Welded Stainless Steel Tube for Pressure Purposes
EN 10217-7

Material: 304, 304L, 316L

Welded Stainless Steel Tube

The EN 10217-7 ss tubes for pressure purposes are outstanding tubes made of durable materials such as 304, 304L, and 316L stainless steel. Buyers may choose the suitable diameter as well as thickness as the physical variables according to their machining demands.

There are 19 sets of thickness values. Each thickness value has its own corresponding outside diameter value, and those values are shown in the table. Buyers may refer to the table in this page. With different choices of the OD and the corresponding thickness values, the tolerance values are also different. Please read the tolerance table carefully before the purchase. Besides the pipe specifications, buyers are also allowed to choose their packing methods for the tubes. There are steel crate and bundle packaging methods.

Specification

EN 10217 specifies the technical delivery conditions in two test categories for stainless steel welded round tubes which are intended for pressure and corrosion resisting purposes at room temperature, at low temperatures or at elevated temperatures.

 

This standard is applicable to the tubes with an outside diameter mainly in the range between 10mm to 508mm, all tubes are available in different sizes and thickness as our size range is based on customer's general requirements.

 

Product is made of Austenitic series stainless steel, grades in 1.4301, 1.4307 and 1.4404 are the options, durable quality is without doubt. It shall be applied for pressure and corrosion resisting equipment such as towel heater etc.

 
  • The tubes shall be manufactured from hot or cold rolled plate, sheet or strip in accordance with EN 10028-7.
  • Variable surface suits for different processing or performance.
  • EN 10217-7 tube complies with essential requirements of EU Directive 2014/68/EU.
  • Welding is carried out by qualified personnel in accordance with operating procedures.
  • Inspection document 3.1 can be specified according to customer requirement.
  • Professional engineer and prompt after service to be your backup force.
  • Punctual delivery time make stock controlling well.
  • Tolerance is accordance with the norm, specific tolerance requirement is discussable.
  • Optional supplementary requirements are negotiated and provided.
