常见问题
•Do Russian flanges fit EN or ASME piping systems?
GOST flange dimension tables largely parallel EN 1092, and many sizes interchange directly; ASME B16.5 patterns differ and require either an adapter spool or flanges machined to the ASME drilling. State the standard your plant uses and suppliers will either confirm interchangeability or machine to your template — both are routine requests.
•Can expansion joints be engineered for my specific pipeline?
Yes. For bellows and fabric compensators you provide diameter, pressure, temperature, medium and expected axial or lateral movement. The manufacturer calculates the bellows geometry, selects the steel grade and returns a datasheet with cycle life. Custom units in non-catalogue diameters are normal production, typically within 20–35 days.
•What pressure documentation comes with fittings and flanges?
Each batch ships with material certificates stating steel grade and heat number, hydraulic or pneumatic test protocols where applicable, and EAC conformity documents. For critical service, additional ultrasonic or radiographic weld inspection can be ordered and documented — specify the inspection level in your request for quotation.
•What is the minimum order for brass and small-bore fittings?
Small fittings are sold by carton — usually 50–500 pieces per SKU depending on size. Distributors typically assemble mixed pallets across dozens of positions, and suppliers will consolidate several product families into one container so you reach economical freight without overstocking any single item.
•How fast can a mixed piping order reach Central Asia or the Gulf?
Stock items dispatch within about a week. Trucked cargo reaches Tashkent or Almaty in 7–14 days door to door. Sea freight from Novorossiysk to Jebel Ali typically runs 20–35 days including port handling. Custom-machined items add their production time, so split urgent stock lines from engineered positions when ordering.
