Помогите перевести: composite make-up per 30 meters of pipe gen.

[aradanka]

Коллеги! Помогите, пожалуйста, разобраться:

"Historical and Standard onsite fitting density factors (composite make-up per 30 meters of pipe) have been applied to ensure that all categories of pipe fittings and flanges for the applicable piping specifications and size ranges have been accounted for and to determine fitting and flange quantities.

Что такое "(composite make-up per 30 meters of pipe)?"

[aradanka]

"С тем, чтобы обеспечить соответствие фитингов и фланцев всех категорий техническим условиям и диапазону размеров трубопроводов и для определения необходимых объемов фитингов и фланцев, при определении расчетных коэффициентов плотности фитингов на площадке (разъемное соединение - каждые 30 м. по трубе) использовались соответствующие стандарты и данные с аналогичных предыдущих проектов."

Это мой вариант. Помогите, может быть, он и есть верный?

А можно побольше контекста?

Piping:

Overall linear piping quantities were quantified using previous similar sized layout and racking as basis for routing of lines.

Piping line sizes not available at time of take-off were estimated by either using previous experience or by using flow rates indicated on PFD divided by nominal line velocity of 2 m/s

Where practical, physical preliminary modelling were used to quantify piping and fitting quantities for higher value lines.

Historical and Standard onsite fitting density factors (composite make-up per 30 meters of pipe) have been applied to ensure that all categories of pipe fittings and flanges for the applicable piping specifications and size ranges have been accounted for and to determine fitting and flange quantities

Valve take-off was prepared using sizes and quantities as reflected on the issued typical P&IDs

Standard piping primary supports (saddles, clamps, shoes, etc.) have been estimated using percentage of supply and pre-fabrication piping price.

Special supports (Constant and Variable Hangers) have been estimated using previous project sizing data.

Small bore pipe linear quantities have been verified using historical and standard data (as a percentage of overall linear piping quantities).

Insulation material quantities have been estimated using previous project data as basis.

(включая "наращивание" на 30 метров погонных трубы).
Данные, имеющиеся до расчетов (исторические данные) и фактические (типовые) по месту позволяют вывести коэффициент удельного количества (плотности) соединительных деталей...
