Technical QA/QC Verification
• 100% Traceable PMI Spectrometer Logs: For stainless and alloy slotted products, we run 100% Positive Material Identification (PMI) spectrometer verification to secure accurate chemical tracking. All shipments include complete EN 10204 3.1 Mill Test Certificates mapping tensile load limits and collapse resistance data. Fully certified for independent inspections by SGS, BV, or Intertek.
• Capital Security Guarantee: We remove international cross-border financial risks for industrial filtering and infrastructure contractors by approving large-volume project shipments under 100% Irrevocable Letters of Credit (L/C) at sight financial frameworks.
Internal Protection & Ocean Logistics
• Hexagonal Marine Bundling & Rigid Bracing: Slotted pipe groups are bundled tightly using heavy high-tensile steel straps and thick canvas lifting loops. Bundles are nested securely inside maritime shipping containers with extensive structural timber bracing and lashing wires to prevent dynamic cargo movement across open sea lanes.
• Complimentary Extended Destination Port Demurrage: SXY Steel Group automatically includes 14 to 21 days of extended free container demurrage at your destination port, providing your local customs clearing agents with ample operational time to handle import clearances.
Description
Slot and perforate on the pipe body to be slotted pipes. The types of slot are Perforated, Rectangular slotted, Trapezoid slotted, Bridge slotted, Wire wrapped screen, Mechanical cutting, Compound slotted pipe.
The slotted pipe is using in oil exploration to prevent sand, decrease oil well repaired, increase oil well’s strength, integrality and stability of keeping off sand.

3. Slotted type
(1)Straight Slots
Cut at a right angle to the liner, this slot type shows the same diameter from the inside to the outside of the wall. Although straight slots are cheaper to produce, they are less effective in sand control compared to keystone slots.
(2)Keystone Slots
Cut at a slight angle, keystone slots, or tapered slots, are larger on the inside than on the outside, making sure that any particle entering the slot can pass through freely without clogging the slot.
Keystone slots are more expensive to than straight slots, but lower the risk of production losses due to plugged liner slots.
(3)Slot Patterns
Whether you want your slotted pipe with a line, staggered, gang, overlapping, horizontal, or any other pattern, we can cut them all.
Among all slot patterns, the following three are the most common.
(4)Line (Straight) Pattern
In the line pattern, slots are placed evenly in identical bands around the pipe, forming straight lines of slots across the length of the slotted liner.
(5)Single-Slot Staggered Pattern
In the single-slot staggered pattern, bands of evenly spaced slots are placed around the pipe. Slots in different bands are offset (staggered) to each other.
The single-slot staggered pattern preserves the strength of the pipe and provides an even distribution of the slots over the area of the pipe.
(6)Gang Pattern (Multiple Staggered Pattern)
While having the same overall layout as the single-slot staggered pattern, the gang pattern places two slots, cut at close proximity, instead of just one slot at each position.
Slotted pipe with a multiple staggered pattern has been shown to withstand higher torque during installation and provide better resistance to deformation under thermal load compared to the single-slot staggered pattern, making it well suited for application in steam assisted gravity drainage (SAGD) applications.

Application Areas
Steel is widely used in steel structure workshops, bridge frames, main structures of high-rise buildings, and infrastructure construction (such as highways, oil and gas pipelines). Its high strength properties ensure load-bearing stability and seismic performance. In ship manufacturing, steel is used to build hull structures, decks, and internal components. Hot-rolled coils rely on their load-bearing capacity to adapt to harsh environments.

Factory workshop
With a commitment to excellence, innovation, and sustainability, the company has established itself as a trusted partner in the international steel industry.After nearly two decades of relentless endeavour, our client base now spans over 110 countries and regions across Europe, the Middle East, South America, and Southeast Asia.
