13Cr SS Q1 2 3/8 Corrosion Resistant API 5ST Coiled Tubing

Product Description

13Cr Stainless Steel API Spec Q1 Corrosion Resistant Coiled Tubing 2 3 / 8

Our products have complete specifications and can meet all working conditions. The outer diameter range of 13Cr tube we supply is from 1 1/4”(Ф31.75mm) to 2-3/8”(Ф60.325mm). All dimensions and corresponding parameters are listed in the table below, we can also customize it according to customers' requirement details.

Stainless steel coiled tubing is the widely used steel capillary tube which is ideal for use in potentially corrosive environments or transferring liquids and gases for cooling, heating, and other purposes. Stainless coiled tubing is made with the finest quality stainless tube by bent, curved, wound, or otherwise formed process around a hollow “center”. our 13Cr tube has the characteristics of restricted tolerance control, improved system safety and reliability, superior sealing performance, better corrosion resistance, etc.

Our manufacturing process generally includes: Raw material inspection → production → heat treatment → inspection & test → rewinding → packaging

We strictly control the purchase of raw materials, choose laser welding to minimize energy consumption and deformation. In the machining process we have layers of inspection to ensure the quality of the product. The inspection&test process generally includes dimensional inspection, non destructive evaluation(NDE) and hydrostatic test. We have two types of packing: wooden shaft and iron shaft.

Our core advantages (laser welding) :

Internal weld height: <0.3mm (long diameter for more types of operations)

Width of heat affected zone: <0.6 times the wall thickness

High availability: replacement of raw materials without replacement of the production line

Reliability: fusion welding > Pressure welding (resistance welding)

Groove corrosion: none
