 37, both ends of the 90° Reducing Elbow must have Class 150 flanges.

  • Per Piping Note 34, the first 1" – 12" 45° Lateral is specified as a full-sized lateral branch. This record should have a default value for Commodity Option.

  • The second 1" – 12" 45° Lateral is specified as a reducing lateral branch. This record should have a default value for Commodity Option. Note that the 45° Lateral must have two size ranges, although this is not specified explicitly in the human spec. It is necessary for the materials engineer to specify the size ranges for the pipe for which the reducing elbow is applicable. So the First Size To equals 12", Second Size From equals 1", and the other sizes are deduced from those values, as defined by the materials engineer.

  • The first 1" – 12" Flange (threaded) should have a 'Female Threaded' value for Commodity Option. The value of Short Code should be the equivalent of 'Flange' in the Default Piping Commodity Selection Rule.

  • The second 1" – 12" Flange (lap joint) should have a default value for Commodity Option. The value of Short Code should be the equivalent of 'Flange' in the Default Piping Commodity Selection Rule. Per Piping Note 32, flanged ends may be molded raised face with threaded ductile iron flanges, lap joint flanges with lap joint ends on lined pipe, or two-piece lap joint flanges with lap joints on lined pipe that meet Class 150 dimensions. Note that in this case the Lap Joint Flange does not require a Contractor Commodity Code for a Reportable Piping Commodity, as in the case of 1SP1S01.

  • The 1" – 12" Reducing Flange should have a default value for Commodity Option. Note that the Reducing Flange must have two size ranges, although this is not specified explicitly in the human spec. It is necessary for the materials engineer to specify the size ranges for the pipe for which the reducing elbow is applicable. So the First Size To equals 12", Second Size From equals 1", and the other sizes are deduced from those values, as defined by the materials engineer. Per Piping Note 35, the human spec requires a Reducing Filler Flange, where the bolts for the reduced connection are to be thread into blind holes in the face of the flange. On this basis, the value of the Bolting Requirement property in the Piping Commodity Material Control Data must be specified as 'Complete cap screw substitution for threaded holes for second size end', and you must specify a value for the Substitution Cap Screw Commodity Code in the Piping Commodity Material Control Data. Per Piping Note 52, all wetted surfaces of the Reducing Flange must be lined. This requires you to specify the Lining Material for the Reducing Flange in the Piping Commodity Class Data, and the Liner Thickness in the Liner Thickness Generic Data. Furthermore, the flange thickness in the Bolted End Generic Data for the larger end of the reducing filler flange must equal the face-to-face dimension in order to calculate the correct bolt length. This will require a special value of the End Standard property to be specified in the Piping Commodity Class Data for the larger end of the reducing filler flange.

  • The 'X' legend for the Branch Intersection Rule specifies that a flanged tee with a flanged reducer or a flanged reducing tee be used, as required, where the distinction is based on the manufacturer's standard fittings. For the size combinations, where a reducer is required, you must specify a value for the Short Code for Reducing Fitting property. If the value for the Short Code for Reducing Fitting property is specified as the equivalent of the Concentric Size Change functional short code in the Default Piping Commodity Selection Rule, then the Size Reduction Rule is used to determine the reducing fittings that are required. Otherwise, it is assumed that only one reducer is required to meet the requirement of the branch size.

  • Per Piping Note 38, gaskets are not required for connections between plastic-lined components; whereas 3/16" PTFE envelope gaskets are required for mating plastic-lined components to non-lined components. You may either specify a value of 'Gasket is not required for lined, flanged piping system' for the Gasket Override Requirement property of the Piping Materials Class Data, or you specify a value of 'Integral gasket requiring another lined flange surface' for the Gasket Requirement property of the Piping Commodity Material Control Data for each lined fitting. This value will indicate that the lined flange surface at each bolted end serves as the gasket, that is an integral gasket, where the liner thickness has been included in the face-to-face dimension of the piping commodity, such that the gasket thickness should not be represented in the 3D model, if and only if another lined flange surface forms the bolted joint. Otherwise, a gasket is required.

  • The human spec requires stud bolts by default. This bolt record in the Bolt Selection Filter should have a default value for Bolt Option. However, Piping Note 39 indicates that hex head bolts or cap screws, nuts, and washers may be required for some connections. You must specify the applicable value of Bolting Requirement from the following list for any flanged valve or fitting that requires stud bolts to be substituted with either cap screws or machine bolts. When a complete or partial substitution with cap screws (or machine bolts) is required, you must also specify a value for the Substitution Cap Screw Commodity Code property. When a complete or partial substitution with cap screws (or machine bolts) is required, you must also specify a value for the Quantity of Substitution Cap Screws property. In either case for cap screws, but not machine bolts, you must specify a value for the Substitution Cap Screw Diameter property and the Tapped Hole Depth property.

  • Complete cap screw substitution for threaded holes for each bolted end

  • Complete cap screw substitution for tapped holes for each bolted end

  • Partial cap screw substitution for threaded holes for each bolted end

  • Partial cap screw substitution for tapped holes for each bolted end

  • Complete cap screw substitution for threaded holes for second size end

  • Complete cap screw substitution for tapped holes for second size end

  • Partial cap screw substitution for threaded holes for second size end

  • Partial cap screw substitution for tapped holes for second size end

Otherwise, in the case of the machine bolts, if the piping designer is to determine when machine bolts are required, you must include a bolt record in the Bolt Selection Filter, where the value of Bolt Option is 'Machine Bolt', and the Contractor Commodity Code for the bolt record represents the applicable machine bolt.
